Of all sports, swimming probably comes closest to providing the most all-over fitness. Deep-water running, stair-climbing and cross-country skiing are the closest to running in terms of muscle groups used and range of motion.

- Biking

- Soccer
- Water running

Just be careful not to overdo it. Reduce your running to accomodate any new activities. Overtraining is overtraining, whether it's in one sport or a combination of them. Some of these activities may work muscle groups that you don't often use, or at least to a degree you're not used to. Ease into them gently and be sure to stretch beforehand. Just as you did when you first started running, be conservative and increase your effort gradually. As long as you keep this in mind, you can also consider cross-training days to be rest days for recovery from running. On the day after a race or a long run, try taking a spin on your bike or swimming a few laps instead of going on an easy run. Your aching muscles and joints will thank you for the break from their normal pounding.
