I normally drink about a pint of water before setting off on say a 30mile journey, another half a bottle on route and about a pint when I finish.
I find it a good idea to load up on water before I go but not to drink to much on route. -
Ive always been a sweaty betty , on battlemarches the other guys would come in looking a bit flushed , me I looked like I was dragged through a hedge backwards and had a bucket of water tiped over me head.
having said that I,m not busting a gut out thier, on my exercise bike it looks like I,m melting.
