Return of the Bull You’ve been penned up all year. It’s time to break the fences. Kick off your Labor Day weekend with an unforgettable trail running experience at McKinney Roughs Nature Park, a stunning 1,140-acre preserve just 13 miles east of Austin along the Colorado River. Choose from seven events that wind through the park's rolling box canyons, wildflower meadows, and towering loblolly pine forests. This is Central Texas trail running at its finest. You'll traverse four distinct ecosystems. Post Oak Savannah, Blackland Prairie, East Texas Piney Woods, and a lush riparian corridor, all in a single race. Expect technical single-track, scenic river overlooks, and the kind of terrain that makes every mile an adventure. THE RIO COLORADO 250 The river you run above on Saturday is the one the series is named for. Two hundred fifty kilometers with Fit Foundation in a calendar year earns the Rio Colorado 250 buckle. Not instead of your race hardware. On top of it. Every kilometer counts, including the ones you cover in the timed events. That last part matters. The 8-Hour Solo doesn't credit you a fixed distance. It credits you what you actually walk, run, and grind out between seven in the morning and three in the afternoon. Some of you will put more on the board in one day than a 50K would give you. Here is the calendar. Autumn Harvest on October 10. Fields of Gold on October 24. The Colorado River Run on November 27. Star of Texas on December 13. Four events in nine weeks. September is the last quiet place to start. The count begins at McKinney Roughs. Return of the Bull marks the second chapter of the Rodeo Trail Run Series, following the inaugural Austin's Rodeo Trail Run at Grelle Recreation Area. All half-marathon, marathon, and 50K finishers receive a custom rodeo-style belt buckle and event shirt, the signature swag of the series. Unleash the grit. Master the Roughs. Run Free.

STARTS 7:15 AM · 8 HOURS GAUNTLET: LAST RUNNER STANDING Stop 3 of 4 · The Proving Ground Beat September. Own October. Labor Day Weekend · 10:00 AM Start · Texas Labor Day weekend is summer taking its last swing at Texas, and this is the stop where you swing back. One 2 mile loop, all race. From the 10 AM bell you run it once an hour. Twice from 6 PM. Three times from 2 AM. At 10 AM Sunday it locks there: three laps, 6 miles, on the hour, for as long as anyone keeps answering the bell. The first eight hours are deliberately generous, and in September that is the whole idea. One lap an hour is walkable in the worst heat of the day, which means the field is still intact when the sun goes down and the race actually starts. Everyone gets to the interesting part. What happens after that is up to you. Heat is the one variable an entire field feels at the same time, so nobody out here is having an easier day than you are. The corral becomes shade tents and ice and crews trading tricks between bells, and a loop that felt like a fight at four in the afternoon turns into a different loop entirely once the sun drops. Run the hot hours patiently and the night belongs to you. Runners heading for the season finale treat Labor Day as the proving ground. It is the last data point before Fields of Gold and the one that tells you the most about what you will have left in October. Everything Labor Day teaches you, you get about six weeks to act on. 2 MILES One Loop, All Race The course never changes. Only how many times you run it before the bell. 1 → 3 Laps Per Hour One more lap added every eight hours. You do not get the easy version back. 96 MILES Just To Reach The Wall Reach it in September and you have done something almost nobody in the field will. 60 MIN The Hour Doesn't Stretch Heat buys you nothing. The bell rings on the hour whatever the thermometer says. How it escalates Same loop every hour. One more lap of it every eight.
