• Age group placement earns additional points, with top finishers scoring up to 20 points (1st place) and down to 2 points (for 16th–20th).
• Overall podium winners (1st, 2nd, 3rd) earn double their age group points—for example, an overall 7.5 Mile winner scores 41 points!
• Volunteers are a huge part of race day too, earning 5 points each for their club.
• And because Prove It has two distances, the 10K is worth double points—making it a huge opportunity to rack up a big score for your team.

• All clubs who compete also earn points toward the Overall, 2026 Trivium Club Competition
• The Overall season winner will be treated to a club party and receive the club cup to proudly display for the next year!
