<human>: I'm a sophomore high school cross country athlete, by no means any good. In a race, my ankle began to hurt and after an X-ray and an MRI we figured out I have a stress reaction, which is basically a precursor to a stress fracture. I've been out for about a week and a half now, and I'm walking pain free, but according to the doctors I need to spend at least two more weeks without running. I'd love to be able to catch up once I come back in for the last two weeks of my season, since I left just as my (and my teammates) times were beginning to rise a **lot**. Does anyone have any good tips or exercises to me that could facilitate that?

Give me a shortened version of the text
<bot>: I'm injured and I need advice on how to properly stay in shape so I can come back not too far behind.
