DNF - What went wrong?
I suffered the embarrassment of a DNF during an Olympic Distance swim recently and I'm trying to understand why and am hoping you guys can offer advice and pinpoint why.
I'm not unfit, although swimming is my weakest of the three disciplines. I run a sub 37 10k and typically finish a 40k bike in under 1:10 and was aiming for around a 30minute 1500m swim. I'm hoping (and praying) the problem is equipment related because I have my 'A' race for the season in just three weeks which is a 70.3, and naturally if it's fitness related 1900m is going to be near impossible to fix in three weeks if 1500m caused such a problem.
Four days before this race I went to a local 50m lido and swam a 1500m straight swim (30 lengths no wetsuit) in about 32mins relatively comfortably. So I know I can swim the distance.
On race day about 400m into the open water swim, my shoulders felt like they were on fire, like I was running uphill compared to everyone else. By the time I reached 600m, I was breaststroking, trying to catch my breath as everyone swam past, trying to muster the will-power to break back into a front crawl. Within 60 seconds of a crawl, my arms were again burning and I couldn't continue and started breaststroking again. So after the first lap I struggled over to the swim exit and got out a lap early and started unracking my bike.
I've narrowed the variables down between the 1500m effortless swim on Wednesday and the nightmare a few days later. The problem is either a)the wetsuit not fitting, b) the trisuit underneath being too tight (restricting my shoulders), 3) going off too fast (even though I felt controlled) or 4) lack of open water swimming. I thought wetsuits were supposed to make swimming easier!
I know it's hard to gauge via the internet, but I really need to rectify the problem before my 70.3 or it's a lot of time and effort down the drain. Tomorrow I'm heading to the lido again with my wetsuit and trisuit to see how I struggle again. But any similar experiences or advice would be most helpful.
