With all of the hot weather that we’ve been having, there has been some talk that IMUK might be a non wetsuit swim. This won’t happen. The organisers will take the temperature early in the morning and probably from a boat near the middle of Pennington Flash, just to make sure that the temperature is below the upper limit. In over 20 years of triathlons I have never done one where wetsuits were banned.
I’ve done some long swims, including Ironman, double ironman (here), triple ironman (here) and a 10k swim in Salford Quays where I ripped my wetsuit minutes before starting. The swim in Salford was on a very hot day, and I didn’t overheat in my wetsuit, although my drinks bottle almost melted.
But, if wetsuits are optional, should you go without?
I’m not the strongest swimmer or the most efficient, so for me it’s a no brainer. A couple of weeks ago at Isoman (read about it here), because I was only doing the swim I went without a wetsuit. I didn’t get cold, but I was seriously tired at the end of the 7+ mile swim and would have been much quicker if I’d been wearing my wetsuit.
I have raced once without a wetsuit. I did the Cockerham Triathlon in 2007, my first race after moving to Lancaster, and because the swim was less than 400m, the time I would have saved from wearing a wetsuit I would make up with not having to remove it. For me, if the swim is 500m and the water isn’t too cold, then I would possibly go without a wetsuit, but for all other races, I will be wearing one, no exceptions for me from now on.
