Jennifer Lopez and Matthew McConaughey in Malibu Triathlon

Tri It Like J Lo and Matthew

What do Jennifer Lopez and Matthew McConaughey have in common, besides their skintight matching outfits?

Both celebs participated in the Malibu Nautica Triathlon yesterday. The race benefits LA Children's Hospital and it make sense that two new parents would want to help a renowned pediatric hospital. This sprint distance triathlon is comprised of a half-mile swim, an 18-mile bike ride, and four mile run. The celebrity charity distances might be a little shorter, but J Lo and Matthew still jumped in the ocean, pedaled on a bike, and finished all that up with a run. A well rounded workout for a Sunday morning.

Having done a sprint triathlon recently, I guess I now have something in common with these celebs too. I must say, I think training for any kind of endurance race is a great motivator, but since triathlons are all about cross training, they're great for preventing overuse injuries. So I think you should try a tri if you haven't already. If you're looking for a race check out for race listings near you. And here's a training schedule you can follow.
