4 Jun - Jun 6, 2027
From the banks of the Tennessee River to the sandstone cliffs of Cloudland Canyon, the American South gets its first UTMB.
Ultra Trail Chattanooga by UTMB is the first UTMB World Series event ever held in the Southern United States, running from 4 to 6 June 2027 in Chattanooga, Tennessee. Its River to Clouds courses climb out of a downtown riverfront basecamp at Erlanger Park onto the ridgelines of Lookout Mountain, with the 100K finishing deep inside Cloudland Canyon State Park, over the line in northern Georgia. All three distances, 100K, 50K and 20K, award Running Stones.
Ultra Trail Chattanooga by UTMB brings the UTMB World Series to the American South for the very first time. Held from 4 to 6 June 2027, the inaugural edition sets its basecamp at Erlanger Park, the riverfront stadium in downtown Chattanooga, and pushes runners straight out of the city streets and onto the trails that have quietly made this corner of Tennessee one of the finest running grounds in the country.
The flagship 100K follows the River to Clouds route, a course that travels from one end to the other instead of looping home. It leaves the banks of the Tennessee River, climbs the flanks of Lookout Mountain through dense hardwood forest, links scenic ridgelines, sweeping overlooks and long stretches of technical singletrack, then crosses into northern Georgia to finish inside Cloudland Canyon State Park, among towering sandstone walls and cascading waterfalls. With roughly 2,400 metres of climbing, it is a race of relentless short ascents rather than one giant pass. The 50K and 20K stay closer to town, starting and finishing at Erlanger Park.
Chattanooga is North America's only National Park City, and the race carries that identity: it was built alongside the land trusts, trail crews and volunteer groups who look after these paths all year. Runners come for the terrain, for the warm Appalachian nights of early June and for the Running Stones that open the road to the UTMB World Series Finals; they stay for a Southern welcome that spills out of the aid stations and into the streets of downtown.
