The Human Potential Running Series Presents:

The Silverheels Trail Runs @ COMO ROUNDHOUSE

The Silverheels Trail Runs take place at an average elevation of over 10,000’, in one of the most visually stunning areas of Colorado. The course features a mixture of single track trails and fire roads, with a few stretches of dirt road; it takes runners through high alpine and sub-alpine meadows loaded with wild flowers, with expansive views of the South Park Valley and beneath the towering "Decalibron" 14er's. You'll run through ghost towns, past abandoned mines, awe at the wildflowers in full bloom, and dance under the watchful eye of Silverheels Mountain herself and the ever stunning Milky Way Galaxy. Our 10-Mile and 18-Mile options are run on the gorgeous Gold Dust Trail traveling through massive aspen groves, over many high mountain creeks, through old mining encampments, and along a miners ditch hand dug by those in the late 1800s.

Start your morning the Alma way — with a little fresh mountain air, some movement, and a big stack of pancakes.

Join us for the Firefighter 5K, a laid-back community run where everyone is welcome. Bring your kids, your dog, your friends — run, jog, walk, or just saunter your way through beautiful Alma. This event is all about getting outside, having fun, and kicking off the day together.

After the run, head over to the NW Fire Protection District Fire Station for a delicious pancake breakfast hosted by IAFF Union Local 5227.

Even better, proceeds from the race entry fees will support the Firefighter Union’s selected charity, so every step you take helps support a great cause.

Come for the run.

Stay for the pancakes.

Celebrate community in the highest incorporated town in North America.

Welcome to the Staunton Rocks! Marathon & Half, an event put on by trail runners for trail runners.

Touring the renowned singletrack of Staunton State Park in Colorado’s Front Range Mountains southwest of Denver, the race will take you back in time as you glide by historic buildings and old milling operations. The flowing trails and gradual climbs & descents will allow you to open up your running stride, while technical features scattered throughout will give your feet occasion to dance. Take in 60+ mile views from the numerous overlooks on course, run by scenic lakes and streams, and catch a glimpse of the numerous raptors that inhabit the stunning rock formations throughout the park. With runnable trails and generous cut-offs, our aim is to offer a trail running experience that is challenging, yet accessible to all.

We aspire to not only offer a first class trail racing experience on a challenging, scenic and impeccably marked course, but also a top-notch post-race experience that will leave your bellies full and the stories flowing.

***There will be GF/Vegan alternatives for nearly all non-GF/V standard offerings. These are typically held back to save them for those who need them, so please ASK! Also note that while we will do our best to keep utensils and trays separated for these as well as common allergens, this is the backcountry and cross-contamination can occur.

While we will provide plenty of electrolyte options in drink mix and salty real foods, we deem the risks associated with salt in concentrated pill form to be more than we're comfortable providing. We won't restrict runners from using their own salt caps, but will not have them available at aid stations.

Course Marking

The course will be well marked with pink flagging and pink pin flags. Important intersections will be supplemented with flour ground markings and directional arrows. On longer stretches of trail without intersections, confidence flagging will be placed approximately every quarter mile. Turns will be marked heavily.

Toilets

Park restrooms are available at the Ranch Hand Start/Finish, Mason Creek Trailhead, and on the Bugling Elk Loop approaching the Elk Pond Aid Station.

If you do need to relieve yourself outside of these spots, please practice appropriate Leave No Trace principles. Aid stations will have toilet paper available.

Crew Access

Family and friends can meet their runners at the Ranch Hand Start/Finish and Mason Creek Trailheads. Crew or family vehicles will need to pay the regular $10 park entrance fee. Carpooling is highly recommended to save on park fees and limit traffic and parking congestion at the trailheads. Use the Mountain View Park 'N Ride on Highway 285 just 5 miles east of the park for carpooling.

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.

Parking at Staunton will be available beginning at 6:00am. Passes for carpooled runners are covered as part of your race entry fee, and you'll receive your pass from our parking crew when you arrive at the park race morning.

Race traffic will be directed first to the Meadow Overflow lot, followed by the Meadow lot. Both lots are roughly a half mile walk from the start/finish. Please follow directions from the parking marshals and plan sufficient time to arrive and park.

All vehicles with a single registered runner will be directed to park at the Mountain View Park N Ride, 5 miles from the park, and take one of our race-provided shuttles, which will start running by 6:00a. Please arrive at the park & ride at least an hour before your start time if you plan to take the shuttles.

Runner drop-off is allowed at the park entrance. Turn in to the main park road off of Elk Creek Road, and proceed to the first parking marshal. Tell them you are just dropping off a runner, and they will direct you to turn left, disembark your runner, and circle back out of the park. Runners getting dropped off will have approximately a half mile walk from the drop off to the start.

Runners are welcome & encouraged to make a new friend in the PnR lot on race morning to drive in together. You can also post rideshare offers/requests on our Facebook Event.

Runners are welcome to leave a bag at the start/finish for post-race access (especially those runners taking the shuttle). Please label your bag with your name and bib number (we'll have duct tape & sharpies at packet pickup if you forget).

Any crews or spectators will be required to have a Colorado State Parks Annual Pass or purchase a park entry pass on-site for $10.

Please be mindful of additional park traffic that will arrive throughout the day.

The Human Potential Running Series Presents:

The Sawmill Trail Runs @ Staunton State Park

The Sawmill Trail Runs; first started as a “Fat Ass” event at White Ranch Open Space in Golden, CO in December 2013. We incorporated it into an official trail race starting in December 2017. In 2021, this event was moved to its new home at Staunton State Park in Pine, CO featuring 50k, 16-Mile, and 8-Mile distance options.

Staunton State Park is a gem within Colorado’s State Park system. From high grassy meadows at 8,100 feet to soaring granite cliffs over 10,000 feet, Staunton State Park’s varied geology, soils, water features, and climate support rare and unexpected plant communities and a rich diversity of wildlife and provide a myriad of outdoor recreation opportunities. The park is located approximately 40 miles southwest of downtown Denver, north of US Highway 285 and about six miles west of Conifer in Pine, CO.

Special Event Notes: Traction devices such as micro-spikes are welcome should conditions permit. Snowshoes will also be permitted in the event of snow depths exceeding 6″. No other flotation devices will be approved. In the event of deep snow and treacherous conditions on the 50k’s first loop, the loop will be closed and we’ll ask 50k runners to endure the 16-Mile course, twice consecutively.
