About this race
This 6th annual event combines running with a sweet tooth. Run a traffic-free course through Seward Park and along Lake Washington. Celebrate with a post-race ice cream sundae, complete with all the toppings, even for your four-legged friends. Don your 'Sundae best' for the costume contest and try to 'beat the ice cream' to the finish line. A 'banana split halfway mark' with whipped cream awaits at this Sundae Runday.
