sk - I'm a size 7. What are these magical socks you speak of?

mp - I think the course is the same, we start in Union Square, head out to Embarcadero, travel 'round to the Great Highway and end at GG Park. So tell me how many hills we hit....

I'll check out the links KSH, thanks!

jvm - I'm doing the Nike Women's Marathon - walking the 1/2 on October 19.
