You're running!? Awesome :-D [and yeah, your coach is super fast; she won 5Peaks this past weekend!]
hahahaha, she is awesome! :)
I am running, the trails do not seem to hurt me!! But i have to keep my butt training up!
haha
I find the trails easier on my legs than the road, if anything the constant changing stride and muscles hit. (And yes, keep it up :-) )
