The Last Frontier Circuit - Texas Backyard Ultra Series
No finish lines. No fixed distances. Just one 4.167-mile loop every hour until only one Texan is still standing.
What Is This?
A season-long championship across Texas, brought to you by the team behind Run A Backyard Ultra. The Last Frontier Circuit is a multi-venue points series that crowns the ultimate endurance champion of the Lone Star State. Complete two or more events, stack your yards, and climb the master leaderboard.
- 2+ Events Required: Compete in at least two circuit races to unlock your spot on the master leaderboard.
- 1.5x Rodeo Multiplier: The brutal Rodeo terrain pays 1.5 pts per loop. Stack your advantage early.
- +5 Last One Standing Bonus: Win any event and earn five bonus points.
The Circuit Lineup
Three landscapes. Three seasons. Three kinds of suffering. Each race is its own battle. Together they determine who rules the frontier.
- Spring: Season Opener · The Grit Rodeo Trail Run Backyard Ultra
Spicewood, Texas. Rugged, technical Hill Country terrain designed to test early-season limits. The most demanding course on the circuit — and it rewards you for it. 1.5x Points Per Loop - Late May: The Foundation Austin's Backyard Ultra
Turkey Bend Recreation Area. Texas Hill Country at the edge of summer. An unforgiving late-May sun that challenges the state's most serious endurance runners. - Autumn: The Loam Big Bastrop Backyard Ultra
Lake Bastrop. Set deep in the iconic lost pines and sandy loam. The perfect autumn crucible to build your series yardage heading into the final standings.
More venues to be announced — the frontier keeps growing.
Series Scoring: The Last Texan Standing
Backyard ultra scoring is simple. The series layer adds strategy. Here's exactly how your loops turn into the championship title.
- The Two-Race Minimum: To appear on the official Master Circuit Standings, you must record completed loops at a minimum of two of our three circuit events.
- The Math: 1 Loop = 1 Point: 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. Example: tap out after 12 hours (the 50-mile mark) and you walk away with 12 points.
- 1.5x The Rodeo Multiplier: 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 (1.5x) |
|---|---|---|---|
| 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 |
- Bonus Points for the Final Survivors: Flat bonus points go to the last two athletes — not affected by the Rodeo multiplier.
- +5 Last Person Standing: Win the race. Earn five bonus points on top of your total loop score.
- +3 The Assist: Complete the second-to-last loop. Three bonus points for making it a battle.
The Strategy
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.
