i think most people know i do the run/walk intervals when i run. it’s a bit of a hit on the ego, the walking part, but, it does two things for me: makes running in general less excruciating, which in turn lets you go farther. i also find that more often than not, if i try and do a run where i don’t take walking breaks, my pace ends up being pretty close to what it would be if i had. the run/walk thing might be good for those starting from scratch, build up some muscles and distances. i’m not sure what everyone’s goals are for the race, i don’t know what mine are yet. but just thought i’d throw it out there.
