Instead of Running (679 calories at a pace of 11 minutes per mile)...
Try Ultimate Frisbee (572 calories)
In high school or college, did you view running as a necessary evil and a way to warm up for a more exciting team sport? Then seek out Ultimate Frisbee pickup games in your area (more info at USAUltimate.org). This self-officiated sport is similar to rugby played with a Frisbee instead of a ball, and tends to draw laid-back, social types who prioritize friendly competition over personal records. Leagues are usually welcoming to newcomers, but coordination is key, so you might want to play a few games with your dog—or your kids—first.
