I run in a fleece jumper and fleece hat, even at this time of the year. I have nothing on the lower half.
No that's not right, I wear shorts.
So I run hot, I get hot and I sweat - alot. I am under the impression that this is making my metabolism run harder and so I am burning more fat. Because I once heard from a bloke down the pub called Dave, who owned a spitfire, (so it must be true) that Robbie Williams used to train in a sweat suit. Or am I completly bonkers?
I will add that for runs which are likely to go for more than an hour and a half I run in only a t-shirt, and if my run is greater than about 7km I run with water.
Today I even went out in an anorak!
