I ran Disney 1/9/11 and am registered for ING Miami 1/30/11. I took a few days off to recover than started back with 4 miles @ 15 seconds slower than pace, followed by 11 at pace (8:15). Muscles and cardio feel great, tendons are a disaster. Tips for the next 2 weeks of training? Any harm in taking 1 or 2 weeks off before another 26.2?
I did this last Fall - Marine Corps followed by Philly. I did run between the two but nothing fast or particularly long. Note that I'm not as fast as you are but I'm not sure that's relevant. Take a look at the link below (Hal Higdon) and check out the "Two Weeks Between" section. (I think that's more where you're at than "Four weeks between".) Read it carefully. Note he says to concentrate on recovery, that you won't improve your fitness. Rather do what you can to recover, while still doing some running.
Ice those tendons. I did this last year. I made the mistake of not letting the inflammation go down b/w the two races (over reaching a bit). It made it a lot less enjoyable. It's definitely do-able, just pay attention to how you feel.
