Aw, man! Been just over a year since surgery. Forgot how great it feels to run. Been 6 years since I ran. Last two weeks I started with a couple minutes of easy running with a minute off, adding minutes to it. Totaling 20 minutes or so. Today, 13 minutes no stop. Could have gone much longer but I am being so cautious. CANNOT BELIEVE HOW GOOD I FEEL. Surfing sites for trail races in the spring. Have to say the existence of this site is what gave me the courage to get the thing done, and I am so glad I did.
