So you don't think the surface you run on has any affect on your muscles? I ran a marathon (on trails) Saturday and except for a little stiffness in my calves on Sunday I'm pretty much back to 100% recovered.
I ran 5 easy miles on Sunday and ran for 75 minutes last night on the trails in Horse Hill. I feel great, stairs are not evil and nothing hurts.
Too bad the trail racing season just wrapped up with Stonecat....
