Grand Gear Grind (G3)

The Grand Gear Grind (G3) is a mountain bike stage race covering the best single-track that Grand County Colorado has to offer. Expect 90 miles of pristine and challenging trails in Winter Park and Granby. You will be tested, you will be tired, you will be wondering why you signed up, you will cry, but mostly you will smile.

We are proud to be working with the US Forest Service, Rendezvous, Granby Ranch and many others to bring you this race. They are playing a huge role in making this event happen and we thank them for being involved!

  • Rule 8: If you don’t thank a volunteer, you will be publicly shamed.
  • Rule 9: This is mountain biking. Please, please, please be considerate of other racers whether you are in front being a superhero, or in back getting ready to vomit. We all know this, but the occasional reminder never hurts.

While we would like to open this up to everyone, it's still a stage race with an overall result. However, the option is there to form a team over the 3 stages. Teams can be made up of 2 or 3 people and racers can then participate in individual days.

Yes. Each stage completed counts as one day toward qualification. You do NOT have to finish the entire stage race. You must have an annual USAC license to race. You can purchase at the race but way easier to do it in advance.

For purposes of qualifying for USAC, yes, every stage completed does count toward one day of qualification. You can race subsequent days of the race but your result will not be calculated into the overall result.
