About This Race

The 21K serves as an ideal introduction to the challenging Chianti terrain, offering runners their first taste of Tuscany's relentless rolling hills without the extended grind of the longer distances. This half-marathon distance allows runners to experience the region's signature vineyard climbs and technical descents while maintaining a manageable time commitment, making it perfect for those new to trail running or seeking a spirited workout amid the medieval landscape. The shorter format means less navigation complexity and more opportunities to appreciate the cultural details along the route, from ancient stone walls to traditional farmhouses dotting the hillsides.
