Running can def. make it worse. You are weight bearing and there are muscles that are working against gravity which you might not be using when you ride and thus, they don't hurt when we ride!

I was under the impression that my cycling was making my legs strong. I dropped weight training last September due to lack of time...

Last October I crammed my foot between two rocks while cutting my teeth on my new found New England trails. It didn't really 'hurt' but sometimes it felt like my foot was broken. I put it off thinking if it was a stress fracture it would heal on it's own like they have before. Well in April I decided I wanted to start to run. HAHAHHAHA...NOOOOO...so I went to my doctor, who sent me to PT.

Guess what? If I had kept up with my weight training, chances are it would of resolved itself. Now I have posterior tibialis tendonitis that I can't shake.

And worst of all...they told me yesterday I can't ride for a week. And if that doesn't reduce the inflammation, I may have to get a cast and keep off of it for a few months. NOOOO...

Moral of the story: If you get injured, get it checked out if it's bothering you. And second, don't stop strength training because you think you are getting enough weight training from riding. Especially 'balance' activities. You would be really surprised at how untrained you are from just working in the sagittal plane most of the time (ie flex/extension from riding). I think if I had to choose weight training vs balance- I would pick the balance part. This is where I really learned how messed up I was!

Good luck with your appointment. You will heal much faster addressing it now than later!
