I'm slowly reintroducing my body back to running and it's going surprisingly well. It seems I'm getting back into the groove. My tendonitis is gone and it's starting to feel like spring (today it's a "warm" 45 degrees).
If you'll are considering getting (back) into running, now is as good a time to do it as ever. Today I've been on the phone trying to talk a couple of my kids into running the Flying Pig with me in May. Not the full marathon, of course. But if they start training now they can do the half. Wouldn't that be fun?
I know what you're thinking: "Dave, you're 100 years old. You need to be kicking back and watching the grass grow. You should be sitting in your warm living room, not out there running in the cold." But, see, that's the point! We dinosaurs run because it takes us out of our comfort zones and into the wild world around us. That's exactly why I love all these adventures I do. My advice to you -- don't ever stop stretching yourself. There's still a lot of adventure awaiting you. You will hate moments of it but you will love most of it, I guarantee you.
