From the local race organizers of the Portland Trail Series and the Volcanic 50, we’re excited to tell you about a brand-new event coming on Saturday, April 5, 2014: This new event, the Stubby Chase, involves trail running and mountain biking in a relay-like format. You and your teammate have 13 miles to cover using your feet and one bike between you, getting to 10 checkpoints before crossing the finish line.
