I'd describe myself as running hot... But really it's just that at 17stone I have a lower (should that be higher?) volume to surface area ratio than smaller people.
Can get cold standing around and stuff, but if I go straight from a warm room to exercising, it would need to be well below zero for it to bother me.
Five minutes into running or cycling I will be dripping with sweat... With running anything more than shorts, a tshirt and gloves is uncomfortable, and ten minutes into a run I will need to take the gloves off. I'm not that fast a runner.
On the bike I wear long sleeves and leggings below say 6 degrees, didn't use gloves until five years ago at all, now I wear them all the time. For about ten minutes after a ride I will continue to drip with sweat.
It doesn't stop me so long as it's not hot and I can get enough liquid in me. Although balancing the right clothes for social situations and not turning up drenched is hard.
