Not sure if you heard, but I'm walking running the 2011 Bank of America Chicago Marathon!

Over the weekend, I ran a half marathon for the first time. 13.1 amazing miles. Or I should say about 10 amazing miles - I wish the pain of the last three on nobody.

When I was entering my final mile, I tried to remember what it was like to be the guy who couldn't even hit ONE mile without panting like crazy. Less than six months ago, I could barely make two miles. Now, I'm a half marathon runner.

What's that tired phrase? If I can do it, so can you!

But at the end of this weekend's run, I really started to doubt myself. My body hurt. Everywhere. My neck was sore. Hips, knees, calves....things I didn't even know could be in the pain were throbbing.

I figured this would be a good time to talk to some injury experts to find out what kinds of things can go wrong when training for a marathon, and how you can avoid them. I went to one of Athletico's 50+ locations in the area and talked to Lauren Hogan, a physical therapist who has run three marathons.

If you're feeling a bit more sore than usual, or like you might have an injury brewing, Athletico gives complimentary injury screenings. They'll put you on the treadmill and look at how you're running, then check out your posture and put you through a strength test. They picked out my sore hips right away and showed me a few techniques to help strengthen them.

My feature at Athletico will air on tonight's WGN News at 5pm. It will be posted here shortly after. If you'd like to check out Andersonville's Athletico, or any of the other spots in the area, check out their website HERE.
