I can honestly say in my 24 marathon finishes (these include races, pacing, and a few trail marathons), that I have never been a victim of the infamous marathon bonk. The closest I have ever come was at the Cincinnati Flying Pig in 2007. For whatever reason that day I did some really stupid things with my nutrition and suffered major stomach issues after the race. I remember hitting some tiny incline around mile 24 and after having been on pace for my goal all day I watched it slip away.
Determined not to let that happen again, I researched like crazy and devised a nutrition plan based on the information I found. Because I’m a big geek, I came up with a mathematical formula to calculate exactly how many calories one needs to take in during the marathon to prevent bonking and minimize GI distress.
Are you ready to see how many calories my magic math says you need to take in per hour of your next marathon? Well get your calculators and come along and see!
