In reply to Eric the Red:
I used to run heavily as well, 70-80 miles a week on average - not training for a marathon or anything, I just loved running, trying to stay in shape and keeping myself sane waiting for the summer to head off to the hills.
Last Feb, I messed up a bunch of ligaments in my right foot. I couldn't run at all for months... I still did my best to stay in shape in other ways but completely lost my mojo as well even when I began to actually be able to use the foot again.
I climbed on a aching right foot all summer, then only recently found the urge to get back into "training". - still can't / or don't want to run like I used to. A bunch of us staff here are doing some gym jones/cross training/p90x type workout circuts, they're really motivating and fun.
Realized that I'm just completely burnt out from running and only this past week I was able to go for a 2 hour run for the first time since my injury.
