About This Event
Set in the rolling hills of Tuscany's renowned Chianti wine region, this UTMB World Series event offers runners a distinctive blend of athletic challenge and Italian cultural immersion. The races wind through medieval castles, historic vineyards, and traditional Tuscan villages, creating a backdrop that feels more like a Renaissance painting than a typical trail running venue. Held in spring when the Chianti hills come alive with fresh growth and mild temperatures, the event centers around the medieval town of Radda in Chianti. Runners traverse a landscape shaped by centuries of winemaking tradition, passing through terraced vineyards and olive groves while navigating the region's characteristic undulating terrain. The race village atmosphere captures the convivial spirit of Italian hospitality, with local food and wine celebrating the finish of each distance. As part of the UTMB World Series, the event maintains international racing standards while embracing the unique character of its Tuscan setting. The Running Stones points system allows qualifying performances for UTMB Mont-Blanc, making this both a destination race and a stepping stone for runners pursuing the sport's most prestigious ultra-distance events.

The course explores the agricultural landscape surrounding Radda in Chianti, moving through the patchwork of vineyards, woodlands, and olive groves that define this wine-producing region. Runners can expect mixed terrain typical of Tuscan farmland, including dirt roads connecting estates, vineyard access paths, and forest trails through the oak and chestnut woods that separate cultivated areas. The route likely incorporates sections of the region's white roads, the unpaved limestone tracks called strade bianche that historically connected farms and villages across central Italy. Specific routing details and cumulative elevation are not published in advance. Runners should prepare for variable footing including compact dirt, loose gravel, and potentially muddy conditions depending on spring weather patterns.

The route departs Radda in Chianti and explores the forested hills and agricultural valleys that define central Tuscany. Trails pass through working vineyards where spring pruning is still underway, cross oak and chestnut forests, and touch on hamlets like Volpaia and Vertine that date to medieval times. The terrain switches frequently between maintained vineyard access roads and narrower woodland paths, with stream crossings and stone staircases adding technical variety. While complete course details remain subject to annual confirmation, the mixed terrain designation reflects the characteristic Chianti landscape: neither purely technical mountain running nor groomed trail racing, but rather a shifting combination that requires attention throughout. Navigation follows standard trail markings with course marshals at key junctions, though runners should expect some exposure to vehicle-accessible roads during village passages.
