It's only been a little over 2 weeks, but my recovery from the Houston Marathon is coming along fairly well. The soreness is long gone and the only remaining problem is that it takes a lot of effort to run at a pace that used to be fairly easy. I ran 14 miles on Sunday and 6 miles yesterday and am actually now in the taper period for the Austin Marathon on February 17. Hopefully between now and then my muscles will fully recover and I'll be able to have a good race.
The following link shows an elite female runner at the end of her first marathon. It's a distance that can humble even the best and the fact that she can barely move her feet is shown by the fact that she falls 3 times in the last 300m of the race, the last time less than 10m from the finish line.
