It all depends on the intensity of the race and how much it took out of you, as well you the individual, because we all recover at different rates. Ideally a day after the race you just want to go for a very slow recovery run, may be just for a mile or two miles. Nothing too streneous.It is unusual to run the same distance shortly after the race as during the race as the idea is to "Peak" in the race. You should eat as quickly after the run as you can so that the energy in your muscles is replenished as fast as possible. This aids recovery.
