Registration Closes March 16th!

What started as an elaborate shop ride has gained quite a bit of popularity. Our little event has steadily grown over the last few seasons because of the unique two bike format: every rider must bring a mountain bike and a gravel bike. You start the ride on one bike, then midway through, you must switch to your other bike. The whole concept of the Grountain Bike Challenge is to make the riders switch riding positions/bikes. Not only does it force the rider to tackle terrain that the given bike wasn’t intended for, but the change of position is equally liberating when the bike favors those conditions.

Due to the logistics required to run this kind of event, we’ve always limited the number of participants to a small amount. This helps us run a well-organized ride with maximum fun factor. This year we are opening it up to 75 riders because we have an amazing crew of volunteers to pull this off. 

Check out some video of our last grountain bike event!


    We have carefully planned out two routes to choose from; one “short route” and one “long route”. Riders must decide at the time of registration whether they want to go short or long without any foreknowledge of the routes. Participants will first ride counterclockwise on the route distance they chose. Then they must switch bikes and ride the same route clockwise. You get to choose which bike you want to start with!

    *You will get the actual STRAVA routes 1 week prior to the event! Make sure you provide an accurate email address to receive the STRAVA LINK. 


    Routes begin and end at the shop- JRA Bikes and Brew 215 E. Thousand Oaks Blvd., Thousand Oaks, CA 


    Short Route” is ~15 miles with 2200 feet of elevation gain. Total mileage for both laps is approximately 30 miles with 4400 feet of elevation gain. The short route has a good mix of riding terrain for both bikes. You can expect a little bit of everything, even a couple spots that will have you wondering what the hell we were thinking.


    Long Route” is ~20 miles with 3350 of elevation gain. Total mileage for both laps is approximately 40 miles with 6700 feet of elevation gain. The long route shouldn’t be taken lightly. The elevation and some of the technical factors more than make up for the mileage. Be ready to hurt. In a good way. If you’re a sadist. I mean a cyclist.


    But that’s not all! We have a little something extra thrown in to liven things up a bit. You’ll just have to wait until Sunday morning to see what we have in store for you. MWAHAHAHA!



    • This is NOT a race. It is a challenging ride to enjoy with your friends.
    • There are no categories but we do have awards for a few KOM and QOM segments.
    • All riders must bring two distinctly different bikes: a gravel bike and a mountain bike. See definitions below.
    • All riders must ride one course with their mountain bike and the other course on their gravel bike. The order is up to you.
    • E-bikes are not permitted for this event.



    • A gravel bike must have drop-bars and a max tire width of 47c. 
    • A mountain bike must be a hardtail or full suspension bike with flat or riser bars and a minimum tire width of 2.0”. 
    • You can run gears or singlespeed on either or both bikes. However, be prepared for some tough riding.
    • E-bikes are not permitted for this event.

    We hope you understand that we aren’t trying to be exclusive to those who don’t have two bikes that fit these requirements. The whole point of this event is to challenge everyone by taking you out of your comfort zone; to test your mettle.



    • A crazy day in the saddle, or should we say saddles, with an awesome support crew. 
    • Volunteers on course to cheer you on and so you don’t get lost. 
    • Mechanic support at two locations. 
    • Feed/hydration zone with Skratch Labs. 
    • Coffee in the morning before you roll out. Afterall, we are a bicycle AND a coffee shop. 
    • A hearty lunch by iHeart BBQ and ice cream from Kevin Hoard with SRAM. (You can purchase ADDITIONAL lunch tickets if you have someone coming to hang out afterwards) 
    • A swag bag with some cool mementos of the event. 
    • Prizes for the KOM and QOM segments. (We’ll announce KOM/QOM segments that morning. We don’t want anyone training to get those segments dialed in) 
    • Onsite bathrooms. 



    The fine folks at Pedals & Pints will be onsite for our beer garden from 12-4pm! Beer tickets are $4 each and must be purchased in advance on the registration page. We’re sorry, there will be no onsite beer sales. There’s a good chance you might be dehydrated so please remember to drink responsibly. 



    Registration closes March 16th. There will be NO ONSITE REGISTRATION. If you are unable to participate, you must cancel by March 16th to get a full refund. There will be a $20 cancellation fee if you cancel after March 16th to cover catering and accommodation fees.
