DORBA's Endurance Challenge at Northshore

3/7/24 Update: Trail is currently closed and more rain is expected. We are shifting the event to an alternate date of 6/8/24. Registered riders will receive details via email.

How far can you go? Formats to fit every checkbox for personal achievement and satisfaction! Side by side racing for those who need a competitive fix or solo Challenge format for those who only need to prove it to themselves.

Please note that signup is online via this website ONLY. We will not have on site registration. Slots will be limited and signup closes Friday night before the event.

Format Overview:

Challenge Format is for those looking to see how far they can go prior to the cutoff time. Each lap will be 10(ish) miles and there is a firm cutoff of 8 hours for up to 5 laps. Each Challenge rider will receive accomplishment recognition for each lap starting at 3 laps. How many can you collect? The Challenge format is NOT a race. Results will only reflect total distance/laps completed. They will not be ranked by time.

Endurance Race Format is for those who want to see how they stack up with others who are more oriented to side by side competition. 3 Lap and 5 Lap options for both Men and Women. Racers will also earn Challenge tokens but will not have their results mixed in with Challenge riders.

Awards for top 3 Overall, Top 25% Female (Up to 3 awards), Top 25% Single Speed (Up to 3 awards). Additional awards categories such as age breaks could be added if number of registrations prior to 3/1/24 allow for it.

Beginner Racer/Junior Racer 1 lap sprint race. This is a 10(ish) mile unsupported lap. Beginner racers should be true beginner racers who have not raced mountain bikes previously. Experienced racers should attempt the Endurance distance and build that skillset. Junior racers must be capable racers able to navigate a 10 mile loop on their own without support. This is not a Kidz Kup race.

Awards categories to be determined by age and gender based on signups prior to 3/1/24.

10 Mile Lap Details
Loops 1,2,5. Calibrated wheel sensor data confirms this as a 10 mile lap despite what maps say.
