2021 East Bay Dirt Classic Course Set!

The 2021 East Bay Dirt Classic course was released this weekend! The 2021 course climbs 4,000′ over 25 miles on nearly all dirt. This is a mostly non-technical course with majority fire roads and some single track. The format will be the same as last year with a participant’s total time being the sum of 5 defined segments. The segments this year can be found on the EBDC registration page. Once again 4 of the 5 segments are primarily climbing segments with one segment being a sweeet rolling single track segment (Sensei’s Surge). Please remember that there are no trail closures for this event and all participants need to yield to other trail users and obey all trail etiquette. To be included on the 2021 East Bay Dirt Classic Leaderboard, a participant needs to register and ride the entire course and complete all 5 segments in order in the same single ride.

The rolling two week window to ride the course and find yourself on the leaderboard opens Saturday October 2nd and closes at 1 pm sharp on Saturday October 16th. Participants can ride the course as many times as they choose during the 2 week open window. Included in this year’s registration will be a limited edition 2021 East Bay Dirt Classic T-Shirt and a post-ride barbeque and pool party on October 16th with presentation of prizes to top finishers. Sponsors of prizes for this year’s event include Specialized, Mikes Bikes, Sports Basement, Capo Cycling Apparel, Jakroo Cycling Apparel, East Brother Beer Company and Almanac Beer Company. All vaccinated competitors are invited to join the barbeque on October 16th regardless of when they ride the course.

As in each prior year, all proceeds from the registration fees and associated fundraising go to our friends at the Alameda County Community Food Bank (ACCFB). The ACCFB is a remarkable local organization that provides food and health education to 1 out of every 5 residents here in Alameda County each year. The need in Alameda County has only increased during the course of the current pandemic. On the registration page, you will see an option to donate in addition to the registration fee. Anyone who donates in addition to their registration fee will be entered into a raffle for prizes from our sponsors to be handed out at the barbeque on October 16th. Participants must be present to win. Anyone who wants to join the C510 team in our fundraising efforts for the ACCFB this year, please email us or visit our GoFundMe page.

Thanks to all of you who contribute to the success of this event and the support of our Alameda County neighbors.

Be safe out there and above all, have fun!

And…we’re back!

The last few months have offered promise and hope with California re-opening and opportunities to recreate with friends increasing. We hope you all have weathered the last 18 months and you and your friends and family are healthy and well.

We are excited to announce the East Bay Dirt Classic is back for 2021! This year we will return to some of the original elements while retaining some of the changes from last year. To that end, we will host this year’s edition of the East Bay Dirt Classic on Saturday October 16th, 2021 with a BBQ, pool party and presentation of awards to follow for all participants. We will also offer an open 2-week window for those who want to compete but are unable to participate on the day of the event. This open window will start on October 2nd and close at the end of the event mid-day on October 16th. We have also decided to retain the “enduro” format from last year’s event, with 4-5 timed segments throughout the course. A participant’s composite time from all segments will determine their overall ranking. Participants must ride the entire course, but will only be timed on these segments.

We are currently designing the course for this year’s edition, but expect it to be between 25-30 miles of non-technical dirt with some road intermixed with roughly 4-5,000 feet of climbing. The course will be revealed at least one month prior to the start of the event, with GPX, TCX and Strava files available for review and download prior to the event.

Finally, as in prior years, all proceeds and associated fundraising from this event will go to our friends at the Alameda County Community Food Bank, who need our support this year more than ever, with nearly 1 in 4 Alameda County residents facing food insecurity. To participate in the 2021 edition of the EBDC we ask that you donate $75 to our fundraising efforts. More information on this to follow as we get closer to the date.

We hope to see all of you on October 16th, and for those who cannot make it on the day, we look forward to watching the competition unfold in the 2 weeks leading up to the event!

And that’s a wrap! The 2020 edition of the East Bay Dirt Classic has come to a close. Not with a whimper, but with a bang.

There were some incredible rides out there this weekend and some shaking up of the leaderboard on the QOM side. While Kristen V maintained her relatively safe lead atop the women’s leaderboard, Meredith Stowe Christie came out on Sunday and threw down to notch into 3rd only to have another young gun, Ariana Milelli, come back and shave minutes off her first time to notch into second at 1 hour 2 minutes 4 seconds, pushing Gabriella Sterne into 3rd.

On the KOM side, things remained relatively static, though Dan English came back out and gave it another go, turning in another scorching time of 48 min 25 seconds. An incredible effort yet again, but Fun Ghi’s lead was a bridge too far. Rounding out the top 3 is Jason Tang. Only 17 seconds came between Dan and Jason after 5 tough segments. Prizes will be given out to the top three in both the KOM and QOM categories. We will reach out to you each individually. One of the downsides of having so many fast youngins out there (aside from being reminded of the vigor of youth) is we have nowhere to send all of the incredible beer provided by our generous sponsors…

The start of the course on Goldenrod

It was a novel approach this year, born of necessity during unconventional times. We have had the opportunity to speak to some who raced this year and so far the comments have all been positive. One universal comment, however, has been the disappointment at missing the post-race barbeque. Rest assured we have every intention of reviving the after-party next year if conditions permit.

Please feel free to reach out with comments about the event, the format or if you registered, donated and rode, but don’t see your name on the leaderboard. Everyone who registered and donated can pick up their limited edition 2020 East Bay Dirt Classic buff at Sports Basement in Berkeley this Sunday October 25th. As a registered participant this year you will also receive an in-store discount on any gear you purchase while there.

Finally, with all of your help and the generous support of many others who donated to our fundraiser this year, we raised over $30,000 to support the Alameda County Community Food Bank. This year in particular these funds will help provide critical support to those residents of Alameda county facing food insecurity.

We loved seeing the spirit of friendly competition as we saw some of you riding past on your way to completing the course. And we enjoyed following the battles atop the leaderboard as the days of the open window elapsed. So thank you. All of you.

Until next year, stay healthy and safe and keep the rubber side down.
