I once read (or I was told, can’t remember) that tiredness after a race is usually delayed by 2, 3 days; sure enough, only today I feel the legs complaining for any single step after last weekend’s exploit.
Keep this in mind when you’re looking at the pictures of the Talking Turkey Race on locallyrun.com: it was probably only half way through and I was already hurting!
