During each UTMB World Series Major event, a total of 210 spots are available for the UTMB® World Series Finals
These spots are evenly distributed among three race categories: 100M, 100K, 50K, with 70 spots for each. This allocation includes both elite and age group runners, and it's divided equally between men and women.
Additional Spots: The remaining bibs, out of the initial 35, are awarded to the next best-placed runners within their age groups. The exact allocation is determined by comparing the number of participants in each age category to the total number of runners in the race for each gender. This means some age groups may receive extra spots, while others may not receive any.
