The Canyons Endurance Runs by UTMB: Route, live tracking & how to enter

Last Updated

The Canyons Endurance Runs by UTMB is a set of UTMB World Series races taking place in the historic town of Auburn, California in the United States.  

Not just a qualifier for the UTMB World Series Finals, the legendary Ultra-Trail du Mont-Blanc (UTMB), but the Canyons Endurance Runs also has Golden Tickets on offer for the iconic Western States. 

The event also acts as the UTMB World Series Major for America, meaning finishers earn double the number of running stones and therefore more opportunities to qualify for UTMB. 

Date, start time & live tracking 

The 2023 edition of The Canyons Endurance Runs starts with the 100M which begins at 9am Pacific Time on Saturday April 29. 

It will have a 32-hour cut off time, meaning the last finisher must have crossed the line at 5pm on April 30. 

The 100K race will begin at 5am on Saturday April 29, with the 50K starting an hour later and the 25K race an hour after that at 7am. 

All the races will be available on the UTMB live tracking website:

The Canyons Endurance Runs 100M race takes runners across a gruelling but beautiful 100miles, including at least 5,181m of elevation gain. 

The race begins and ends in downtown Auburn – as do all the races- and includes part of the Western States Trail, the K2-climb, the American River and the foothills of the Sierra Nevada Mountains. 

Canyons Endurance Runs 100K takes in much of the same route, but with ‘only’ 3,200m of elevation.  

The 50K takes runners to the Foresthill Divide Loop amidst stunning scenery and has 1,706m of elevation gain, while the 25K features just 853m of elevation gain taking runners to the top of Lake Clementine.

UTMB Running stones and Western States qualification 

As the Americas UTMB Major, all running stones given to The Canyons Endurance Runs by UTMB are doubled. 

The 100M therefore gives eight running stones and 100K finishers get six while four are on offer for the 50K and two for the 25K. 

Ahead of the 2023 edition, Race Director, Charles Sheya, said he is looking forward to welcoming runners to California to experience the stunning routes as they seek UTMB qualification. 

“We’re thrilled to be welcoming the very first UTMB World Series Major in the US,” he said. “It’s a fantastic opportunity for all runners to increase their chances to be part of the Finals at Chamonix. 

“With a new exciting re-routes this year and hosting a departure and finish line at the same location, we’re excited for a festival atmosphere, with the crowd gathered in one place to support and encourage the participants to take part in this adventure.” 

The Canyons Endurance Runs by UTMB is also a Golden Ticket Race for the 2023 Western States Endurance Run (WSER), with the top two men and women finishers in each distance winning their place on the start line. 

The race is also a qualifier for WSER 2024, with runners who complete the 100-mile distance in under 32 hours and the 100K in 18 hours qualifying for the 2024 WSER lottery.

Who is taking part at Canyons Endurance 2023? 

The men’s 50k race is of keen interest, with US runner Hayden Hawks – who came second at the Tarawera Ultramarathon by UTMB this year – facing Britain’s Tom Evans who came third at the 2022 UTMB. 

Brazil’s Manuela Vilaseca will be looking to earn a first race win of the season in the women’s 100M field, while Sebastien Spehler will want to pick up victory in the 100K. 

Left-leg below-knee amputee Amy Palmiero-Winters will be tackling the 100M race. “I want to get out there and give it my all,” she said. 

“I want to cross that line and gather those Running Stones and get to the UTMB World Series Finals.”
