Eventually, competition and adventure wane, and I enter my ibuprofen phase. Tweak hamstrings and achy knees restrict mileage, but I continue running for health, sanity, and the ritual of a Sunday trail run with like-minded buddies. We discuss the nagging injuries that bedevil us, and remember the good old days when we were kings.
