Different ground.   A backyard ultra is not a distance. It is a shared hour and a binary outcome. Cumulative mileage challenges throw out both and keep the vocabulary. This one keeps the hour. You run on your own ground, wherever that is. You start when everybody else starts. You are out when the clock says you are out. One corral, scattered across the country. FOURTEEN OF THE TWENTY FOUR HOURS ARE DARK. DATESaturday, December 19, 2026START8:00 AM CENTRAL, ABSOLUTELOOP4.167 miles, hour on the hourCEILING24 loops / 100.008 milesENDS8:00 AM Central, Sunday, December 20FIELDUncappedSURFACEAny. Road, trail, track, treadmill.SERIES POINTSNone. This race sits outside the circuit. The Clock Everything runs on Central time. If you are in Denver you start at 7:00 AM. If you are in Boston you start at 9:00 AM. The whole point of a corral is that everybody is on the same hour, and a race that lets each runner pick a start time is not a corral, it is a set of solo time trials that happen to share a logo. Each loop opens at the top of the hour and closes at the top of the next one. •Start before the top of the hour and you are out.•Fail to cover 4.167 miles before the next top of the hour and you are out.•Whatever is left of the hour is yours. Eat, sleep, sit down, stare at a wall. No partial credit. No banking. Six miles in hour 4 buys you nothing in hour 5. Rest is the only currency in this race and the clock is the only thing selling it. The Ground Any ground. A neighborhood block, a park loop, a track, a trail, a treadmill. Change surfaces between loops, change locations, drive somewhere if the hour allows it. Most people will run the same 4.167 loop twenty four times, which is exactly what the format asks of you. Treadmill loops are legal and are marked with a T in the results. That is disclosure, not penalty. A treadmill takes out weather, darkness, footing, and navigation, and a 2:00 AM treadmill mile and a 2:00 AM gravel mile are not the same mile. Crew and pacers are unrestricted. You are running against the hour, and there is nobody standing next to you to gain an advantage over. The Finish Reach loop 24 and you finish. Everybody still standing at 8:00 AM Sunday finishes together and is listed together. There is no last one standing here, because a ceiling and a last one standing cannot both exist. The version of this race without a ceiling asks people to keep going, alone, in their own neighborhood, in December, with no race director, no timing tent, and nobody watching for the signs that mean stop. The ceiling is deliberate. It is stated up front. It does not move if two people are still going. The assist goes to the last runner out before the final loop closes, same as it always has. Logging Your Loops Every loop is logged in THE YARD. Connect Strava once and your loops land in the corral automatically with distance, elapsed time, and start timestamp attached. Manual GPS file upload works too. Screenshots do not, because a screenshot has no timestamp anybody can check. Join the Fit Foundation Texas Club on Strava to see loops post live as the corral runs. Registration here does not put you in the corral. THE YARD does. Set it up the day you register, not at 7:40 on race morning. This is an honor system race, and here is what is on offer to somebody willing to cheat: a coin, and a line in a table saying they ran a distance they did not run. No prize money. No series points. No Bronze Ticket. Nothing that flows anywhere at all. The format has always run on the fact that the people it attracts are not interested in that particular lie. Hardware LOOP 1Patch. Everybody who starts the clock and logs a loop gets one, mailed after the race.12 LOOPS50.004 miles. Finisher coin, struck for this race only.24 LOOPS100.008 miles. Coin, plus registration credit toward any 2027 Last Frontier Circuit race. The patch is not a participation trophy and it is not a consolation prize. In this format going out is the ordinary result. It happens to nearly everybody, at every race, every time. The patch says you stood in the corral and took the hour on, which is the only part of this that was ever up to you. No buckles. The series buckle is earned in a corral with a race director standing at the bell, and handing out the same hardware for a logged GPS file would hollow it out for every runner who already has one. That is not a knock on virtual running. It is the reason the buckle means anything. Entry THROUGH OCT 31$25NOV 1 TO DEC 12$30DEC 13 TO DEC 17$35REGISTRATION CLOSESDEC 17, 11:59 PM CENTRAL Eighteen and over. Two ways in: the full event, or the one-loop entry below. In a backyard ultra you do not pick your distance beyond that, the hour picks it for you. One Loop Entry This is not a shorter race. It is the first hour of the same race. Same corral, same 8:00 AM Central bell, same 4.167 mile loop. You start when everybody starts. You stop after one loop, which is what happens to most of the field anyway, just earlier. If loop 1 feels good, you can upgrade to the full event any time before the loop 2 bell. No re-registration, no separate check-in, just keep going. One Loop entrants and full-field entrants are listed in the same results table, because that is the entire point of a shared corral. ENTRY FEE$15, flat, no date tiersDISTANCEOne loop, 4.167 milesHARDWAREPatch. No coin.UPGRADE WINDOWOpen through the loop 2 bell   Read This Before You Register There is no course. Nobody measured it, nobody marked it, nobody inspected it, and nobody is coming to find you on it. There is no aid station, no marshal, no sweep, and no medical support at any point. You choose your own route and you are solely responsible for it, including traffic, park hours, trespass, footing, and roughly fourteen hours of December darkness. Tell somebody where you are running. Then tell them again on Saturday. The Week Everybody Scatters The week before Christmas is when the field comes apart. You are at your in laws in Ohio. You are in a hotel in Phoenix. You are home in a town with no trail system and no start line inside four hours. That is the only condition under which a virtual corral is the real thing rather than a lesser copy of one. Everybody is somewhere else. Everybody is on the same hour anyway. Canyon of the Eagles is thirteen days later. Rodeo Trail Run is in March. Whatever happens here, there is a real corral waiting. Same hour. Different ground.
