In this week's Freetrail Subscriber Pod, Dylan and Travis delve into the world of performance index scores focusing on the ITRA and UTMB systems - a topic that has become increasingly salient in the sport.   We talk about the complexities of performance indexes in trail running, the history, significance, and calculation methods of these indexes, as well as the challenges and limitations they present for athletes. We also discuss the importance of transparency and trust in these systems and provide suggestions for future improvement.   Thanks for your continued support of Freetrail!
