Bus & Bike Loading at Finish Line
(Location)
When should I load my bike? As soon as possible at the finish line to avoid transportation delays. Buses often arrive in Seattle before the bike trucks do. All bike trucks and buses load on NE 9th Ave, on the west side of the DoubleTree Hotel. Saturday and Sunday are the only days that you can load your bike. If you are returning to Seattle on a Monday morning bus, you must load your bike on Sunday. There will be a designated "Monday" arrival truck.
What do I need to pick up my bike in Seattle? Leave your bike number affixed to your bike; you or someone with a your rider bib number (or picture of it) will need this to pick it up in Seattle.
