Those of you who’ve known me (or the blog) for long enough will know about my other life.
Back in the day, I used to be a swimmer. Specifically, a Channel swimmer. I’ve swum the Channel twice and done other long open-water solo swims. (You can read more about all that here).
But Adam Walker‘s sea swimming accomplishments are something else. Adam was the first British person to complete “Oceans Seven”, thought to be the toughest seven sea swims in the world:
– English Channel 2008 (finished 11 hours 35 mins)
– Two-way Gibraltar Straits 2010 (finished 9 hours 39 mins – he broke the British Record one way and was the first Brit to swim back)
– Molokai Straits in Hawaii 2012 (17 hours 2 mins)
– Catalina Channel in USA 2012 (12 hours 15 mins)
– Tsugaru Channel in Japan 2013 (15 hours 31 mins) (the first British person to complete this swim)
– Cook Straits in New Zealand 2014 (8 hours 36 mins)
– North Channel Ireland to Scotland 2014 (10 hours 45 mins)
So when Adam asked if he could grab a guest-blog spot on TFW, I had no hesitation. If I still have any open-water swimming readers, Adam’s story and stroke technique advice will be golden for you. And for the rest of you? Be inspired by his story, and consider reading his book “Man Vs Ocean” by Adam Walker (published by John Blake Publishing and available at Amazon here – Man Vs Ocean, Adam Walker, Amazon).
Over to Adam for some serious technique talk.
On 6 Aug 2014 I became the first British person to swim the hardest seven ocean swims in the world, known as the Oceans Seven.
My swim stroke was the conventional style of a high head and winding my arms, entering long and flat.
I trained with this style for 18 months, resulting in a ruptured bicep tendon whilst swimming the English Channel. Having completed the swim I had to have two operations. The surgeon told me that the bicep tendon had attached itself to the supraspinatus, and they were unable to separate them. He advised me to give up swimming as the arm rotations would irritate it and cause more injury. He said “If you do another long swim you will have serious long term problems!”
Giving up was not an option for me. I love the sport so much. So I began studying the front crawl stroke and how to take pressure off the shoulder, limiting irritation, and becoming more efficient.
At this stage I wasn’t concerned with speed, I just wanted to find a way to prolong my swimming career. Here’s what I learned.
After many months of practice and video analysis I established that having a still head looking downwards is critical in the stroke: if it’s not still, you could zigzag.
If you immerse your head then your legs will come up if you are on your side. It’s better to work with the water than lift your head up (which takes energy), not beneficial when the head is the heaviest part of the body.
I thought about other sports such as golf, cricket, bowling, tennis and cross country skiing – they all use core stomach muscles to instigate the initial phase. Therefore it didn’t make sense for me not to use rotation as part of the swim stroke.
Rotating using the core only, allowing the hips to push the arms forward instead of throwing them overhead had a number of big benefits:
– Using fewer muscles
– Less impact when entering the water
– Reduced pressure on the shoulders
– Stronger propulsion in the stroke
– More length out of the stroke
If I drive the arm/hand into the water, I am using my chest as well to do this, using more muscles than necessary. Using the core helped keep my hand and arms as wide as my hips. If your chest dominates, more often than not they will drive into the centre line, particularly when you breathe.
You will then have to push them out again in order to pull back which takes time and is an added unnecessary movement. By driving them into the centre you have the potential to pinch tendons and cause friction which will eventually tether and cause significant damage (something unfortunately I know a lot about!)
Early arm entry
I was taught to enter my hand into the water as far out in front as possible to gain a good pull. However, if your hand enters the water early with a bent elbow and then extends under water this creates less resistance and will take pressure off your shoulders.
If you think about diving off a block in a race, they only allow you to go 15 metres under water. Why? Because you are faster under water than you are on top of the water. Therefore the sooner you get your hand and arm into the water the better.
I discovered that by holding the front recovery arm in place until the stroking arm is just about to enter the water, I gained constant momentum. This aids with stability, which is necessary if you get knocked by a competitor or if a wave is about to hit you. This happened to me in the English Channel with my old stroke and I was flipped onto my back.
Pulling to your hip only is your ‘power section’ – beyond that it turns into a tricep movement with your power significantly reduced and delaying the time needed to get your hand back in for the catch.
My leg kick is just enough to keep me afloat, nothing too vigorous. 70% of energy is used up in your legs and you don’t get that benefit back. The kick is a sideways kick as you are swimming hip to hip (never flat).
By carrying out a simple two-beat kick I’m not wasting excess energy and am limiting the calories burnt. This is also important in colder temperatures.
My suggestion is to swim the majority of a triathlon with a two-beat kick, then kick a little more in the final 50m or so to get blood flow into the legs in readiness for transition. The limited leg kick will serve you in good stead when you get onto the bike as they have had limited use. On my 17 hour Hawaii swim, when I climbed out of the water, my legs were so fresh they didn’t feel as if they had be used.
How my new stroke technique has saved my career
This stroke, which my clients are calling ‘The Ocean Walker’ technique, has not only saved my swimming career but meant I was the fastest man on a 21-mile two-way swim in Windermere, and completed all seven channels including fastest British crossing of Gibraltar Straits one-way, and became the first British person to do a two-way crossing.
I’ve had three operations in total on my left shoulder, I can’t sleep on that side and I can’t hold over 10 kilos of weight with a straight arm, yet with the ‘Ocean Walker’ stroke I can swim 17 hours and am 1:15 mins faster over 1,500 metres and 5secs faster per 100 metres.
And my stroke rate has gone down from an average of 72 SPM to 52 SPM, showing that holding form in the stroke is generating more speed. I am saving 1200 strokes per hour! I am not pulling any harder than I did previously, actually if anything I am pulling with less power, showing the importance of body position and efficiency.
What I have realised is the key to swimming efficiently is to make the water work with you. By being relaxed, getting body position right and reducing resistance you will go faster.
The best athletes in the world are normally the ones who make it look effortless, use timing to their advantage and are efficient in what they do. Just look at Roger Federer or Usain Bolt!.
