Team Classification: We’re adding a team classification for the overall series. The standings will take into account your top five riders. Note: at least two must be women.
More info info below under “How does Team Classification work for the Series overall?”
Group Discounts:
Groups of 5 or more receive $10 off per rider. Message us for your custom team/group code.

Low Gap Course Update: Low Gap now offers two course options, a short course and a long course with the same great finish and post event party.
Junior Series: Juniors now have their own series. To be placed in the series results, juniors must compete in three (3) of the (5) five events, including the Series Finale at the Ukiah-Mendo Gravel Epic. Junior competing for the Overall Series MUST ride the short course for Low Gap, Huffmaster and King Ridge. At Ukiah Mendo Epic they will race the Mediano and at Jackson Forest will do one 25 mi. lap.

Series Overall Podiums: We’re expanding to a Top 5 podium for overall series results for every category.
Event Podiums: Each event will now feature a Top 5 podium for Pro Men and Pro Women categories. Age groups are top 3. Short course podium for top 3 M/W Overall, not per age group. Also, U16 and 16-18 top 3 M/W.

Yes! It’s up to you. These aren’t your average events; they’re adventures that push your boundaries and inspire independence. Some riders push for their best finish, while others are there simply to enjoy some really cool places on two wheels. We have a podium for the top 3 finishers in all categories and cash prizes for the top 3 Pro M/W, but if you’re just in it for adventure and exploration, we say ride on.

Note: All Hopper routes are open and riders must obey all traffic laws and rules

Hoppers are what you make of them. Riders are welcome to simply join individual events, or test their mettle in the Series Overall Podium.

Series Overall Podium
The Series Overall Podium is calculated using a point system. Placing in each series event awards you points in the following manner:

1st place = 60 points
2nd place = 55 points
3rd place = 51 points
4th place = 48 points
5th place = 46 points
Each place after 5th earns one less point than the place above it (i.e., 6th place = 45 pts, 7th place = 44 pts, and so on).

Overall Points Leaders will be calculated by adding up place points in each event completed. Only your top 4 finishes will count towards your Overall Points. If you complete all 5 events in the series, your lowest result will be dropped.

Overall points are only awarded to those who complete the long course options at Low Gap, Huffmaster, King Ridge, Jackson Forest and Ukiah-Mendo Epic. For each event that has a long course option, riders competing for the overall series podium MUST ride the long course.

In order to be eligible for the Series Overall Podium, (aka “Hopper Super Hero King, Queen and Rider of the Universe”), riders must contest King Ridge, the series finale, on May 10.

Overall winners for all categories will win a free Series Pass entry into next year’s Grasshopper Adventure Series.

Junior Series

The Grasshopper Junior Series gives young riders the chance to experience the challenge, adventure, and camaraderie of the Grasshopper events in a fun, supportive, and competitive environment.

Race Format:

Juniors will compete on the Short Course at all events, except for the Ukiah Mendo Gravel Epic, where they’ll race the Medium Course.
To qualify for overall series standings, riders must complete at least 3 out of the 5 series events and be present at the series finale, the Ukiah Mendo Epic.
Junior riders who race 4 or 5 races, the top 3 finishes will be scored.

Age Categories:

Men’s U16 (Under 16)
Women’s U16 (Under 16)
Men’s 16–18
Women’s 16–18

Series Scoring & Awards:

Series points are based on each rider’s results at their eligible events.
The best 3 results will count toward the overall Junior Series standings.
Overall podiums will be awarded for each of the four age categories at the conclusion of the Ukiah Mendo Epic.

How to Register:

Junior riders can select their appropriate Junior Category during registration.
All junior participants must have a parent or guardian sign the event waiver.

The Junior Series is all about exploration, growth, and fun on the bike. Whether it’s your first Grasshopper or you’re chasing a series podium, you’ll be part of an incredible community of young riders pushing limits and having a blast.

Don’t Cross the Yellow Line

Stay in your lane! We have a permit to use the road, but that doesn’t exempt us from following traffic laws. No crossing the yellow line—otherwise known as the middle of the road!—even if the group swells or the pace slows. If there’s no yellow line, stay to the right.

All riders must obey the rules of the road.

Don’t Ride or Pass Aggressively

Grasshopper Adventure Series events are designed to challenge you. We've curated these routes with just the right balance of NorCal’s finest winding backroads, gravel paths, and dirt tracks. This is about adventure and camaraderie, but it also inspires independence. Not sure about your fitness, ability, or familiarity with the course? Here are some tips:

1. Pace yourself. Smooth before fast.
2. Study the course ahead of time, including the map, elevation, and terrain.
3. Bring essentials: extra tubes, tire boots, CO2 and a pump, food, water, warm clothes, a course map or GPS, space blanket, and a good-luck charm.
4. Make new friends, especially locals—they know the roads.

Obey traffic laws. The course is open, marked, and, where possible, pre-riding is encouraged.

SAG and Emergencies Only

We’ll have an EMT and SAG (Support and Gear) vehicles for injuries only. If you’re tired or cramping, you’ll need to make your own way back. Carry tubes, a pump (not just CO2), chain tools, and cash for food stops if needed. Water, hydration and snacks will be available at two rest stops, but bring your own extra fuel.

No Personal Support Vehicles

No personal SAG or follow vehicles allowed. We need to limit cars on the road. If you'd like to volunteer on the course to see what it’s all about, let us know. Volunteers earn entry to a future Grasshopper event.

No E-Bikes or Aero Bars*

If you drop out mid-course, have a friend notify us at the finish.

Lunch and cold drinks await all finishers!
