I removed all running from the training plan for this week to try to get the tendonitis a chance to clear. I took the opportunity to push the swim distance on a lot.
Over Tuesday and Wednesday, I did two swims which covered the IM distance of 3.9km and for the week, I covered just under 8Km. I wanted to push it quite a lot to see how I handle long swims with no breaks (as in 2.5km straight instead of 5x500m with 20 seconds break in between each set). The answer turns out to be quite well.
There are several defined periods, I find after about 200m, my arms get a bit sore. This lasts about 200-300 meters and then disappears (essentially the warm up). Some time between 750m and 1Km, I enter a period of flawless swimming. It only seems to happen when the water feels cold, so I must be fully warmed up at this stage. I can only describe it as “fish mode”. Nothing feels tired, my HR and breathing stabilise to a comfortable level and I can swim my fastest then.
After about 2km, my form starts to get more ragged and I started to lose concentration. Bearing in mind this is after around 80 laps of the 25m pool. I concentrate hard on form at this time. Worse form means less efficiency, which means slower swimming which equals worse form and so on..
Finally, the minute I switch from counting the lengths I’ve done to how many I have left (typically around 250m from the end and the light appears at the end of the tunnel), my form returns and I can almost always finish strongly.
Holding concentration really is everything. It’s interesting to note that many ultra endurance swimmers have physiological problems. It is, after all a very solitary pursuit. The Man Who Swam the Amazon describes Martin Strell’s mammoth swim of 3,274 miles from the source to the finish of the Amazon – one of the most dangerous rivers in the world. At the beginning of the swim, he had people in boats looking out for crocodiles, snakes and the awful sounding Caribu fish (they are an invasive species..). In the last few days of the trip, Strell declared that he had been talking to the fish under the water and had made friends with them. There would be no need for danger spotters anymore.
I plan to make friends with as many of the species in lake Zurich as I can prior to the race.
On Saturday, I spent 5 and a half hours on the bike with Justin, another guy training for IM Switzerland. The weather for the first 2 hours alternated between ‘heavy rain’ and ‘downpour’. It certainly wasn’t easy but we completed it eventually, after a puncture. Coming back over the Sally Gap, we experienced some very unusual conditions – small pockets of blue sky, almost like the eye of a hurricane surrounded by rain clouds, inside which visibility was almost nothing.
I have a wrist band for when times get very tough like they did on Saturday. It’ll be no stranger to endurance athletes. It simply says “Harden the F**K Up”. IM training is no time to feel sorry for yourself. The HTFU band is a good reminder of that.
