Tricky Treater

Tricky Treater is an October 5K and 10K held in Alton Baker Park in Eugene, Oregon. From the start, it's a Halloween event: runners are encouraged to race in costume, with prizes for the best outfits. The event begins in the evening, offers the same base price for both distances, and provides a registration discount for runners 17 and under. Awards are given three deep in age groups from 10 and under through 80 and over, catering to families, regular local runners, and older competitors, as well as those primarily interested in the costume aspect. The course includes a small variation that distinguishes it from a typical park loop. In the 5K, runners decide whether to proceed clockwise or counter-clockwise, diverging after a gravel straight onto either the left path or straight onto Day Island Road, then encountering other participants going the opposite direction midway. The 10K follows the 5K loop twice, with participants running in opposite directions on each lap and selecting their initial direction. Volunteers distribute candy along the route in exchange for a trick, aid-station tricks are eligible for prizes, costume voting occurs by writing bib numbers on a board near the results tent, and Halloween-themed refreshments are available at the finish.
