You are racing your competitors, not the clock.

It's a different thing whether to keep going to races, but I've always loved racing.

I believe 100 per cent in continued running after 40, and racing too, if one so desires.

Resting your body and legs in particular can lead to more effective running/racing.

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