Funny and handsome, actor Ryan Reynolds recently proved he's far more than your typical Hollywood man candy. He hit the streets last November and ran his first New York City marathon. We told you all about it back when it happened -- here and here. But we're still inspired by the guy, and we think after you read this, you might just want to hit the streets in your sneakers too.

Ryan raced to raise money for Michael J. Fox's Foundation for Parkinson's Research foundation, because Ryan's dad has suffered from the disease for 15 years. But he also did it to test himself physically. "Marathon running, for me, was the most controlled test of mettle that I could ever think of," Reynolds told Men's Health. "It's you against Darwin."

Reynolds was plenty fit before he started training for his marathon, but he discovered what many people who race already know -- having that long-term goal in your sights is a powerful motivator. Running with a purpose -- whether the purpose is the prize or the money you'll raise for charity -- is a great way to give your running or walking routine new life.

Kristen recently challenged us all -- runners, joggers, and walkers, alike -- to sign up for a race this year. I've got my eye on a 5K in May ... what about you?
