Want to lessen your chance of sports injury? Consider racewalking over running. There is a Kansas City organization always open to new members: the Heartland Racewalkers. They meet weekly on Saturday mornings at the Health Plus gym at 435 and Roe. Running puts more stress on the joints because all your weight (with momentum) lands on one leg. Racewalking requires both feet to be on the ground thus decreasing the force on the joints. For more information check their website: www.heartlandracewalkers.com .
