Issaquah Schools Foundation Monster Mash 5K

The Issaquah Schools Foundation Monster Mash 5K begins at 4455 E Lake Sammamish Pkwy SE in Issaquah, Washington. This Halloween-season 5K supports local schools by raising money for programs serving students across all 27 Issaquah School District schools. It is designed as a family-friendly fundraiser, welcoming all ages and abilities. The course is professionally chip-timed for those seeking a specific time. The route is flat, paved, and out-and-back, suitable for first-time 5K runners, families walking together, and runners aiming for a personal best. Costumes are encouraged. Registrants receive free event photos and raffle tickets, with placement awards for top finishers. Schools can form teams, and the Issaquah Schools Foundation offers a cash prize to the school with the largest team, adding a local-school rivalry element to the Monster Mash theme.
