I have always had a difficult time loosing weight at the same time as I increase distance. Years ago, when I trained for my one and only marathon, I gained a few pounds as my runs became longer.
I also want to train to ride a century, but for now, I need to get the weight off first, so I am focusing on that and doing shorter and more intense rides. (However, I am new to riding.) When I am down another 20lbs, then I plan on ramping up the miles.
However, this may be different for others.
