SPOKANE, Wash. -

Each year, at least 50,000 people run, walk or even wheel their way through the Bloomsday course, and its become an annual tradition for wheelchair athletes Scott Parson and Edwin Figueroa.

“The course is really challenging and the field is great, a lot of competition,” Parson said.

Parson and Figueroa touched down in Spokane Friday fresh from California. Parson has won the wheelchair race the last two years.

“The older I get, the younger they get so it's going to be tough this year,” he said.

This year is Parson's 15th Bloomsday while Figueroa has raced it a dozen times. Each year they always mark their calendars for this race.

“The group of people that put the race on, they really make it good for all the wheelers to come back," Parson said.

The wheelchair athletes are greeted at the airport and then taken to their hotels, with equipment in tow, by STA.

“They see everybody equal, from elite runners to able bodies, it's a good group,” Figueroa said.

While they're looking forward to the race, they're both like every other athlete getting ready for the course. They're dreading Doomsday Hill.

“The course, a lot of pain, brutal and danger, you have to know what you've been doing," Figueroa said.
