Lately, I’ve been running in a lot of road races in preparation for the World Marathon Challenge (in fact, when you read this, I'll be a week from landing in Antarctica for the first of seven marathons). I haven’t participated in this many races in such a short period of time in 20 years. Back then, however, I was running fairly well, like in the 6-minutes per mile range. Now I’m closer to 7-minutes or even 8-minutes a mile. It’s a different experience running with the masses versus running closer toward the front with the faster and more competitive folks.
