Why is the non-wetsuit category called "bioprene category"?
This news article mentions "bioprene category" to mean non-wetsuit in the marathon swimming race last weekend.
I feel this word is very offensive to me, as I think it implies everyone swimming non-wetsuit is fat. Is it really true that you have to be fat in order to do non-wetsuit marathon swimming in cold water? (although that race was not cold this year despite the name - 18°C)
Moreover, can anyone give me advice for me to reduce fat and weight, while training for marathon swimming in cold water (targeting 15 km in channel temperature)? I am 174 cm, 67 kg and 17% body fat as measured by a bathroom scale, and I want to get 5 kg off my weight to around 62 kg, which was my weight when I was the fittest in running 2.5 years ago (but it was a pity that I wasn't swimming well at that time). I want to have as little bioprene as possible when racing OW swimming / aquathon / running / orienteering!
P.S. The coldest water I have access depends on the weather - this year may only be 18°C, but in some years it may be 15°C.
