MGXC 2023

Racing is back at Peaceful Valley! To continue the effort in making Mad Gravel a full cycling weekend of playing in the dirt, Rattler Racing is excited to introduce MGXC, a mountain bike race in and around the Peaceful Valley Scout Ranch in Elbert, Colorado. The course this year will be a 5 mile circuit with multiple laps. The start/finish area will be set right under the huge dining hall where the crowd will be cheering you on. MGXC will be the third day of racing over the Mad Gravel weekend.

** This will take you to the Mad Gravel page. You can sort there for MGXC racers**

What to Expect

Set right in the heart of Peaceful Valley Ranch, this sweet 5 mile lap winds through the varying terrain in the eastern tundra of Colorado’s front range.  The course is a mix of technical sections, fast and furious single track and double track roads. You will still be tested with about 800 feet vertical per lap. The start/finish will be based right in front of the indoor/outdoor dining hall overlooking the giant open range of Elbert County.

Pricing: Adults – $70, Juniors (13-18) – $55, Juniors (9-12) – $28, Juniors 8 and under FREE. If you have a junior (8 and under) that wants to race on the bigger course with 9/10 year olds, they can move up and will need to register with 9 year old pricing.

Course 411: The course will be marked at all critical intersections the day before the race. Pre-riding will not be allowed prior to race day as the Ranch is private. There will be an opportunity to ride the course all of Memorial Day weekend. If scouting it out during another active race, please maintain a minimum 200 foot following distance if on an active course.

Spectating: You name it. Peaceful Valley Ranch has viewing opportunities all around the property. But we can’t oversell the venue headquarters enough. It will be the place to be.

Number Plates: This is a lap timed event. All racers will have a number plate with chip except for the Elite Mini Kids Race.

Results: Posted at the conclusion of your race and online the following day.

MGXC is a USAC sanctioned event. Registrants can purchase an annual or one-day license.



Cancellation Policy

Mad Gravel and associated events does not offer refunds. We completely understand that unfortunate circumstances happen, but we plan this event way in advance from a cost and resource allocation perspective, and the financial and administrative burden is high. On the plus side, Mad Gravel does offer transfers and deferrals. If you would like to transfer your entry to another rider, no problem. Just drop us a line and we can get it taken care of for you at no charge. The same goes for deferrals. We realize schedules change, life events happen, and injuries can surprise us. We will happily defer your entry fee to next year. Again, no charge, but you must let us know prior to race day.

Race Rules

  • Rule 1: You will smile no matter the pain.
  • Rule 2: Yes, you must wear a helmet and have adequate eye protection.
  • Rule 3: Be nice to the land, it never did anything to you.
    3B: Stick to the trail. Course cutting could be as simple as creating a new line on a switchback. Please don’t do it.
  • Rule 4: No headphones. Sing to yourself.
  • Rule 5: If you don’t thank a volunteer, you will be publicly shamed.
  • Rule 6: This is mountain biking. Please, please, please be considerate of other racers whether you are in front being a superhero, or in back preparing to vomit. We all know this, but the occasional reminder never hurts.

Number of laps will be dependent on category and/or age group.  Awards ceremony will follow each race. Remember, your age will be calculated as RACE AGE, which is the age you will be on 12/31/2023.
