Mendelbaum!!! I didn't run last year because of a foot surgery but prior to that we ran all summer. Just takes a few weeks to ease back into it. The biggest thing for me for the first couple of runs is dealing with shin splints.
If you're getting shin splints:
- check your shoes aren't over worn and that they fit properly
- think about your gait, make sure you're not overstriding and heel striking
- don't run as far to start with, better to do short runs more frequently than long runs less frequently
Shin splints are caused by the lining between your calf and your tibia getting irritated - you want to reduce the impact and wear until your body gets back into the swing of things.
