Well, you now have a better choice to consider. Credit this breakthrough to horse trainers. An astute trainer found that by equipping a thoroughbred with flotation devices, the animal could run in deep water, and maintain conditioning while avoiding the impact of running on land. Many runners have discovered the benefits of pool running during injury. Olympian Mary Slaney set a U.S.record in the 3,000 meters immediately after a month's pool running.
Many athletes make it a part of their workout program after regaining full health.
It's a great change of pace. To be a pool runner you need a flotation device and water deep enough so you can't touch bottom. Equipment can be found in Pool or Running Shops, as well as in Catalogues. I opted for a belt and it has worked fine. However, bigger body types might need the additional support of a vest.
