THIS EVENT IS OUR HIGH SCHOOL MOUNTAIN BIKE TEAM FUNDRAISER

What and why is The Diamond Grinder?

The Humboldt Diamond Grinder was originally developed as a gravel-only ride by Revolution Bicycles in cooperation with Green Diamond Resource Company (GDRC); the Diamond in Diamond Grinder! Now in cooperation with GDRC and the City of Blue Lake, the Humboldt Diamond Grinder has evolved into a multi-course ride with epic routes. It is now a fundraising event for the Humboldt Composite High School Mountain Bike Team (HCMTB) and Redwood Coast Mountain Bike Association (RCMBA), two volunteer-only local nonprofits working to improve the local cycling experience. Check out the links below for more information on these awesome groups!

Race Day

We are planning early starts for the longer routes. Showers Pass and Lone Star will start at 7 am. The shorter Diamond Grinder route will start at 10 am. The race start is a one mile easy spin up Hatchery Road. All of the courses will climb up through the scenic redwoods and empty gravel roads of Green Diamond Resource Company’s timberland. The long courses will lead you out of the Mad River watershed onto lightly traveled public roads through mixed forests, open fields, and oak prairies. The Showers Pass route is hands down the most epic gravel loop in Humboldt County! If the Showers Pass or Lone Star routes seem too much then the traditional Diamond Grinder course is for you. This route stays inside the watershed and doesn’t leave private property. This means almost zero pavement and zero traffic! The end of this route has a bonus stream crossing allowing you to freshen up before heading back to camp!

Post Race

After the race you have a short downhill spin back to the venue. Now it is time to kick back and enjoy food and libations. We will have burritos with SHERA SAUCE at the venue. Get the lawn chair out and enjoy the perfect weather. The average high in July is 82F and the average low is 57F.

Awards

We will have medals for the top three finishers in all categories.

Should The Family Come?

While you are riding there are lots of options for the family. If you are a biking family there are RCMBA’s epic enduro trails and hopefully Blue Lake’s pump track will be up and running! The Mad River is walking distance from the camping area and offers beaches and swimming. We also have great ocean beach walks and nature hikes nearby; Trinidad Head, Sue-meg State Park, and Prairie Creek State Park are a short drive from the venue.

Redwood Coast Mountain Bike Association
