I am reading a really great book on recovery by Sage Rountree titled The Athlete's Guide to Recovery. It a FANTASTIC book about how we all must stop and listen to our bodies especially when it comes to recovery from races and training runs. Because each of us enters our running journey at various fitness levels, age, weight, etc, our recovery times will vary.
That being said a 13 mile run is very taxing on the body. See how you feel today and if you aren't keeping a log, now would be the time to do so. It will become a valuable tool in your running journey.
RUN SPARK STRONG!
