About This Race

The 46K distance offers runners a substantial introduction to Chianti's challenging terrain without the full commitment of the longer ultras, making it an ideal progression for those stepping up from marathon distance or seeking a strong UTMB World Series qualifier. This distance captures the essence of Tuscan trail running through sustained climbs among the vineyards and medieval settlements, requiring steady pacing and hill-running fitness while remaining accessible to runners newer to ultra-distance racing. The course demands respect for Chianti's rolling topography but rewards finishers with a genuine ultra experience and valuable Running Stones points for future UTMB qualification.
