Wetsuits are made from closed cell neoprene..... washing them has zero benefit on the material*, but may help protect the stitching if its of poor quality, but in reality, the best thing you can do for a wetsuit and its stitching is to keep it dry after use.
(sold wetsuits for sailing for 15 years, so have a little knowledge)
*assuming its not material covered, which no swimming wetsuits are
I followed the 'Competitive' plan religously.... a few observations:
I wholeheartedly agree with Flyaway.... its easy to underestimate the cumulative impact of putting stuff off, being tired at work, and missing family birthdays/parties/gatherings....
I also agree with Seren, that the swim programme is pretty much impossible.... god knows, I tried.... further more, a decent time in IM is built upon the bike, so why the heavy focus on the swim, and so little effort on the bike?
For my next one, I'll make my own plan... still based on base-build-peak, but with LOTS more cycling, and i'll work harder on staying in Z2 to make the easy stuff both easier and more productive... and i'll do just enough swimming to get around without drowning or worrying about the cutoff... I'm also making the most of this 'year off' to build base fitness, and work on a few weaknesses.... it'll be nice to go into a training schedule feeling fighting fit, rather than worrying about survival!
