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.
Carpe Diem 60
One Hour. One Sunrise. Start your day with purpose.
Carpe Diem 60 is a 60-minute sunrise endurance challenge on this out-and-back course. At 6:00 AM, you’ll have one hour to cover as much distance as possible with early morning focus. Most Distance Covered Wins

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.
