Each race is its own battle. Together they determine who rules the frontier.
Rugged, technical Hill Country terrain designed to test early-season limits. The most demanding course on the circuit — and it rewards you for it.
Texas Hill Country at the edge of summer. An unforgiving late-May sun that challenges the state's most serious endurance runners.
Race Page & Registration →Set deep in the iconic lost pines and sandy loam. The perfect autumn crucible to build your series yardage heading into the final standings.
Race Page & Registration →Backyard ultra scoring is simple. The series layer adds strategy. Here's exactly how your loops turn into the championship title.
To appear on the official Master Circuit Standings, you must record completed loops at a minimum of two of our three circuit events. Run one event and your points still bank — but your name doesn't unlock on the master leaderboard until you hit that second starting corral.
Your score is based entirely on distance — not position, not pace. At Austin's Backyard and Big Bastrop, every loop you finish before the 60-minute bell earns exactly 1 point.
Not all trails are equal. Because of the brutal terrain and sheer physical toll of the Rodeo Backyard Ultra, every completed loop is worth 1.5 points. Grind out a 50-miler (12 loops) at Rodeo and you're banking 18 points — not 12.
| Loops | Distance | Austin / Bastrop | Rodeo (1.5×) |
|---|---|---|---|
| 4 loops | 16.6 mi | 4 pts | 6 pts |
| 12 loops | 50 mi | 12 pts | 18 pts |
| 24 loops | 100 mi | 24 pts | 36 pts |
The deep-mileage battles that happen when the field thins out deserve extra weight. Flat bonus points go to the last two athletes — not affected by the Rodeo multiplier.

If you want to win the circuit, you can't cruise through one event. You need massive yards — and you absolutely want to take advantage of the point-heavy Rodeo course to launch yourself up the standings early in the season. The crown stays up for grabs until the final yard is run.
Register for all three events as a bundle and lock in your spot on the Last Frontier Circuit master leaderboard.

This race spans more than one sport — here’s a guide to each, so you can understand what’s involved and decide if it’s the right fit. For course distances, logistics, and race-day specifics, always defer to the race organizer’s event page.
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
Running off-road — dirt, singletrack, and mountain paths — from 5Ks to ultras. The terrain, not the pace, is the whole point.
