Just posted this online having seen many people dismissing swim training. Interested if anyone has an opinion?
I think people misjudge the comparative gains that can be made on the swim, it’s like there's a confirmation bias affect, i.e. the bike duration is longer, therefore it’s easier to save time bike training.
How many people think about gaining 60 minutes on the bike with 6-9 hours a week average bike training, vs those that think about gaining 20 minutes on the swim with 2-3 hours a week average swim training?
What about if you invested a comparative amount on swimming? How many who are prepared to spend £3000 on a bike are happy to spend £1000 on swim coaching?
A good ironman swim isn’t just about swim training, its also about confidence, start position, managing the turns (how many optimise their swim line or draft for the whole swim course?) swimming mid pack front pack also puts you in faster moving water (overall pull from other swimmers) so there is an small exponential benefit in open water
A good ironman swim is better than the sum of its parts, as suggested by someone else, a good swim is less tiring and in my experience set you up for a more positive day.
Now the big benefit, a faster swim means a better legal draft on the bike. Not cheating, draftzone is 10m (5 bike lengths), 8 meters off someones back wheel. Just like the pro’s do, youll have a much better chance of sitting in a draft legal (and faster moving) line of bikes if you come out mid front pack after the swim. There’s still a massive draft gain at 10m, far better than pushing round the course on your own.
