From the Organizer
The Summer Series is where it all started and to this day continues to be the staple of the Quick n’ Dirty vibe. You can expect a fun, fast, and challenging series of races that keeps you tuned up, doesn’t break your wallet, and in most cases, gets you home in time for dinner. However, we will have food vendors on site if you want to kick back, relax, and grab a bite to eat at the race.

From Endurance Grid
Endurance Grid is here to help you understand the sport, decide if it’s the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer’s event page.
Mountain biking takes place on singletrack and natural terrain where reading the trail matters as much as fitness — cornering, braking, and instinct on dirt are skills that only come from time in the saddle.
Events range from beginner-friendly cross-country races to technical enduros, and the trail community is one of the most welcoming in endurance sport.
XC races, enduros, and fat bike events across U.S. trails. Technical, physical, and completely different from anything on pavement.
