So I've been running between 8 and 12 miles daily but my left shin started hurting a few days ago. The day after I noticed it acting up the pain was too much for me to run on at all. I wound up getting sick so I took a few days off anyway. Started up again today and felt fine until tonight some time after my run. Shin splints? How long should I stay off it? I really didn't want to lose my edge, I was making real progress. I guess elliptical and swimming will have to do for now
Ice and stretch the calf. Strengthen the muscles with toe raises. (Seated, feet flat on floor, slowly raise your toes up keeping the heel on the ground. You should feel it in the shin. Calf raises work too- youtube them)
I find that after I run long distances at slower speeds, my legs tend to really hurt after even to the point of having to hobble a bit. Then again, I'm a bit of a noob at this point.
Mile sprints don't really impact me all that much at this point. I'm talking four or more miles.
Actually that make perfect sense. You've trained your "fast-twitch" muscles to work efficiently with all the fast running you've done. But when you run slow, you are recruiting those "slow twitch" muscles which haven't built up any endurance (yet). The intensity of the fast runs is too great for the "slow twitch" muscles to be stimulated optimally, so they lag behind. The intensity of the slow runs is too low to recruit the fast twitch muscles you've built up.
This is way variety of pace is the SINGLE best thing a runner can do to improve.
