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 figure-8 loop with just 33ft 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 17 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.

CASH PRIZES

Compete for a share of the $1,300 prize pool with substantial cash awards for overall winners across all distances.
