I go through each item required by the UTMB regulations for the UTMB World Series Finals in Chamonix (UTMB, CCC, OCC, TDS, MCC, etc.) I show you exactly what you can or cannot use for each of these items and give you the best options possible to have the lightest and smallest bag possible. You will see how I was able to run UTMB in 2024 with a 5L bag that weights only 1.5kg. I took as basis the UTMB Chamonix rules, but this also applies to most trail running races (with minimal changes). This video is a must watch for any trail runner who wonders why elite athletes always have very small and light bags. #utmb #utmbworldseries #trailrunning #montblanc #chamonixmontblanc
