What happens if you did the a half or full marathon yesterday?

If you did the half or full marathon yesterday, then great job! There is a downside to that though. You will be extrememly sore (as you can probably tell), you will need to take time off from running since you need a lot of time to recover from that, and your track season probably won't be as good as you might have wanted it to be. For the half, take atleast a week and a half off and for the full take atleast 3 weeks off. That may sound like a lot of time but it's what your body needs and is the only way that you can possibly complete half of your track season's goal. Rest any less than that and you will be in more pain and your body will defenitely not recover completely.
