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!

Race Date: June 17, 2021

  • Sag vehicles
  • Medical support throughout the course
  • Professional Timing
  • Post Race party and awards
  • Plenty o’ food, drink and beer by provided by our sponsors

Terrain: Classic mix of long punishing climbs, fast and flowy descents, short punchy technical rock gardens and everything you’d expect in a XC endurance race. Winter Park and surrounding areas has it all.

Equipment: All bikes are legal for the race, with the exception of E-bikes. We can’t overstate the importance of your bike running in top condition on the day of the race. Like you, it will be challenged. And, it’s your friend. Help a friend out.

Course 411: The course will be marked at all critical intersections. It is the rider’s responsibility to study the course and have directional backup. Remember, we must adhere to all traffic rules. Always stay to the right of the center, especially on the fast descents. Weather can always be a factor in Colorado. Plan accordingly! We will have a medical team on course in various areas and roaming. As always 911 is your friend. Marshals will have radios as well. Good communication wins the day.

Spectating: There are many ways to view this event. Please consider routes that don’t interfere with riders as you make your way to a spectating spot. A map will be provided as we get closer to race day.

Lodging: For this 3-day event, there are a ton of lodging options in Granby Ranch, Fraser, and Winter Park. All are good areas to grab a VRBO or AirBNB. Plenty of camping in the valley as well as a large selection of hotels.

Number Plates: You will be issued a number plate for the entire race. If you damage it during the race, we will issue a new one. If you lose it, well…don’t.

Results: Posted on a daily basis and each subsequent day will have cumulative scoring.

Timing/Awards: Each day will have podium announcements for the day’s winner. Saturday will have the day’s podium as well as awards for the overall top spots for G3. Your final time is the TOTAL time elapsed over the 3 days of racing.

USAC: 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.

Refund Policy: Full refund will be honored until April 30, minus any registration costs. Starting May 1, no refunds will be processed, but transfers or deferrals will be allowed up to the day of the race.

Other 411: While we would like to open this up to everyone, it is still a stage race with an overall GC result. The 2021 edition of G3 will not have the option for racers to sign up for an individual stage. However, racers do have the option to form a team over the 3 stages. Teams can be made up of 2 or 3 people and racers can then participate on individual days. If a DNF or DNS results in one of the days, other days can still be raced but there will be no overall GC result.

Race Rules

  • Rule 1: You will smile no matter the pain.
  • Rule 2: You must wear a helmet and have adequate eye protection.
  • Rule 3: If you do not complete a stage, it will be a DNF for the entire stage race, but you can still participate in subsequent stages. You must let racer staff know of the situation.
  • Rule 4: This is a self-supported race. You can’t ride with a buddy, unless that buddy is part of your DUO team.
  • Rule 5: No pedal assist bicycles. If you want to ride a unicycle over 90 miles, no problem. Yes, you can change bikes from one day to the next.
  • Rule 6: Be nice to the land, it never did anything to you.
    6B: Stick to the trail. Course cutting could be as simple as creating a new line on a switchback. Please don’t do it.
  • Rule 7: No headphones. Sing to yourself.
  • 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.
  • Rule 10: On all gravel and road sections, do not cross center line. This could result in disqualification. Please follow all the rules of the road. The race course is open to traffic!


We will have an open category and age group categories. Your racing age is how old you will be on December 31, 2021. We will consider running other specific categories like Single Speed and Clydesdale if we get a minimum of 5 racers signed up by race day.
