Ruosniemi Backyard Ultra

Ruosniemi Backyard Ultra is run in Pori, Finland, on the fitness trail beside Ruosniemi Ski Resort. It follows the Backyard Ultra format: runners start a 6.706 km loop every hour, and anyone who fails to finish the loop inside the hour is out. The race keeps restarting on the hour until only one runner can complete one more loop than everyone else. It is not really about raw speed; the format rewards patience, pacing, eating, resting, and the ability to start again when the body wants to stop. The route is built from three smaller loops of 2,236 meters, each using the cross-country ski track area near the race center. Runners pass through timing on the first two sub-loops, complete the third to make the full yard, then wait for the next hourly start if they have time left. The course is marked with yellow ribbons around Easter. The race is organized by Spiidi.Net, and its Silver Ticket status gives the winner a place on Finland's team for the Backyard Ultra World Championship. Recent results show how tough the format gets: the winner reached 25 laps, or 167.6 km, while the runner-up stopped at 24 laps after running the last ten hours with a sore knee.
