    Racer Timetable 

     What time should I plan on arriving at the Golden Gate Canyon State Park Visitor Center so I can be directed to either the Start/Finish or the shuttle parking lot?

    6:00 a.m. Race Start – There is NO shuttle for the 6 to 6:20 a.m. race start.  If you have a parking pass which was obtained in mid May, arrive between 4:50 – 5:20 a.m. .  You should plan on arriving no later than 5:20 a.m. and no earlier than 4:50 a.m.

    7:00 a.m. Race Start – Please see the shuttle schedule above and plan accordingly, based on where you are driving from. All 7:00 a.m. race starters must be ready to board the shuttle buses at ???a.m.

    8:00 a.m. Race Start – Please see the shuttle schedule above and plan accordingly, based on where you are driving from. All 8:00 a.m. race starters must be ready to board the shuttle buses at ??? a.m.

    Shuttles buses will begin return trip to the shuttle parking lot at approximately 3:30 p.m. and will depart when the bus is full.
    No pets or strollers on the bus.

    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.



    Only parking pass holders may park at the Start/Finish. Parking passes are issued to to those who are 6 – 6:20 a.m. starters who have at least FOUR 6 a.m. starters in their cars. These passes are assigned to entrants who request a pass and who meet these requirements. All others must take the shuttle bus from the Jefferson County Human Services Parking Lot in Golden or get dropped off. The shuttle buses are meant for the 7 and 8 a.m. starters. They will not arrive in time for the 6 a .m. starters.

    Parking pass holders minimum of FOUR(4)), 6 a.m. starters or folks from the west 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 identified as either “Carpool”, “Runner Dropoff”, or Volunteers. 50K racers must arrive no earlier than 4:45 a.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 shuttle bus parking lot. The buses will leave the parking lot one right after the other starting at 5:00 a.m.  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 time to pick up packets, eliminate your coffee, get your Aid 3 and finish line drop bags dropped off.

    No dogs or strollers on the shuttle buses.

    No Crews, families, or Spectators are allowed for the 2022 Race

    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 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. No parking on Crawford Gulch Rd as racers have done in past years.  Please tell your family and friends to plan on taking the shuttle bus to the Start / Finish.
      2. NO SPECTATORS. Golden Gate Canyon State Park has seen a 60% increase in park visitors. They can no longer accommodate spectators for this race. The unique thing about this race is all the Happy Hour events that lead up to this race allow everyone to connect. You will be surrounded by new friends and receive lots of support throughout this entire race. 
      3. DO NOT LITTER. This applies anywhere on the course, including at aid stations. Please respect the park and other visitors.
      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.
      5. CARRY YOUR OWN HYDRATION SYSTEM. We do not provide cups at aid stations, therefore we ask that all racers carry at least a water bottle to fill up at aid stations. 50K racers are advised to carry at least 40 oz of fluid. The back of the packers will take up to 3 hours to get from Aid 3 to Aid 4, so plan accordingly. You should have at least 60 oz of water for 3 hours.
      6. CHECK-IN AT AID STATIONS. All racers must personally check-in at each aid station. Should you decide to drop from the race, you must have the ham operator cut your wrist band off. Runners are liable for any search and rescue expenses!
      7. ADHERE TO CUT-OFF TIMES. 50K runners must arrive at Aid 2 by 11:00 a.m., Aid 3 by 12:30 p.m. the junction of Lion and Burro trails (mile 25.5) by 3:15 p.m. to begin the Windy Peak loop, and Aid 5 by 4:45 p.m. If you do not make these cut-off times you will not be permitted to continue with the race. No exceptions! The Finish line closes at 5:30 p.m.; any racer crossing the finish line after 5:30 p.m. will not be considered an official finisher. Please respect the volunteers who are working this race and honor these cut-off times. If you do not follow this rule, you will be banned from running any future Dirty 30 race.
      8. INSURANCE NOT PROVIDED. The race will not cover any incurred emergency, medical, or rescue costs. Racers are advised to have personal insurance should you become injured.
      9. NO DOGS. Dogs are not permitted on the course, on the buses, at the Start / Finish line, or the post-race festivities. The race cannot cover incidences with your pets. You will be asked to take your dog away from this event, so please leave your four-legged friends at home.
      10. NO PACERS. Pacers are not permitted.
      11. HIKING POLES. Although most racers do not use them, feel free to use hiking poles if you want, especially up Windy Peak.
      12. BRING YOUR OWN PLATE AND FORK. Please help us make this event green by bringing your own plates and forks. Put them in your Finish line drop bag. Crew and spectators should also bring their own plates and forks. We would like to avoid putting 1,000 plates and forks in a landfill.
      13. MUST BE PRESENT TO WIN.  Pack a change of clothes in your Finish line drop bag and plan on staying for the Awards Ceremony, which will start around 5:00 p.m. You must be present to win! More than that, stay for the fun and to be with your fellow runners, friends, and family!

    Print out this race day plan diagram and fill it out to help you stay on top of your fueling and hydrating needs to have a successful race.

    We all look forward to a return to events, and hopefully, we will see improvements to our current situation by next summer and see you at Dirty 30 events again! To be on the safe side, we are putting the following safeguards in place now. These ensure we have in place what may still be necessary at the time or simply a layer of thoughtful, proactive care of our participants, spectators, and volunteers.

    We look forward to better days and celebrating outside and on some of the best trails out there.

      Measures we will carry out as needed include but are not limited to, the following:
    • • No spectators, families, friends or crews for the 2022 race.
    • • Set up socially distanced packet-pick up, such as a drive-through or other system that keep people safe.
    • • Limit the number of racers to 45 on each bus
    • • Organize limited-touch aid stations to supply what you need quickly and safely.
    • • Stagger the start, using waves of runners every 5 minutes, starting with the fastest runners first.
    • • Once you do finish, maintain proper social distance as you get your meal

    After two years of navigating this pandemic, participating in races, and volunteering at a race that went off successfully, I am confident that we can put on safe, fun races.

    While you are training, we will hold our usual “Happy Hour” events as online virtual events until we can hold live events again. We have a fun schedule starting with David and Megan Roche, and hopefully followed by Courtney Dauwalter, and Maggie Gutterl. We are also planning on hosting the Dirty 30 “Sistah’s Extravaganza” in April.

    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 for the 2022 Race, family or friends will not be allowed to park at the start/finish area including anywhere along Crawford Gulch Rd. or at any of the aid stations.&nbsp Please understand that any deviations from this rule will jeopardize the permits for this event.

    How much time should I allow for the shuttle ride to the Start / Finish?

    Allow ?? minutes. All 7:00 a.m. racers must arrive at the shuttle parking lot by ?? a.m. 8:00 a.m. startes must be at the shuttle parking lot by ?? 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. No dogs 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?

    NO 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. No spectators, family, or crews for the 2022 race.

    How do I find someone to carpool with?

    You can find someone to carpool with using Ricky Rides or Dirty 30 Running Private Facebook Group. We encourage everyone to go to these platforms 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.

    Thanks to all of our incredible sponsors
