Dear Chaskis, How do I fuel for multiday runs and competitions? Can I rely on the trusty gas station stop to meet my nutritional needs? Sincerely, Aspiring multiday runners who finally found a time to catch up on their podcasts Part Four of our nutrition series brings us Chaski coach and crazy fast and accomplished multiday pro runner, Pete Kostelnick, with some nutritional guidance for multiday runs. Following suite with our previous fueling posts Fueling for 50K, Fueling for 50k to 100k, and Fueling for Ultras: 12-24 hours, Pete dives into nutritional best practices, timing, and strategy for long-haul runs. Pete is one of the most accomplished multi-day athletes in history. In 2016, Pete became the fastest person to run across the USA, covering 3067 miles in 42 days (72 miles per day avg). Always looking for more, he then became the first person to run from Alaska to Florida, covering the 5,384 mile journey in 98 days, entirely self-supported (i.e., he pushed a baby stroller with a tent/food/water/etc). Pete is also a stud at individual racings, having twice won the Badwater Ultramarathon and with a 100 mile PR of 14:04.
