InHouse Ultra

Immerse yourself in an unparalleled endurance challenge as you step into the world’s first and only “backyard ultra” treadmill race, taking place on February 20, 2027. This unique Last One Standing format unfolds indoors at a state-of-the-art facility equipped with Woodway treadmills, setting the stage for an intense battle of wills and stamina.
The competition is set against a backdrop of constant energy, with spectators cheering you on every step of the way. The air hums with lively music as runners push through grueling rounds to secure their place in this exclusive event. Each athlete must complete 5 miles within a strict time limit of one hour for each round, resetting their treadmill stats and starting anew at zero distance before embarking on another rigorous mile.
The race venue guarantees a comfortable climate year-round—maintained at a steady temperature of 72 degrees Fahrenheit with minimal humidity and a light breeze to keep you cool. This controlled environment ensures that your performance is solely determined by your physical prowess, mental fortitude, and strategic pacing rather than external conditions.
Competitors are divided into two studios: St Petersburg and Twenty One Run in Salt Lake City. The race features limited slots for 14 athletes at the former location and up to 19 participants at the latter, ensuring a tight-knit community of runners sharing this extraordinary experience.
Safety is paramount; amenities like towels are provided on each treadmill, allowing you to stay dry as sweat builds throughout your journey. Nutrition during runs is permitted, enabling you to fuel yourself effectively for prolonged efforts.
To participate, athletes must adhere strictly to the rules: wearing a bib at all times and ensuring it’s visible behind them, resetting their treadmills before every new round begins, maintaining zero incline settings, and avoiding any support from others except in cases of medical or mechanical emergencies. Walking breaks are allowed but require you to stop running entirely until reboarding the treadmill.
The winner is crowned as the "Last One Standing," completing a 5-mile run within an hour when all other competitors have been eliminated through disqualification or exhaustion. Announcements remind runners of critical deadlines, and penalties for infractions such as touching handlebars, interfering with others’ treadmills, or leaving your station prematurely can result in immediate elimination.
Join this pioneering event to test the limits of human endurance amidst a supportive community that thrives on pushing boundaries within controlled, indoor conditions. This race is not just about running; it's an exploration into what you’re capable of enduring when faced with relentless challenges and unyielding competition.
