Austin Solstice Circuit Marathon
The Austin Solstice Circuit Challenge is a multi-distance running event at Pace Bend Park on Lake Travis, Texas on July 25–26, 2026. The course is a 1.64 mile figure-8 loop on smooth paved asphalt with minimal elevation gain (about 33 ft per loop). The route passes limestone bluffs, oak-covered hills, and provides repeated views of Lake Travis.
The Marathon course is USATF certified (code TX25015LAB). Aid is available at the start/finish hub every loop, and the course is fully marked with reflective markers for nighttime visibility. Packet pickup is offered the day before the event and on the morning of race day.
Pacer policy: personal pacers are permitted for the Marathon and 50K after eight loops and for the 52.7 mile solo after sixteen loops. Each pacer must register, pay a $15 fee for park entry and administration, sign a waiver, and wear an official pacer bib.
A 12-hour overnight relay is included for two-person teams. Relay transitions occur at the main canopy timing mat and teams are limited to two runners. Relay participants receive finisher medals, event swag, and access to the overnight aid hub. Parking near Kate's and Johnson Cove is limited to one vehicle per relay team.
