@willbeonceagain8 One of the biggest things is proper nutrition before a big endeavor. Before the 100, I gained 8 lbs. carbo-loading and drinking myself silly with water. You can also do amazing things through the ketogenic diet through mobilizing fat for fuel, however that is too much work for me. Sometimes the body cannot go on if proper nutrition is not adhered to the week leading up. That said, if you hit your maximum that is awesome. Now you have a gauge to use in order to set new goals. I myself had a similar moment 112 miles into a 230 mile bike race due to drinking beer and eating a half sandwich the day before. Fuel is so important. If you are interested in this race next July, it may be a good goal for you. It's through an organization called Ride For Water http://paul-joung.squarespace.com/
