How Far Will You Go? UK's Biggest 24hr Trail Race

The UTMB World Series has announced a schedule of 35 races for the 2023 edition.

After its first edition in 2022, the UTMB World Series has increased the number of races up from 25 to 35 with first-time events in Africa and South America along with expansion in Europe, Asia and North America.

By competing at UTMB World Series events, competitors will earn a certain number of ‘Running Stones’ which are then used to enter the lottery for the UTMB World Series Finals at the UTMB Mont-Blanc.

New races

UTMB 2023 schedule
The 35-race calendar for 2023

There are 10 new races on the 2023 calendar compared to the year previous: Tarawera Ultramarathon by UTMB (New Zealand), Amazean Jungle Thailand by UTMB (Thailand), Ultra-Trail Ninghai by UTMB (China), Trail Alsace Grand Est by UTMB, Paraty Brazil by UTMB (Brazil), Valhöll Argentina by UTMB (Argentina), the KAT100 by UTMB (Austria), Mountain Ultra-Trail by UTMB (South Africa), TransJeju by UTMB (South Korea), Desert RATS™ Trail Running Festival by UTMB (USA) and Grindstone Trail Running Festival by UTMB (USA).

It means the world series now takes place on five continents.

UTMB World Series Finals

The UTMB World Series Finals will take place at UTMB Mont-Blanc between August 28 – September 3 in 2023, with races over a number of distances including the big three: 50K OCC, 100K CCC and the legendary 100-mile Ultra-Trail du Mont-Blanc.

To qualify for the UTMB World Series Finals, runners must finish in the top three (both male and female) of their respective category at any UTMB World Series Event over the 50K, 100K or 100M distance.

Runners can also qualify by finishing in the top ten of the respective category at a UTMB World Series Major. The 2023 European major will be Val d’Aran by UTMB, the American major will be The Canyons Endurance Runs by UTMB and Doi Inthanon Thailand by UTMB will be the Asia-Pacific major.

Qualification can also be achieved via a lottery, with entry to the lottery requiring at least one running stone – achieved by completing a UTMB World Series Event or UTMB World Series Major. At a Major, double the usual running stones are on offer to race finishers.
