dave hagerdorn— my college track coach– dedicated, mentor, was testing shoes for new balance and the soles were not right and ended up hurting his knee. as to not loose his stamina in the down time took up mountain biking. hit a tree in the woods and broke his neck. rode out of the woods and to the hospital. with his halo on, still rode a stationary bike. i haven’t been on the track since 2001, yet i can still call him anytime for training help, or life help in general.
