Warm up for your Fall City Day celebration with the annual Fall City Day Fun Run, starting at 9:15 a.m. Saturday.

Whether you choose the 5k or 10K — there’s also a 1K for kids starting at 9 a.m. — you’ll enjoy a pancake-flat and fast race course, so be prepared for a personal best time, organizers say.

“We have prizes for overall men’s and women’s first, second and third-place finishers for the 5k and 10k races,” said Kirk Harris, one of the race organizers each year. “In total there are 82 different categories for awards.”

The 10k and 5K races are USATF certified and sanctioned courses along country roads that cross the Snoqualmie River, with water stations near the turn-around points for both. Races are chip timed by Rogue Multi-Sport; top-three awards will be based on gun time, not chip time.

Online registration, at http://www.fallcity.org/run.html, ends Wednesday. In-person registration can be done one day in advance, 5 to 8 p.m. Friday, June 10 at Fall City Elementary School, or on race day, 7 to 8:30 a.m. Saturday, June 11 at Olive Taylor Quigley Park, 33512 S.E. Redmond-Fall City Road.

The start and finish line for all races is in front of the Farmhouse Market, across from the park. Winners will be announced at 10:45 a.m. at the park.

Race proceeds benefit the students of the Snoqualmie Valley School District. Each school receives a percentage of the total based on the number of participants who supporting each school.

“Over the past three year’s races, the all-volunteer organized event has donated all of its proceeds ($31,200) to Snoqualmie Valley Schools and youth groups,” said Harris.
