Indoor Backyard Ultra Format

The InHouse Ultra is an indoor endurance event held in St Petersburg, Florida, that utilizes a "Last Person Standing" format. The competition takes place entirely indoors on Woodway treadmills within a controlled climate maintained at 72 degrees with low humidity. Participants compete in a specialized setting that includes energetic music and live spectators. The event is also live-streamed and features a simultaneous competition against a sister studio located in Salt Lake City.

The race follows specific distance and time requirements:

  • 5 miles to be completed every 60 minutes

The winner is determined when only one person remains capable of finishing the 5 mile segment within the one-hour time limit. The field is strictly limited to 14 athletes at the St Petersburg location.

Participant Rules and Regulations

Runners must adhere to specific treadmill protocols to remain in the competition. Each participant is assigned a single treadmill for the duration of the event. Before every round, the treadmill statistics must be reset to zero, and the incline is required to stay at 0%. Runners are notified of upcoming rounds via announcements at three, two, and one minute before the start.

Athletes must be on their treadmills by the 59th minute of each hour to avoid disqualification. During the run, participants are prohibited from holding the handlebars or receiving outside support. While walking and bathroom breaks are permitted, runners must wait for the treadmill to come to a complete stop before stepping onto the floor. Access to personal aid stations is only allowed after the 5 mile distance for that round has been fully completed.

Amenities and Requirements

The event provides towels for use on the treadmills. Runners are permitted to wear headphones and may consume nutrition while running. Standard running attire is required, including shoes, shorts, and a top. Visit the organization's website for the most recent information.
