Low body fat = warm during swim?
Just looking for tips how to prolong my swims in cold water. Coming from a triathlon background = skinny enough and I don't want to gain weight. Like I last maybe 40-45min in 11-12C so any longer ow swims has been put off. In a wetsuit in the same temp i would last +3hours easily.
To date I've received 3 tips:
Higher stroke rate
Keep at it and acclimatize
I don't want to go back to wetsuit and a layer of grease is a myth due to the thermal conductivity of fats/oils/greases is in the same range as human tissues.
Is that it? Or Maybe I should just move to Barbados or something!
