COURSE MAPS
Don’t let the distance fool you, you’re gonna work for this one! These XCO courses are punchy, fast, and spectator friendly. Racers will be coming through the start/finish perimeter area and be on trails easily accessible for viewing and pictures. So, bring your family and friends to root you on!
- March MudMess - This course is a blazing fast ~3 miles with ~310’ of elevation gain per lap: MMM COURSE MAP
- Escape Leakes Mill – This is the XCO course that started it all at ~3 miles with ~320’ of elevation gain per lap: LMP COURSE MAP
- Battle on the Ridge - New for 2026, expect this XCO course to be a burner at ~4 miles with ~510’ of elevation gain per lap: COURSE MAP - Coming soon!
- Punch the Unicorn – This XCO course is NOT for the faint of heart with ~3 miles and ~525’ of elevation gain per lap, it’s out to crush your soul: PTU COURSE MAP
Underground Series Championship Eligibility & Points
- This is a “most races, best places” series - ALL races count, no drops.
- You MUST race 3 events to be eligible for Series Champion Status.
- You MUST race in the same category for ALL races - places/points do not transfer between categories.
- Making it to the line counts - DNFs will still receive series points (seeded to back of field).
- 1st place series winners will earn Champion Status and this year’s version of the coveted RVA Underground Champion’s Jersey!
Pro Tip: Series races are as much about “showing up” as placing because even DNF’s receive points. We’ve seen more than a couple “upsets” happen on race #4 just because that person made that last race.
Junior Categories
- Categories are designed to allow juniors to compete based on ability.
- There is NO minimum age requirement. But common-sense rules apply for safety of all racers on course.
- Juniors will be competing on courses with adults.
- ALL junior racers MUST be on adult-sized bicycles (e.g., 27.5 or 29 platforms).

- ALL racers are encouraged to register for the category that best aligns to their ability as long as they are compliant with the category age determinate (U23, U19, U16).
