Dirty 30 Race Details

To both spread out the start line and give all participants the time they need to complete this race, the 50K has three start times or waves. See below.

  • Simply choose the best time for you based on your anticipated finish time *Please keep in mind that the length, challenges, and terrain of this race, like any trail race, contribute to overall slower times than you might be used to.
  • Please look at finishing times from last year’s race and at age-category times.
    Previous Year’s Results
  • If you are new to ultra running, pick your start time based on your relative overall finish in other running races you have done. If you have not run any races, perhaps get out and run with some other folks who have and compare your pace with them, again keeping in mind that this is a trail run and times are slower.
Important: The 6:00 a.m. start is reserved for those at the the back of the pack. If you are running faster than 16 minutes per mile average, then you need to start at 7:00 a.m. If you are not a back-of-the-packer, please do NOT start at 6:00 a.m. 6:00 a.m. – Back 1/3 of the pack – 8:30 to 11:30 hour finishers 7:00 a.m. – Middle 1/3 of the pack – 7:00 to 8:30 hour finishers 8:00 a.m. – Front 1/3 of the pack – 4:30 to 7:00 hour finishers

Shuttles run regularly all day for racers, crews, and spectators.
No pets or strollers on the bus.


My family and or friends want to come watch me on the course and see me finish. Can they drive to the start/finish area?
No spectators, family or friends will be allowed to park at the start/finish area including anywhere along Crawford Gulch Rd.  All spectators will be directed to the shuttle parking lot to catch the shuttle bus. Please understand that any deviations from this rule will jeopardize the permits for this event.  Please plan ahead and allow time to take the bus.  There will be an additional shuttle bus going to  Aid 2 and 3 as well.  Please see the shuttle schedule and plan accordingly.

How much time should I allow for the shuttle ride to the Start / Finish?
Allow 25 minutes. All racers must arrive at the shuttle parking lot by 5:30 a.m. Each bus needs to be filled or there will be runners that will not make it to the start on time. If you miss a bus you will miss your start. Please plan to be early. Spectators may board after all runners are boarded. No dogs or no strollers on the bus. Dogs are not permitted at this event.

Can I or my family park on Crawford Gulch Rd just south of the start/finish area and walk to the start/finish?
NONo Dirty 30 participants or spectators will not be allowed to park on Crawford Gulch Rd. Park rangers do not want anyone walking along the road, because it is narrow with no shoulder and then have deemed it unsafe. You will be directed by parking officials at the Visitor Center on Hwy 46 and Crawford Gulch Rd. to the shuttle parking area.  Please follow this rule. Any deviations from this rule will jeopardize the permits for this event.

Can my family and friends drive to Aid 2 and 3 to crew me, or cheer me on?
No. Shuttle buses will take your crews to the aid stations. The Aid Station Shuttle Bus will run from the Start / Finish area to the Aid stations. There are not enough parking spaces at these aid stations so please do not try to drive to the aid stations.

How do I find someone to carpool with?
You can find someone to carpool with using Ricky Rides. We encourage everyone to go to this one spot to find a carpool. Reach out, make new friends. This has worked really well in the past. You can easily meet your carpool at the Hwy 93 and Hwy 46 junction.  There is a small parking lot on Hwy 46 just west of Hwy 93. You can also park in the Mountain Smith parking lot in the business park just north of Hwy 46 on Hwy 93.

Can I Camp at the Red Barn or Start/ Finish?
No. There is no camping at the Red Barn or the Start/Finish. There are suggestions for where to camp on the Where to Stay page.

We have partnered with RickyRides to help you arrange a carpool. Here’s how it works:

  • RickyRides is a bit like a forum. A runner creates a “ride post” which is displayed on the map. The map will show a van if they are offering a ride from their location, or a man if they need a ride.



The first 75 cars with a minimum of THREE(3), 50K racers will be directed by parking marshals, at the Visitor Center, to park at the start/finish/Nott Creek TH. It might be helpful to look at a map to understand this. The Visitor Center is the junction where cars are either directed to park at the start or at the shuttle parking lot. 50K racers must arrive no earlier than 4:45a.m. and no later than 5:20a.m. at the Visitor Center where a marshal will be directing traffic. Allow 25 min to get to the visitor center from the junction of Hwy 93 and Golden Gate Canyon Rd, Hwy 46.
The remainder of the 50K cars will be parked at the Gilpin County Fairgrounds parking lot which is just 4 miles west of the visitor center. Turn left on Norton Drive, the parking lot is on your right. The 4 buses will leave the parking lot one right after the other starting at 5:45am.  Everyone, please plan to be ready to load on the first shuttle bus.  It is imperative that each bus is completely filled with runners in order for every runner to get to the start in time.  This will give runners 45 – 30 min. to pick up packets, eliminate your coffee, get your aid 3 and finish line drop bags dropped off. Please plan to pick up your packets at packet pick up at Runners High in Golden to help make race morning run more smoothly.

ALL SPECTATORS will park at Gilpin County Fairgrounds as well and take a shuttle bus to the start. Please see the shuttle schedule for times.  Spectators will be shuttled to aid 2 and 3.  Spectators will not be allowed to park at these aid stations.

No dogs or strollers on the shuttle buses.

It is very important that spectators wait to make sure all racers are on the bus first.  If there is room after all runners have boarded the bus, spectators may ride.  If there is no room, the buses will be back to pick up the spectators.

Friends and Family are encouraged to support at the race for the 50K & 12M on Saturday, but know:

All friends, family, and spectators will be directed to the shuttle parking lot.  Absolutely no spectators will be allowed to park at Aid 2, 3 or the start finish area.  Shuttle buses will take spectators to aid 2 and 3 and then back to the finish line.  This shuttle bus business is not an exact science, so PLEASE plan ahead and be prepared to wait for buses and at the aid stations to see your runners.

  • No Dogs or strollers on the buses, please. Dogs are not allowed at the Red Barn or Start / Finish.
  • Spectators may hike to the aid stations and on the course, but be mindful of the runners.

All runners are asked to abide by these simple rules so we can continue to organize this great event in the years to come! Breaking any of these rules may result in disqualification, subject to the race director’s discretion:

    1. FOLLOW THE PARKING AND SHUTTLE RULES. The park officials are watching closely this year for everyone to be cooperative and follow the rules.

    4. STAY ON THE TRAIL. Do not cut switchbacks. Do not stray from the trail when it funnels down to a single-track. Course cutting causes erosion and violates park policies.
