SPOKANE, Wash. -- More than 50,000 runners and walkers will converge on Downtown Spokane Sunday for Bloomsday.

Here are five things you need to know about the race (even if you aren’t taking part):

1. You still have to run Doomsday Hill: Construction on the Pettet Drive project was completed just in time for the race. The course is the same as 2016

2. Downtown Spokane roads will be closed: The start and finish line will close at 5:00 a.m. and reopened at 2:00 p.m. Other streets on the course will close at 7:30 a.m. and open once the final walkers pass. City leaders expect Riverside west of Monroe to open as early as 11:00 a.m. and as early as 2:00 p.m. for Broadway west of Monroe.

3. Use other roads: If you want to go Downtown Sunday morning you should use Ash, Maple, Division/Browne and Hamilton. Those streets will be open all day long.

4. Carpool or take the bus: Parking will be available at the Spokane Arena and dozens of lots Downtown. STA will also have four Bloomsday express shuttles from satellite locations at Northtown Mall, Spokane Valley Mall, Ferris High School and Red Barn in Cheney. You can pay $1.50 each way on the day of the race or pick up a pass when you register for the race or at check in.

5. New t-shirt pick up area: Runners will be routed down Main Avenue to pick up their shirts after the race. Water stations and displaced children pickup will be near Wall Street. Normally runners would go down Spokane Falls Boulevard and into Riverfront Park for these services.
