Aid Stations

We hope for close-to-normal conditions on race day, as related to the COVID-19 pandemic. Current race information reflects a normal year.  Details may change as race day approaches, and any changes will be communicated to registered runners well in advance.  For reference, here are the 2020 COVID Safety Protocols.

* Drop bag location

With the exception of the fluids-only aid at Arthur’s East (mile 47.8), all aid stations will be fully stocked and staffed with volunteers.

On hot days we may have an additional water drop on the access road behind Arthur’s Rock at about mile 21 on the first loop and mile 29 on the second loop. Please plan on carrying enough water from Arthur’s or from the Finish area to get up and over the 7.4 mile leg. This water is primarily intended to help 50 milers who may get caught short on water on the slower trip back up and over to the Arthur’s aid station. We will communicate yes/no on this water drop on race week.

All full service aid stations will stock the following items:

  • VFuel bulk gel and sports drink. (Please bring your own gel flask for refills.)
  • Water and Ice (Ice may be limited at the Towers aid station)

The following items may be subject to change depending on the weather forecast and what we may find in season on race week. But you can count on a general selection of the following items:

  • Salty snacks: Pretzels, potato chips, corn chips
  • Fruit: Oranges and Bananas plus additional variety depending on what might be available
  • Sweets: Cookies, M&M’s, Gummy bears
  • Soda: Coke, Ginger Ale

*Aid stations will not provide water cups. All runners are required to carry their own water bottle or hydration pack.

Vfuel gel will be provided in bulk containers so please bring your own flask to fill at aid stations.

We will have a limited supply of small cups for soda and other drinks. But to help us cut down on waste, please carry an extra small bottle or flask if you can.

Drop Bags

If you have any specific personal needs, drop bags will be allowed at the Horsetooth Trailhead (Mile 10.3 and 39.5) and the Soldier Canyon finish (Mile 24.9 for the 50 milers).

Horsetooth Drop Bags must be dropped off at the start by 5am on race morning. We will not have a second transport shuttle for the later 25M start. 25M runners may also hand off their Horsetooth Drop bag at packet pickup.

Soldier Canyon (Finish) Drop bags may be dropped off any time before the start of each race.

Please keep your drop bag to a reasonable size (small duffel bag or stuff sack).

Drop bags should be clearly labeled with your name and bib number and should be securely packed to be outside in any weather for the duration of the race. No glass, hard containers or coolers, or paper bags/boxes. Please do not leave any valuable items in your drop bags – volunteers are not responsible for lost items.

Drop bags will not be returned to the start until the Horsetooth aid station shuts down and packs up at the end of the day (after 5p). If you finish early and need your drop bag before heading home, you are welcome to drive around to the Horsetooth trailhead (about 15 minutes) to pick up your drop bag. Items left over after the race will be left in a lost and found box at Altitude Running for two weeks before being donated.

Crew Access

Family and friends can meet their runners at the start/finish at Soldier Canyon, Arthur’s Trailhead, and the Horsetooth Trailhead. Runners will receive one pass into Lory park for the race. Any additional crew or family vehicles will need to pay the regular $9 park entrance fee. A Larimer County Parks pass or $9 day fee (separate from the Lory entrance fee) is required at the Horsetooth Trailhead. Carpooling is highly recommended to save on park fees and limit traffic and parking congestion at the trailheads – especially the Horsetooth trailhead, which is likely to be packed with regular park visitors. All trails are open to the public, so family and friends are allowed to run, hike, or bike on the course; however, pacing or crewing outside designated aid stations is not allowed and will result in the disqualification of your runner.
