I was googling Rice's workouts and found the Hill workout. Since this was posted, I found more info on it:
The man who found the Hill to begin with was his orthopedic surgeon. Apparently it's a little bit complicated to run, as it involves quite a few turns.
Among the challenges of running The Hill is finding it in the first place. It's tucked away at the corner of Edgewood Drive and Old Stage Coach Road in Redwood City. Craig, now a veteran of several marathons and half-marathons, has run the trail so many times that he does it by memory, not maps, so his directions tend to be esoteric. "Watch for this tree. There'll be a little slope to the left. Don't take any of the switchbacks."
