Tricky Treater

10/25/2026
Alton Baker Park, Eugene, Oregon
It's time to celebrate the season - come in costume ready to compete for prizes! All 5K participants get to decide which direction they want to run on the 5K course - clock-wise or counter-clockwise. All participants start together and then either veer left at the end of the gravel straight, or straight ahead on Day Island Road. Participants will be able to see each other going the opposite direction midway through the course. If you're doing the 10K, you'll do the 5K loop twice, going in opposite directions each time - you can decide which direction you run first. Yes, there's some strategy involved, and of course fun!
