Race Preview: 2021 Tygh Valley Infinity Ultra


The Tygh Valley Infinity Ultra is a unique event with no designated total distance. Instead, this is a “last one standing” event. This X-Dog race will be a live event at the Wasco County Fairgrounds. How does this endurance event work? Participants will run a 5K loop. A new loop will start every 40 minutes. All who finish in under 40 minutes may opt to run the next loop. Participants will run this 5K loop repeatedly until opting out of another or until participant cannot finish a loop in under 40 minutes. The last person standing . . . or running . . . will receive a giant trophy, while the rest of the competitors will walk away with a DNF medal to commemorate their participation.

Plan on a fairly flat loop with a variety of running surfaces. There will be some on course snacks/hydration, but it will be limited this year, so it is recommended you bring your own, as well.  Most of the course is lit, but if you plan to run loops into the night, you might want to bring a headlamp. Toilets will be available at the start/finish and there will be a dry location to store any extra clothing/gear/snacks you need. Be sure to pack everything you think you might need. This promises to be a long day . . . for some!

This event will support the Maupin School athletic and band programs. X-Dog Events will also be working with local 4H organization.

Camping is available within walking distance of the start/finish. See website for information regarding this option.
