A trail racing series featuring some of the most iconic sub-ultra trail races in New Hampshire is returning for its second year in 2025.
The White Mountain Endurance Cup from Aravaipa Running challenges trail runners to take part in at least three of four trail races in the White Mountains.
The series kicks off with the Chocorua Mountain 25K on June 7. It continues during the summer with the Baldface Scramble 29K on July 26 and the Jigger Johnson 20 Mile on August 16. It then wraps up with the Kilkenny Ridge 25K on September 20.
Participants need to finish three of the four events to be counted in the series standings. Only a participant’s best three results will be considered in the scoring.
Points are awarded based on a runner’s time as a percentage of the race winner’s time. The race winner receives the maximum points (100), and other runners receive a percentage of that maximum.
Men and women are scored separately in their divisions based on the winning time in their division.
Everyone who completes at least three events will receive a White Mountain Endurance Cup medal. Podium finishers will receive prize packs from Adidas Terrex.
The highest overall male and female scorers based on series points will be crowned King and Queen of the White Mountains and will receive invitations to join the Aravaipa Northeast Racing Team for 2026.
Participants can register for each race individually, or they can commit to all four at once by signing up for the 2025 series pass.
