How Cold Should A Person Go?

We recently were informed Big Shoulder's 5K OW is likely to be cold this year. (60-63) Due to a very warm summer in central Indiana most of my training was done in water 85-88 degrees warm. This week-end we got a break and out water has been 72 in the pool. (It feels so good!) My question is how much lower to what I'm used to can I go and be safe? I am 5'5" and weigh 117. I have done BS 5K in water as cold as 68 with no problem but I'm just not sure where to draw the line and bail into a wetsuit. I do not want to get hypothermia. I'm planning to be in the water somewhere between 1:20-1:30. :coffee:

  • ...On the other hand I saw a number of people including much better swimmers than I shaking and shivering. We all have different metabolisms and body types So while I now believe I could swim in water temps inthe 50's with some prep, others may find sub 70 a challenge.For sure, my experience was different -- fine for 1 mile in 62-65, but 3 miles was too long: forums.usms.org/blog.php.
