Sorry about your back problem flaring up. First time I have heard that running can help a bad back. Hope things get better soon.
Yeah, several times (including the last day in WY in Sept), I've had this issue on the morning of an O-race, and then after the race, back is much better. Maybe I'll have to wait until this Saturday at the Presidio for that to happen.
Looks looked it happened again. You may be on to something.
A little sore again today due to a lot of sitting in the car, but yes, felt great (at least, my back did) after yesterday's race. Maybe we need to try to convince the world that running in an O-race is the cure for a bad back - would markedly increase attendance ;-)
I am doing publicity for the Pacheco meet. I will add that.
