So… the 2012 Boston Marathon was epic. I heard that more than 4,000 runners took the BAA up on their offer to defer until next year. These are probably fast runners who wanted to go for PRs (personal records). Smart folks. Another 2,000 or so did require medical help of some kind, and they included elite and expert runners.
The BAA warning before the race was pointed: If you had never run a marathon or had not run in these conditions, they recommended you bag. I realized if I ran in the 88 degree heat, next time that warning wouldn’t mean me!
