Age 50 is a lot tougher than 40s

My biggest weakness as a endurance athlete has been in not drinking enough water after training, thereby racing sometimes while dehydrated.

Good health, peace of mind, being outdoors, camaraderie - those are all wonderful things that come to you when running. But for me, the real pull of running - the proverbial icing on the cake - has always been racing.
