Twilight at the Bay (University Place, WA)
Twilight at the Bay is an evening running event on the Chambers Bay Loop Trail in University Place, Washington. The event includes a 5k, 10k and half marathon and is USATF sanctioned. The course follows the paved Chambers Bay loop and runs clockwise.
The loop is paved and combines flat sections, inclines and switchbacks. Each loop has about 220 feet of elevation gain. Distances and loop counts:
- 5k : one loop
- 10k : two loops
- Half marathon : one unique longer loop plus three additional loops
Aid stations: one aid station is located just over half a loop (about mile 1.7) and another is at the Start/Finish area (about mile 3.1). The Start/Finish area also handles packet pick-up and day-of registration; advanced packet pick-up is not offered. Drop bags may be left at the Start/Finish.
Parking is in the main Central Meadows lot or the North Driving Range lot; signage directs participants to the Start/Finish. Strollers are permitted but must stay toward the back behind competitive runners for safety. Dogs are not allowed due to USATF certification and insurance requirements. All participants receive custom Run Super swag and a finisher medal. The event enforces a strict no-litter policy; leaving trash on course can result in disqualification and future event bans.
