I ran my first marathon one and a half weeks ago, a trail run. I felt great during and after the run. Next day I still felt great other than swollen IT band, which I was expecting. Only very minor muscle soreness and not at all tired or worn down. I even tried a little jogging the day after, while walking the dog, but my legs weren't quite ready. Three days after the race I decided to get back in the groove and run a few miles. When I tried to run I was completely out of breath, like I've never run before. I have to teach a couple hours of cardio kickboxing in the evenings and the same thing. We start to jump rope and I am panting! I wasn't too bothered by it at first, but now it has been 1 1/2 weeks and I'm ready to get moving at a decent pace, but can't. I ran a couple of miles today and was breathing like I was sprinting. Anyone ever have this happen? Any advice? This just sucks! I wanted to take some time off after this race, but not completely OFF! Any advice, encouragement would be appreciated.
