Rebuilding distance question

Are you able to ride on a trainer?  The bike seems like it may be a bit of a lower impact way to get the HR up instead of the pounding of running.

How about run/walk intervals? That should keep the heart rate under control and allow you to spend some more time on your feet allowing your body to adapt.

I have an impressive collection of Ti in my wrists. Running hurt like hell for MANY weeks afterward. I put my aero bars on the bike, mounted the bike to a stationary trainer and went at it. No stress to the damaged wing at all. Next I started a water aerobics/ stretching/resistance training program. Open your palm and push/pull it through the water. Strength and flexibility in the damaged area has to come first. Running was the last thing I could do pain free-and that took me holding a tennis ball in my hands to absorb some of the vibrations. It's a long, slow process I'm afraid. Good luck with the mending.

I do have my tri bike on the trainer, just wanting to run so I can catch some 10k's or something before the end of the year.
