The Tygh Valley Infinity Ultra is a "backyard" style ultra. How many 5K laps can you run? The clock starts every 40 minutes!
Led by Fairhaven Runners' staff and volunteers, runs are 20 minutes out and 20 minutes back on two key routes divided into groups by pace.
Join Fleet Feet in Capitol Hill or Ballard for 3 to 6+ mile all paces runs.
