Thaat was all, just a dunking in 58 degree water. .... By the time he reached us, at most 30 minutes later, he was hypothermic and getting quite shocky. I was scared shitless when I saw how grey and incapacitated he was. He had little or no muscle controll left and near violent trembles.
As much as age, I'll wager that his "marathoner physique" may not have helped him. Guessing he's slim/small muscle build with not much body fat. If he eats like a marathoner (low fat, high protein, low carb), I'd guess he wasn't running on a lot of excess calories or glycogen, either!
I don't know for sure what everyones' meal habits are, but the river is no time to cut calories. Fats are your friend to keep warm and keep hypothermia at bay (I've been mildly hypothermic 3x in my life, and EVERY time was tied to dehydration/low calorie stores). Now I eat like a beast before every river trip..you never know!

It makes me cold to look at somebody cold so I have learned to stop, make em walk around and gear up.
