About the race
InHouse Ultra is an indoor Last Person Standing treadmill race held in St Petersburg, FL on February 20, 2027. The event uses Woodway treadmills and follows the backyard ultra format: competitors must complete 5 miles within each 60 minute loop. The facility is kept at a controlled climate, reported as 72 degrees with a light breeze and minimal humidity. The event includes spectators and continuous music, and it is live streamed on YouTube by Pacer Travel.
Participation in St Petersburg is limited to 14 athletes. The event is presented alongside a sister location in Salt Lake City, which is limited to 19 athletes.
Key race rules require each runner to remain on an assigned treadmill, wear a bib on the back, reset treadmill stats to zero before each loop, and keep incline at 0%. Nutrition and headphones are allowed, and towels are provided. Minimal attire includes running shoes, shorts, and a top. The winner is the last person able to complete the required 5 mile loop within the hour.
Additional rules include a 3-2-1 countdown before each round and a requirement to be on the treadmill in the 59th minute to avoid a DNF. Walking and bathroom breaks are allowed provided the runner remains on the treadmill until it stops. Certain actions such as leaving the treadmill while it is in motion, holding the handlebars while running, or impeding other runners can result in penalties or disqualification. Registration closes on February 20, 2027 and an entry fee is listed as 173.29 USD. Visit the organization's website for the most recent information.
