Consider running on grass. Also consider running hill sprints rather than short track sprints.
The wise people who run faster than I do tell me that these are good ways to avoid injury and lay the groundwork for good conditioning and speed.[/quote]
Running on grass works, it is also a harder workout from a cardio point of view as you can’t run as efficiently because of the softer surface, sort of a lesser effect than running in sand. I have a bad right knee and have found that I can do sprints on grass quite effectively with no side effects. The few times I have tried doing hill sprints on a road I noticed an immediate difference, so I’ll be limiting my hard surface running to slow jogs.
Try CT’s Interval Build Up Running described in his Running Man article. It’s a good way to build up to running harder intervals as you have to treat the whole 15 minutes more like a long distance run and the “sprints” end up up being more like a fast jog at the end of the session, so it is not too stressful on the body.
