Firstly, I would like to point out that I didn't sign up for a marathon to lose weight. I signed up because I want to run it. Losing weight is a separate issue.
Is it possible to do it though? Has anyone done it? How??
I ran a half marathon last year, and I don't think I lost any weight until after the race. Although I think I looked slimmer...
I would just like to hear of other people's experiences and any tips/ideas if you managed to do both.
