Points (Jun 4 2026): Mountain - XC (May 6 2025):						233.08 398.38		Upgrade Points: [show] Estimated USAC Upgrade points: (Assuming every race they've done was USAC-sanctioned, and everyone they raced was in their category -- i.e. this is a high estimate) Voluntary Upgrade Points (last 36 months): 93 Mandatory Upgrade Points (last 12 months): 33

Points in bold are being considered for the current points.
Points in italics are being ignored because they were your second race that day.
Green points are the best five races in the last 12 months -- the average of these are your current points.

* - Upgrade points make some assumptions about what category the race was (different categories have different minimum racer requirements and point structures). Points are based off of information found here. As with any other metadata on this site, this information should be used as a guide, not a definitive source -- for upgrade questions, please contact your local USA Cycling representative. Upgrade points from more than three years ago appear in italics and are excluded from calculations.
