The Rad Dirt Fest course map and aid stations

Three gravel courses from Main Street in Trinidad, Colorado, from 47 to 113 miles, with the Spanish Peaks on the skyline.

2027 dates not announced yet, usually in September Trinidad, Colorado

The Rad Dirt Fest is Life Time's gravel race in Trinidad, in the far south of Colorado, run since 2021. All three courses leave Main Street on the same Saturday morning: the Stubborn Dolores 110, the Anteloop 70 and the Habanero 40. Each one passes through Trinidad Lake State Park on the way out and again on the way back, and heads out into mesa country, with the Spanish Peaks northwest of town as the backdrop. The organizer says the roads are more than 90% maintained gravel and mostly rolling, and warns that the altitude and the climbing will still humble you, the 110 most of all.

The map shows the organizer's 2026 course lines, with the start, Trinidad Lake State Park and the crew points at Spanish Peaks Inn and 4 Corners pinned along them. The 2027 courses aren't out yet. The organizer gives no location for its Burro Canyon and Earth Mountain Farms aid stations, so you'll find them in the course notes below but not on the map.

On the back side of the 110, the organizer warns, cell service is limited or non-existent and it's 31 miles to an aid station. Download the map before you drive down. GPS shows where you are without a signal.

In 2026 you left Main Street at 9:30 AM, half an hour behind the pro and elite field, and followed pink and black tape and arrows. Trinidad Lake State Park at mile 6.6 is the first aid station and crew point, and inside the park the course takes 2 miles of South Shore Trail: rougher gravel with a few pitchy, loose climbs. Burro Canyon is next at mile 23.3, then Spanish Peaks Inn at mile 43.6, where your drop bag and your crew wait. Its cutoff was 1:50 PM, the first of three.

From there the aid stations are Earth Mountain Farms at mile 71.6 and Burro Canyon again at mile 90.3, which closed at 6:30 PM. The organizer doesn't publish where either one is, so neither is on the map. The last cutoff was 8:10 PM at Trinidad Lake State Park, mile 106.8, before the ride back into town.

In 2026 the 70 started at 10:00 AM and was marked with blue tape and arrows. Its first two aid stations are the 110's, at the same miles: Trinidad Lake State Park at 6.6, with the 2 rougher miles of South Shore Trail inside the park, and Burro Canyon at 23.3. You turn at 4 Corners on County Road 44, mile 34.6, where crews can meet you and the cutoff was 1:30 PM.

On the way back you pass Burro Canyon at mile 45.9 and Trinidad Lake State Park at 62.5, where the cutoff was 4:15 PM, then ride into Main Street. The course tops out at 7,585 feet and has no drop bags. Burro Canyon has no published location, so it isn't on the map.

The Rad Habanero 40

Up Burro Canyon Road and back down to town, with no cutoffs.

In 2026 the 40, marked in red, started last, at 10:30 AM. After Trinidad Lake State Park and its 2 rougher miles of South Shore Trail, you reach Burro Canyon Road and climb about 1,000 feet over about 10 miles to the course's high point at 7,221 feet. The Burro Canyon aid station is at mile 23.3, but the organizer doesn't say where it is, so it isn't on the map.

The organizer calls the return a lightning-quick descent, with Trinidad Lake State Park again at mile 40.8 before Main Street. There are no cutoffs or drop bags, and e-bikes race in their own category.

Registration and the Unbound coins

For 2026, registration opened to everyone on February 9. Deferred riders had a window from January 26, and Life Time members with six months of Club-Access membership got in a week early, from February 2. Early bird prices ran until August 25 ($190, $135 and $90 for the 110, 70 and 40), then $200, $145 and $100 up to race day. If you can't make it, you can defer to the next year until the expo opens on Friday, for half of that year's fee.

Finishers of the 110 and 70 can win one of 50 coins for Unbound Gravel. Half go to the top riders in each category and half to a random draw after the awards, and you have to be there with the qualifier tab from your bike plate. A coin guarantees a place in the Unbound 200 or 100, but you still pay the entry fee.

The pro and elite field is by application. Its purse pays the top five women and men $1,000, $600, $400, $300 and $200.

Getting to Trinidad

Trinidad is in the Purgatoire River valley at 6,025 feet, 13 miles north of the New Mexico line. The nearest big airports are Denver (215 miles) and Albuquerque (254 miles), and Colorado Springs (132) and Pueblo (94) are closer.

In 2026 packet pickup was Friday from 2 to 7 PM at Space to Create, with a second pickup on race morning from 7 to 9 AM. The rider's meeting was at 5:30 PM on Friday at 218 W Main St, the start and finish. Bring photo ID: you have to pick up your own packet. The city has camping at the Trinidad Community Center, about a mile from the start, with bathrooms and showers.

Crews and drop bags

Crews can help only at the official crew points, and a rider who takes help anywhere else is disqualified. Every course has Trinidad Lake State Park, on the way out and on the way back, where crews pay the park's day use fee. Take I-25 south to the Starkville exit, then County Road 69.1 and 18.3 to the south shore entrance. The 110 adds Spanish Peaks Inn (I-25 north to the Ludlow exit, then west on CR 44), and the 70 adds 4 Corners, about 9.6 miles up CR 44 from the same exit. If you drop out, someone has to collect you from one of these points, so keep a friend on call.

Drop bags are for the 110 only, and only at Spanish Peaks Inn. In 2026 you left yours on Friday from 2 to 7 PM at 218 W Main St, in a clear plastic bag from packet pickup with your name and bib number on it, and collected it at the finish by 7 PM on Saturday. Bags left after that went to local charities.

Weather and kit

Trinidad's September averages are a high of 79.6°F (26.4°C) and a low of 52.3°F (11.3°C) (NOAA, 1991 to 2020). The organizer says to plan for afternoons in the 80s, mornings and evenings in the low 50s, and rain, so bring a jacket.

It suggests you carry at least two liters of water or drink, two spare tubes, a pump, a phone and a GPS, plus lights if you'll be out past 7 PM. Gravel, cyclocross, mountain and road bikes are all allowed, but you have to finish on the frame you started on. Aero bars and clip-on extensions aren't allowed, and the only headphones you can wear are bone-conducting ones.

The Rad FAQ

When is The Rad Dirt Fest 2027?

Life Time hasn't announced the 2027 date. The 2024 and 2026 editions were both on the last Saturday of September (September 28 and September 26), and The Rad is the fifth round of the 2027 Life Time Grand Prix.

Is The Rad Dirt Fest part of the Life Time Grand Prix?

It was in 2023 and 2024, and it returns in 2027 as the fifth of the series' seven rounds.

Is The Rad an Unbound Gravel qualifier?

Yes. Finishers of the 110 and 70 can win one of 50 Unbound coins, 25 for the top riders in each category and 25 by random draw after the awards ceremony. The 40 mile has none.
