August 11, 2018 is the date for the Sammamish-Issaquah Challenge Race in Sammamish.  This FREE event is designed for the whole family to enjoy. Every child is a winner.  In 2018 the Sammamish-Issaquah Challenge Race will take place on SE 24th St near Discovery Elementary School, 2300 228th Ave SE, Sammamish, WA 98075. Be sure to register below if you plan to be a either Driver or Co-Driver.

Races run between 9AM and Noon, then FREE pizza. Race course setup starts at 8AM.  Driver instructions for those registered as “Drivers” are held before the races, between 8 and 9 AM.

The gravity car races allow those with developmental and physical disabilities the experience of a thrilling soap box derby-type race while riding in a car piloted by a typically developing driver who is 10 years old or older. The co-driver is a racer with developmental disabilities (no taller than 5’2” and 130 pounds or less).

Two cars, propelled by gravity, race down the street to the finish line. Each car has brakes so that the driver can safely stop it. Each racer with developmental and physical disabilities has the opportunity to race multiple times during each event.

After a morning of races, lunch is provided and an awards ceremony completes a day full of fun and memories.

Be sure to check out our website for updates and registration.
