Underwater Swimming and the Search for Evidence it's Good

Day: Thursday
Duration: 15 minutes
Workout: 10 underwater lengths with about 45 seconds rest between each (pool=30 metres)
Food: eggs & strawberries with cocoa, an hour later.

I am trying to find out whether underwater swimming can benefit overall fitness. I have mentioned before that I read breath holding can increase growth hormone production, but I now can't find the article.

Given its nature and how it feels, I have a hunch it has to be beneficial, but it would be nice to see some research. Either way, our gym is closing for refurbishment next week and their replacement services do not include a pool - so my ambitions to progress with the underwater swimming will be prevented, thus depriving the world of at least some evidence, albeit n=1... ...

Random, Intense Swimming

Thursday, 12 minutes at Woodcock Sports Centre Swimming Pool, Aston University.

First, two lengths front crawl warm up.

Then, 10 lengths front crawl, trying to keep 4 strokes between breaths and work as hard as I could for the distance. After 5 lengths, I was struggling not to breathe more, but focused on controlling it. I reckon I was working at 85-90% and was pretty out of breath by the end.

Finally, after a minute of rest, two underwater lengths, with about 1 minute of rest between. I got the usual panicky lung spasms towards the end of each, but swam through them.

The pool is 30m.

I should do more underwater lengths - perhaps 10 in a session sometime. They really are a unique addition to a varied portfolio of activity - no other part of my program involves breath holding, which I recall reading has various benefits. It certainly makes me feel good afterwards and I can't help thinking it must contribute significantly to overall fitness.

Food: Eggs, raspberries, blackberries, coconut cream, cocoa. Divine. ... Read more

Swim Sprints

Location: Woodcock Sports Centre Swimming Pool, Aston University
Date: 9th March

5 x Front crawl length, 95 - 100% effort.

15-20 seconds rest between each length; each length took about 25 seconds.

Total time: 5 minutes

Post Workout Nutrition: scrambled eggs with melon and cocoa powder, an hour later.

Swimming sprints never fail to leave me feeling violated. On the first few lengths I was only really at 95% effort, but lung burn had set in by the third, so I was already looking for the end. I hadn't decided whether I would do 5 or 6, so opted to up the intensity to 100% in return for only doing a further 2. I was still breathing heavily in the shower a few minutes later. I suspect the Easter weekend has robbed me of a little fitness. Nothing a few Tabatas can't solve. ... Read more

Coldest Swim Ever & Long, Slow Barefoot Road Run

Location: Lake Vyrnwy
Date: 6th & 7th March

Workout 1
Wild swim in the lake - 30 seconds!

Post Workout Nutrition: none - fasted that day.

----

Workout 2
Run around the lake, partly on hills and ridges, mostly on the road - 2 hours and 53 minutes, 13.3 miles

Pre-Workout Nutrition - dinner the night before - salmon & venison sausage starter, lamb (I left that potato!) & veg; nuts to finish.



Post-Workout Nutrition
- anti-inflammatory bonanza: breakfast - scrambled eggs, one of Mrs M's poached eggs, grapes and nuts; lunch: salmon, sardines, avocado, celery, spinach; dinner: mackerel, celeriac & carrot mash, cabbage, onion, coconut butter.

Mrs M and I spent the weekend at a hotel by a lake in North Wales, a fantastic location for wild swimming and hill running. Here is what I got up to, along with some photos.

Day 1: The Swim

With a lake like that on my doorstep I couldn't possibly resist a wild swim on the first morning. I was out for about 7 am, by which time the sun was already loitering behind the hills and creating some wonderful skies:





After a little walking, daylight arrived, and I noticed there was the remnants of ice on the surface of a river that fed the lake. You can just make it out on the left.



When I found a perfect spot for swimming, there was a sign which said "No Swimming." Being the naughty kind, I decided to ignore it.

With hindsight, I am glad, because when I ran round the entire lake the next day I discovered that these signs are posted anywhere where swimming is viable. It is not clear whether this is because it is dangerous, or for some other reason. If there were danger, you would think this would be mentioned, given the additional deterrent it would create.


No swimming?


Swimming!

This was the coldest wild swim I have ever done. I managed 30 seconds. When I emerged, I had already started to feel a kind of dull ache to my bones. It took 10 seconds before I was able to enjoy the 'warmth' of being out of the water - until then I was in pain.

I took this photo on the way back to the hotel:



Later, I took advantage of the facilities for yet more self-punishment, spending 15 minutes in this dry sauna at 94 degrees. I really didn't want to be there for the last 5 minutes, but I figured that in the same way as the extreme cold earlier would help me tolerate mild cold, the same would be true for hot.


Sauna: 95 degrees hot

Then I had a cold shower. Only afterwards did I notice the ice machine on the left. I am not sure what I would have done with the ice - presumably just rubbed it on my body. Seems like a clumsy way to get cold compared to my earlier activities.

Before you ask - there was a separate supply of ice by the water jugs, so I don't think it was for that!


Ice - for rubbing on the body?

Finally, the obligatory jacuzzi, with view of the lake....




Day 2: The Run
The plan was to do one of those long, slow, easy runs that builds up stamina but doesn't unduly stress the body. I had done a 3-hour run
on hilly terrain a couple of weeks back, emerging relatively unscathed - so this seemed like a slam dunk.

I took this panoramic shot of the valley around which I would be running - starting from the left, going down to the end, and back towards the camera. Mostly, I planned to stay on the hills and ridges. The map indicated limited paths, but the hills looked grassy so I would go 'off piste'. Click for the large version.


The planned route - left to right

I got up at 5.30am and tooled up - it was a freezing morning, so it was the full burglar outfit: black hat, gloves, leggings, top, Vibrams and even the leg warmers for my ankles. Other essentials were map, compass, money, mobile phone (with GPS tracker) hotel key and waist bag to carry it all.


The full burglar outfit...


...and survival kit


6am, at the start...


15 minutes later, the sun threatens to emerge

Initially, I ascended into the forest and onto the ridge on the South side of the lake. You can see the clockwise route on the GPS tracking screenshot further down the post. Once I was on the ridge, the sun started to blaze, making it hard to capture pictures:


At some point on the South side, I remembered why I normally only attempt paths marked on the map. It always seems like a good idea when you are studying the map at home - those contours seem so easy to stride across in your mind's eye.

However, the firm, flat terrain I had imagined turned out to be all kinds of dense heather, boggy marsh and sundry other un-runnable ground. So after 30 minutes of struggling through them I lost patience and headed due North...


...through the forest...


...and back out into the open.

I then took the nearest path directly down to the road - I figured it would be a great opportunity to test out my barefoot running style in a more controlled environment.


Following the path down to the road.

Going downhill was quite steep but but a good downhill practice - I have been learning to take short, quick strides in the Vibrams to limit the risk of catastrophe at high speeds on slippy ground.

Earlier, the first 10 minutes of the run had been on the road, and felt incredibly natural and easy - so I was looking forward to more. At this point I had been running for about 70 minutes.


Back on the road - glorious sun and steady running....



Did I mention how quiet it was? Two hours later, this sheep was the first living creature I had seen:



By now I was pretty thirsty, so I drank from this stream:



At about 2:15, my feet started to hurt and my legs became tired. My energy system was humming away beautifully and I felt I could have run for hours... but the legs and feet had simply not been exposed to the sustained road running they were now dealing with.

By now the sun was higher and I was able to get some great shots of the lake as I headed back to the hotel along the North shore.





During the final 20 minutes I had to resort to a slightly heel-first gait to give my feet and calves a rest. My legs were much more tired than I had expected, so back at the hotel I plunged them into a cold bath to help recovery. I followed this with an 'oily fish' day in the hope all that omega 3 would do likewise.

Finally, I enjoyed breakfast with a view of the lake I had just run around....



Below is the GPS output from my phone. Not exactly accurate to the nearest 10 metres, as you can see - I did not do a long swim in the last half hour!



Even less accurate was the speed and altitute graph. Click on the picture for a bigger version. Considering the last half of the run was done on a flat road 300 metres above sea level, the claimed altitude of nearly 1000 metres at the 2 hour mark makes no sense at all. There isn't a mountain that high for miles around!

Swimming Sprint Intervals

Location: Woodcock Sports Centre Swimming Pool, Aston University
Date: 12th February

6 x Front crawl length, 95% effort.

15-20 seconds rest between each length; each length took about 25 seconds.

Total time: 5 minutes

Post Workout Nutrition: none - fasted until dinner.

After the 3-hour fell race on Sunday, the burpees on Wednesday and 90 minutes of walking to and from work every day this week, I felt like yesterday's workout really needed to be easy on the legs. Swimming felt like a good compromise. It does use the legs, but in ways sufficiently different from the other weight-bearing activities.

I am on a roll, fitness-wise. I didn't even think about these intervals. I just got on with them and somehow tolerated the pain better than usual. I think that's often an indication that you are getting fitter. The pain is still there, but you embrace it.

These were pretty much like Tabata intervals but with the protocol adjusted by practical factors like the length of the pool; and the number of intervals was reduced because each one was longer than 20 seconds.

For once, the whole session passed without my goggles leaking. Those public pools are so full of chemicals I swear that regular users have lighter hair than the general population.

Thank Goodness for Swimming!

Location: Woodcock Sports Centre Swimming Pool, Aston University
Date: 13th October

5 x Front crawl length, 95% effort.

15-30 seconds rest between each length; each length took 20-25 seconds.

Total time: 5 minutes

Post Workout Nutrition: Six scrambled eggs - with a plum and cinnamon, 50 minutes later

When I need to do some intense exercise but my legs need rest (after this failed fell run at the weekend) and my upper body needs rest between BBS sessions, swimming always comes to rescue.

I tried a slightly different technique today, which I have updated in the web page about front crawl. It felt faster, more natural and less hard on my triceps. ... Read more

10-Minute Swim HIIT Session (including showers)

Location: Woodcock Sports Centre Swimming Pool, Aston University
Date: 29th September

6 x Front crawl length, 95% effort.

15-45 seconds rest between each length; each length took 20-25 seconds.

Total time: 6 minutes

Post Workout Nutrition: Modified Primal/Paleo Breakfast of Champions - with one plum (recipe here), 50 minutes later

[one plum because I'm on a ketogenic stint and modified because I poured the coconut cream around the cooked egg like milk over porridge rather than mixing it in during cooking.]

I didn't quite manage 100% effort this time for two reasons.
  1. My left calf kept cramping when I really went for it.
  2. I had a terrible night's sleep and was not quite as fired up as I could have been.
That said, at the end of the 6 lengths I felt duly violated, so I think I did the required damage!

I will now rest until Sunday (5 days rest) in preparation for another Welsh mountain race, this time a little less severe than the monster earlier in the month.

I will not be running in Vibrams this time unless they arrive in the post in the next 3 days - I had to return them because they developed a hole. More on that in a future post about Vibrams.

The 'Buttermere Duathlon' and Other Exploits

Location: Buttermere Valley, The Lake District, UK
Date: 10th-14th September 2009

Day 1: Brief Lake Swim
Day 2: 800m Ascent at Sunrise, then Lake Swim
Day 3: Another Swim and Treetop Workout
Day 4: 'The Buttermere Duathlon'

Day 1 - Brief Lake Swim
When we arrived at Buttermere Valley it was overcast, but mild. I was determined to make the most of every opportunity to swim in the cold, clean, clear water of the lake, so I paddled out and splashed around for a few minutes .

I planned to increase my exposure time with each day. Although September is the warmest time for lakes in the UK, the cold still took my breath away when I went underwater.

In the evening we ate shoulder of lamb with vegetables.
Day 2 - 800m Ascent at Sunrise, then Lake Swim
The ascent of Red Pike from Buttermere valley is a steep affair. I ran it in 39 minutes a couple of years ago and I couldn't walk the next day. That was before I realised that running every mountain as fast as you can is not necessarily the way to better times.

You gain about 700 metres in height over a distance of less than half a mile. A good portion of the route has stone steps. Imagine going up the Eiffel Tower via the steps - twice, with a few dozen extra flights for good measure. If you are taking it easy, you take one step at a time. If you are racing, two.

During this ascent I took my heart rate at regular intervals. It averaged about 150. This is a little more than I wanted, but it still felt easy. In any case, given that I wanted to hike without resting (except when taking my pulse!) this was as easy as I could make it on this gradient.

My camera stopped working after this first photo - it shows the mist over the lake; but from my photos of previous years I have the following: this is where the steps begin - not too steep at first. The path then continues through the woods. On the right hand side of this photo you can see the scar of a waterfall through the forest leading up to the hanging valley - the path follows, roughly, that waterfall. Here is the peak of Red Pike taken from a different part of the valley: - it's the pointy one, roughly in the centre of the mountain range.

This was a truly spectacular morning, so I must put into words what I could not capture with the camera:

By the time I had reached the flank of Red Pike, the sun had emerged in all its glory, bathing that side of the valley in a rich orange glow. I've run in this valley on many occasions, often witnessing some beautiful mornings - but I can honestly say this beat all others.

I scrambled the final metres to the summit, reaching it in 70 minutes. I stood surveying the view. There was almost no sound to be heard and barely a breath of wind.

The sheep, dotted around the flanks Red Pike and its side-kick Dodd, were unusually silent, perhaps knowing it would be churlish to bleat in the face of such majesty. The only sounds came from the twittering birds, too innocent to know better, as they flitted around the grassy slopes; and of course there was the distant, low sound of the waterfall.

I tried the camera again, cursing its failure to work at such a moment. It was surely ashamed to function, knowing its primitive lens couldn't possibly capture the beauty of the scene.

In the distance, the Newlands and Borrowdale valleys slumbered beneath duvets of cloud and mist, awaiting the attention of mother sun, whose sole affection seemed for now to be directed our way.

Forget standing on the bow of the Titanic with a Kate Winslet. I know where I'd rather be.

After a few moments, I began the descent. It's almost impossible to descend via this route without feeling as if you are taking the mountain with you. The slope is eroding with every footstep - great for breaking a fell runner's footfall and allowing a rapid descent, but not great for the mountain. I have always said Red Pike would make a great fell race, but I am guessing the owner, quite rightly, forbids it.

By the time I reached the steps, both Vibrams had taken in stones and grit. Even the Flows could not keep this stuff out. I stopped briefly to deal with it.

Once re-shod, I made the final descent down the many stone steps, bronzed for 15 minutes by twin suns, as the mirror-still lake reflected the surprisingly powerful September rays, now blazing above Hindscarth edge on the other side of the valley.

105 minutes after I set off, I was back lakeside, and ready for a dip. Once again, I was disappointed not to be able to capture the scene with my camera: millpond stillness with a thin layer of mist, glowing from the sun's rays.

The cold water, as ever, took my breath away at first, but once I was accustomed to it, I did about 10 minutes of front crawl and paddling on the shoreline, marvelling at the clarity of the water and enjoying the cooling effect on my legs.

Back at the hotel, breakfast was scrambled eggs with tomato.

Later Mrs M and I walked around the lake, which took around 2 hours.

Lunch was a baked trout with salad. After a nap and some reading, in the evening we had shoulder of lamb (again!) , after which Mrs M capitulated and consumed a banana and toffee cheesecake: .
Day 3 - Another Swim and Treetop Workout
My enthusiasm had clearly had an impact on Mrs M because the following morning I managed to persuade her to accompany me to the lake for a pre-breakfast, dawn swim. Only the cows were up before us .

Armed with fresh batteries for the camera and treated once again to a clear sky, I was able to capture a little of what I had experienced the day before. This was the view of the lake at the point where the path meets it . This is a view of the inviting water's edge where we swam ; and the obligatory Vibram shot from in the water, showing the 'twin suns' keeping us warm .

I swam out about 30 metres then back in to shore twice, spending about 10 minutes in the water. I was testing my ability to swim front crawl for a sustained period without my breath being taken away by the cold.

I wasn't telling Mrs M, but the next morning I planned to swim across the lake at its narrowest point (about 300 metres.) I wasn't telling Mrs M because last time I mentioned it she insisted she would row alongside offer assistance if needed. I felt this was overkill and a scenario with the makings of a classic comedy sketch.

For breakfast, a coffee.

Later, we went for a woodland walk, where I resisted the temptation to take another dip here . It was mainly the thought of having to dry out the Vibrams again that stopped me, although now I think about it, I should have simply braved the rocks with bare feet.

We did some sunbathing and ate some lunch - for me a classic medley of healthy fats (salmon, sardines, avocado, Brazil nuts) with a token red pepper which I ate like an apple.

Mrs M then whipped out a book, leaving me somewhat at a loose end. So, I monkeyed around in the trees, seeing what exercises I could do and, rather childishly, demanding Mrs M take photos at regular intervals. This was in part to punish her for having brought a book without suggesting I bring one too, and in part so I could include them in this post.

I could have done a good workout, but I was mainly playing. I did some balancing , some pulling up , some handstands and some rock lifting .

On the way back we picked some wild blackberries for dessert .

Later we went for a curry in Cockermouth, at the Spice Club. Nice place. I ate this , but am including a photo of Mrs M's plate since I ended up eating half of that, too. She made a textbook blunder by treating herself to a garlic naan, which of course filled her up too much to finish the Tandoori platter. Bread: seems like a good idea at the time but rarely delivers on its promises.
Day 4 - 'The Buttermere Duathlon'
On the final morning I arose early and did not encourage Mrs M to join me for my morning swim. She didn't come.

I then ran halfway round the lake, to the point where it is at its narrowest. This photo from last year shows it . For obvious reasons, this time I could only take with me my shorts and my Vibrams.

I then spent 30 seconds in the water, acclimatising to the cold, before setting off across the lake.

Have you ever noticed how running outside is harder than running on a running machine? It seems there is a parallel with swimming in a pool vs. swimming in a lake. The lake was harder, I suspect for the following reasons:
  1. The cold
  2. An inability to see where you are going once you get into the deep water
  3. Not getting a brief rest every 30 metres (at the end of each length)
The crossing took about 10 minutes. I never doubted I would make it, but nevertheless was given new respect for people who undertake (or are involuntarily thrust into) greater aquatic challenges than this.

Once you are out there in the deep, you really are on your own. When you are running, you can stop. Standing still takes no effort. Treading water, does.

I could tell that the cold and the effort had affected me because I was initially unsteady on my feet as I began running back. Here is the route marked on a satellite image of the valley: .

Thus did I compete in (and win) the inaugural event of the Buttermere Duathlon. Estimated time: 45 minutes. Admittedly there was not a great turnout, but look at it this way: if I can persuade my running partner to take part next year, I will double the field!

Breakfast was melon followed by scrambles eggs, tomatoes and mushrooms .

Then we drove home to the city :-(
