Pedernales Falls is the first in the incredible 2026 Capt'n Karl's Night Trail Run Series. CKTS is the longest running night series in the country. These night-time races are incredibly well-supported and well loved! It's a must-experience event for new and seasoned trail runners. 60km, 30km, 20km, 10km and Sunset 5km.

While every racer will get some cool swag, May 14th is the deadline to get a shirt.

JUNE 27, 2026.

This will be the second event in the 2026 Capt'n Karl's Night Trail Run Series - held at Muleshoe Bend LCRA Recreation Area, approximately 40 miles northwest of Austin in picturesque Spicewood, TX. Muleshoe Bend is located on the scenic Lower Colorado River, Lake Travis region. This course is challenging, rocky, technical with 3094 feet of elevation gain. These trails are deceptively tough, with heat & humidity making Muleshoe Bend a worthy adversary. This is primarily due to the thick foliage & heavy woods, creating a peaceful environment & no wind. Get ready to sweat.

While every racer will get some cool swag, June 4th is the deadline to get a shirt.

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.
