Have you acclimated?: Running distance should not be attempted on the first outing. Depending on your cardiovascular conditioning, overall health &previous exercise history, it may be necessary to work up. Try running 1/2 mi every day for 2 weeks on a soft high school track, then progress by 1/4 mi every week, running 4 days a week. Distance running greatly increases joint injury risk &has no health benefits!

Running Tips: Long distance running takes time to build into. Start out with short distances and increase slowly. It's important to wear well - supportive running shoes with good insoles. I recommend getting fitted at a running shoe store for your best fit. This small step can dramatically affect all of your proximal joints!
