Why Choose This Race?
Fast, PR-Friendly USATF Certified Marathon Course (Boston Qualifier)
Unlike typical Texas summer ultras with brutal heat and technical trails, our smooth asphalt loop with minimal elevation gain creates ideal conditions for record-setting performances. This is a USATF-certified course: Certification code: TX25015LAB.
Evening Start Format
Race as the sun sets and July's magnificent Buck Moon rises over the limestone bluffs. Our strategic evening start times for longer distances mean cooler temperatures when you need it most.
Pacers Allowed
While we won't be providing official pacing groups for the Austin Solstice Circuit Challenge due to our size, we enthusiastically welcome personal pacers for both the Marathon, 50K and 52.7 Mile Solo events. Personal pacers can join Marathon and 50K participants after 8 loops and 52.7 Mile runners after 16 loops (approximately halfway points). Each pacer must pay a $15 fee that covers park entry, administrative costs, and an official pacer bib. Pacers need to sign a waiver and wear their designated "PACER" bib while on course. Runners are responsible for arranging their own pacers, but the loop format makes it particularly convenient for your support crew to join when you need them most. We find this flexibility is especially appreciated by first-time marathoners and ultra runners who benefit from personalized support during the challenging later miles as day turns to evening.
Pickup Information:
Saturday Packet Pickup:
Available from 4:30 PM to 6:30 PM.
Race Day Pickup:
For those unable to attend on Saturday or who prefer to pick up on race day, same-day packet pickup will be available Sunday morning from 5:30 AM to 6:30 AM.

August 8th, 2025.
This is the culminating event in the Capt'n Karl's Trail Series at one of the best privately owned adventure parks in all of Texas, the amazing Reveille Peak Ranch! This park is located 55 miles northwest of Austin in the historic town of Burnet. The amenities at RPR are first class & we will be taking advantage of this by providing our runners, spectators & volunteers with a series finale party. But first, runners will be treated to unique & spectacular geological formations. Navigating over large rock domes with amazing views, while tackling the most elevation gain of our four venues (3812 ft). This course really has it all….single track, exposure, tree-covered woods, hills & technicality. All to challenge even the most seasoned trail runner.
While every racer will get some cool swag, July 16th is the deadline to get a shirt.
What Is OUTLAST?
OUTLAST is a 6-hour trail endurance challenge where runners complete a 5K every hour, on the hour. Each lap must be finished within the hour to stay in the event. If you finish early, you rest until the next round. Miss a lap, and you’re out.
Complete all six rounds, and you OUTLAST.
This isn't just about speed — it's about pacing, discipline, and mental grit. Whether you're trying to survive all six or win your division, the challenge is the same: show up each hour, push your limits, and stay in it.
Each course is trail-based, with natural terrain, elevation, and unpredictable conditions. You’ll have time between rounds to recover, refuel, and refocus — but not much.
What You Earn:
4 laps = “Grit Earned” patch
5 laps = “Survivor” patch
6 laps = Premium “OUTLAST” medal
All participants receive a premium OUTLAST Tee.
Top male and female with the fastest combined 5K times at each event win the 1st Place OUTLAST award.
Finishers are ranked on the national leaderboard—and the fastest runner across all OUTLAST 6-hour events will be crowned National Champion and take home $1,000.
The 1st Place Male and Female 6-hour champions from this race will take home $1000 each. (This is separate from the national leaderboard prize money.)
By the end of the 2026-2027 tour, the top 100 best times nationally will be invited to also compete in the Outlast Championship in 2027.
Frequently Asked Questions:
Do I have to run all 6 laps?
Nope. Run as many as you can. If you complete 4 or 5, you'll still earn a patch. Only those who finish all 6 get the OUTLAST medal and leaderboard ranking.
What happens if I don’t finish a lap in time?
You're out. The next lap starts at the top of the next hour, and only those who completed the last lap on time can continue.
How is the race timed?
Each 5K is timed individually. If you complete all 6, your combined time counts toward the local win and national leaderboard.
Are these trail races or road?
Every OUTLAST race is on trail terrain — dirt, rocks, roots, and elevation. Sometimes some pavement and gravel.
Can I walk?
Yes, as long as you finish the 5K within the hour. But some courses are rugged, and time can sneak up on you.
Are there aid stations?
Yes. There will be water, basic hydration, and snacks at the basecamp/loop start. This is a cupless event — bring your own bottle or hydration system.
What should I bring?
Headlamps are required for all night race participants, trail shoes, hydration system, layers (weather dependent), fuel between laps, and grit.
Can I setup a tent?
Absolutely, bring your own aid station/tent setup.
Is OUTLAST for beginners?
Yes — if you're mentally tough. You don’t need to be fast, just consistent and ready to suffer a little.
How do I win?
If you finish all 6 laps and have the fastest combined time, you win your division (male/female). Winners are also added to the national leaderboard for a shot at the $1,000 national prize & title.

September 12, 2026.
Get your friends and family, and join in on this close to Austin and San Antonio lake party and trail run! The finish line arch will be as close to the edge of Lake Travis as we can get it (Austin area’s famed lake boasting over 9 miles of shoreline)! So when you finish you can cruise straight into the water to cool off and start your floating post-race party! This means, as the lake rises and falls each year, the distance will possibly slightly change, so we'll add "ish" to each distance...and that's perfect when everything and everyone stays mellow.
We’re incredibly thankful for the support of this race by the Travis County Parks Foundation!
While every racer will get some cool swag, August 18 is the deadline to get a shirt.
During registration, we are collecting $10 for one day of access to the park. If runners are staying for more than one day, they will have to pay additional amounts upon entering the park.

🐎 Rodeo Half-Marathon, Marathon Ultra and Backyard Ultra 🐎
Saddle Up. Run Hard. Run the Trails.
Earn the buckle. Be part of something gritty and real.
Race Weekend: March 13, 2027
Prices increase as spots fill.
🤠 Two Rodeos. One City. Endless Grit.
Come March 2027, while Austin celebrates cowboys, concerts, and competition at Rodeo Austin, a different kind of rodeo will unfold on the trails.
Welcome to the Rodeo Trail Run of Austin, where effort matters, the terrain tests you, and every finisher earns a custom rodeo-style buckle.
🦬 The Bull – Technical Course Segment
Some sections of the course are rocky, steep, and technical, earning its nickname for a reason. Runners will tackle a challenging course featuring:
Loose and exposed rock
Short but steep climbs and descents
Uneven footing that rewards patience and smart pacing
The elevation profile reflects frequent grade changes, making the technical segments as much about control and durability as speed.
This is a true test of:
Foot placement
Mental focus
Trail toughness
Respect the Bull — it adds up lap after lap.
Respect the Bull
THE MAIN EVENT: THE RODEO HALF-MARATHON & MARATHON ULTRA
This is a no-frills, honest trail half-marathon and marathon ultra on classic Texas Hill Country terrain. Rolling dirt roads, rugged footing, wide skies, and a course that rewards steady grit over hype.
Whether you’re racing hard or running strong, this is a course that feels earned.
Half Marathon and Marathon Ultra Details:
Distance: Half marathon and ultra marathon, 28 miles (trail)
Start Time: 9:00 AM
Fully stocked aid stations
Finisher recognition for every runner
Custom participant shirt
Rodeo-inspired atmosphere (without the chaos)
Field is capped. Prices increase soon.
Registered runners for the Rodeo Half Marathon (March 13) receive a free, trail-specific 12-week training plan, built for Hill Country terrain.
BONUS EVENT: 🔁 RODEO BACKYARD ULTRA (LIMITED FIELD)
At the Rodeo Backyard Ultra, the 4.167-mile (6.706 km) out and back course is the bull, and every hour, runners have to ride that bull again by completing a lap before the hour ends. When the next hour begins, the bull comes charging back out… and the runner has to saddle up once more.
Backyard Ultra runners will complete their segment as an out-and-back each lap, returning the same way they came. Expect the terrain to feel very different on the way back.
This is a small, gritty, invitational-style Backyard Ultra capped at 20-25 runners. If the field doesn’t fill, the event will convert to a timed endurance format.
Just like in the arena, this race tests endurance, grit, and heart, seeing how long you can "stay on."
The event keeps going until there's only one runner left: the Last One Standing.
Note: This is a sanctioned 'Backyard' meaning, runners' results are officially tracked in the global database and on the Path to Big's.
The 8-HOUR TIMED RUN.
Same 4.167-mile loop. Same 9:00 AM start. But instead of chasing a set distance, you're chasing the clock. Run as many loops as you can before 5:00 PM, that's 8 hours of trail, grit, and whatever you've got left in the tank.
Here's the rundown:
• Course: 4.167-mile loop at Grelle Recreation Area
• Start: 9:00 AM CDT
• Cutoff: 5:00 PM (8 hours sharp)
• Format: Completed loops only, run, rest, repeat
• Awards: Finisher buckle for everyone who completes at least 3 loops
• No participant cap
This sits right alongside our Half Marathon, Marathon Ultra, and Backyard Ultra, so whether you want a set distance or an all-day adventure, we've got a saddle for you.
Ride hard. Run harder. 🤠
Rodeo Backyard Ultra
How It Works
Each hour, runners start a 4.167-mile loop ("the bull").
Finish within the hour to stay in the race.
Any leftover time is your rest, until the bell rings again.
Miss the cutoff, and you're "bucked from the bull."
The race continues until only one cowboy or cowgirl remains standing.
Runner’s buckle awarded for completing 3 loops (13+ miles)
🐎 How It Works — With Marathon Option
If you don’t finish a loop within the 60-minute cutoff, you’re officially “bucked from the bull” in the Backyard division.
BUT…
Instead of heading home, you can drop down into the Half-Marathon Division and continue running loops until you complete 13.1 miles.
That means:
Backyard runners compete for Last One Standing
Dropped runners can still finish strong with a full half-marathon completion
No wasted miles. No early exit from the party. 🤠
Course & Experience Highlights
The Chute (Starting Corral)
Each hour begins in the "chute," where runners line up like rodeo riders waiting for the next bull. When the cowbell rings, it's time to ride.
The Roper's Turnaround
At the halfway point, runners must lasso a post before returning, symbolizing "roping the bull."
This ritual, called The Catch, keeps the cowboy spirit alive with every loop.
To verify, each runner moves their token (washer, chip, or bracelet) on a pegboard when they rope successfully, a simple, reliable self-check system.
The Watering Hole (Aid Station)
Recharge at the Chuckwagon with hydration, fuel, and friendly faces before the next ride.
🔔 The Arena (Finish Area)
When you finish a loop, ring the cowbell to announce your successful ride.
The echo of cowbells fills camp, a sound that says another bull's been tamed.
