We are 10 days away from the 2026 East Bay Dirt Classic! A few of us rode the course this past weekend, and it is riding very well. A couple of things to note:

1. The course this year has a slightly different route on Goldenrod, staying high instead of dropping down into Chuck’s Loop. This year’s course can be found here: 2026 East Bay Dirt Classic Course. Please make sure to update your GPX file if you plan to use your GPS device on the day of the event. We will also be marking the course and will have a volunteer at this spot to notify riders.
2. There are a couple of sandy or leafy loose corners on Goldenrod and Redtail, otherwise the course is mostly smooth and fast.
3. The descent on Honker Bay and the final descent on Redtail are both steep and end in sharp turns at the bottom. Please control your speed during these descents.
4. As of this past weekend, the creek near Cameron Loop was full of water and needed to be crossed using the pedestrian bridge.

Thanks to our generous sponsors again this year, we will have great prizes on offer for top finishers and raffle winners. In addition, every registered rider will receive a discount code for 40% off non-sale items at CAPO and 20% off items at Sports Basement for current Sports Basement members and 11% off for non-members.

Looking forward to seeing you all on October 10th!

The 2026 East Bay Dirt Classic is locked and loaded for Saturday, October 10th!

The course remains the same from last year and can be found here. It is a hair under 21 miles and a hair over 3,000 feet of climbing on mostly rolling fire roads with some single track.

In prior years, most participants have ridden the course on a hardtail or light full suspension mountain bike or a gravel bike.

Registration will be entirely online this year and is capped at 130 competitors. We have sold out the last few years, so please register early. There will be three waves of riders, with the first wave for the fastest cyclists going off at 9:00 am and each successive wave going off in 15 minute intervals.

All registered riders are invited to attend the post-event barbecue and pool party. There will be incredible prizes from our generous sponsors given out to our top competitors and our KOM and QOM winners (segment to be released in a later post). As always, the top male and female finishers will receive custom East Bay Dirt Classic belt buckles. There will be additional prizes awarded through a raffle which helps raise additional money for the Alameda County Community Food Bank.

Ultimately, this event is about raising desperately needed funds and awareness about our friends at the Alameda County Community Food Bank and the Alameda County residents who rely on their services. In total this event has helped to raise over half a million dollars for the ACCFB in the last several years.

More updates to follow.

Looking forward to seeing you all on October 10th!

Cancel your trips, get your bike tuned, make space for all the gnar you’re going to shred, and tell your buddies to do the same – October 10, 2026 will be the next East Bay Dirt Classic!

The 2025 East Bay Dirt Classic is in the books! Thanks to all participants who made this year the best edition yet!

Between the record number of participants, beautiful weather and setting a new record of over $82,000 raised for the Alameda County Community Food Bank, it was our best edition yet. Thanks to all who raced and helped fundraise, we are able to help provide more than 164,000 meals for those Alameda County members who face food insecurity daily.

In the men’s division, 2024 winner, James Kinney, and 2024 runner-up, Sandy Floren, battled it out through the first 2/3rds of the course with Sandy eventually pulling away on Redtail. Sandy ultimately finished first with James in second and young gun, Nils Hummel, taking third

In the women’s division, Sophia Tripcevich returned to reclaim her title from 2024, followed by Sadie Weiner in second and Elle Floren in 3rd. Sophia also once again took home the prizes for top female junior AND QOM!

Finally, please save the date for the 2026 edition of the East Bay Dirt Classic: Saturday, October 10th, 2026. 

Thank you again,

Your friends at C510

One week to go! We rode the course this morning and it’s in perfect shape. The recent rains and some of the grading work EBRP has done have made for fast, tacky trails. There are very few loose areas (beginning of Goldenrod there are some leaves in the corners; descent of Redtail there are leaves and some loose dirt at the very end).

The weather looks to be perfect for the ride next Saturday with cool temps at the start, warming as the sun breaks through the clouds later in the morning.

Here is this year’s course: 2025 East Bay Dirt Classic Course. The only change from last year is a minor change on Goldenrod and we will have a course marshall at that point directing cyclists to avoid confusion.

Reminder: The course start is at 5656 Weaver Place in Oakland. Parking is along Skyline, NOT on Weaver Place. The first wave will roll out with a neutral start at 9 am. Each successive wave will roll out in 15-20 minute intervals following the first wave.

Bring a bathing suit and appetite for the pool party and barbecue following the event. Awards for top competitors and raffle prizes will be handed out at the after party.

Thank you for joining us for the 2025 EBDC and helping support our friends at the Alameda County Community Food Bank! See you next Saturday!

Just under 3 weeks to go! As of Sunday, September 21st, we have 80 registered riders, so make sure you register soon! We have some incredible prizes for the top performers as well as winners of raffle tickets purchased ahead of time or at the barbecue. Pizzaiolo just donated a $150 gift certificate to the event! We also have tons of incredible products from Peak Design, beer from Ghost Town Brewing and East Brother Beer, gift certificates and a commuter bike (!) being donated by Mike’s Bikes, and cycling kits from Pearl Izumi, just to name some of the prizes.

We will be doing a final pre-event ride the weekend of October 4th and posting up-to-date course conditions and an updated course map after that.

Looking forward to seeing you all on October 11th!

Leave this field empty if you're human:

The 2024 East Bay Dirt Classic is in the books, and we at C510 have agreed it was the best year yet. We’re incredibly thankful it was not this past weekend in 98 degree weather. But mostly we’re grateful to all of you for joining us in this annual event to support our friends at the Alameda County Community Food Bank. Through registrations, donations and raffle tickets we raised over $70,000 this year!

Huge congratulations to our top competitors for 2024!:

Our top female finishers:

1. Alex Tripcevich
2. Noelle Davis
3. Katrina Rapa

Alex, a Berkeley High student, was not only our top female finisher but also our QOM holder and Best Young Rider! Since our sponsors are heavy on the beer and wine, we had to make some last minute changes since she took home more than one top prize…She’s clearly going to have a couple more years of strong showings here at the East Bay Dirt Classic.

Our top male finishers:

1. James Kinney
2. Sandy Floren
3. Jason Tang

Fresh of his recent Tunnel Road KOM setting ride, James also set the KOM for our 2024 EBDC segment. His win was due after a couple of 2nd place finishes i the past. Our best young male rider award this year went to 16 year-old Oliver Jacobs. Oliver told us he DNF’d last year. Then he came out this year to notch 6th in a very fast field. Definitely more to come from Oliver next year.

Please check out photos from the event here and here! Many thanks to C510 members Josh Posamentier, Ben Duchac and Peter Lockett for chronicling the event!

We’ll be back on again next year with our hope to return to mid-October. Watch out for our “Save the Date” in the coming months.
