Arc'teryx Shakeout Run

Arc'teryx hosts a free three-mile shakeout from its Rush Street store on the Saturday before the race. Doors open at 7:30 AM for check-in, followed by welcome remarks and marathon tips from Olympian Chirine Njeim and coach Emily Hutchins. At 8:30 AM, the all-paces group heads out on an out-and-back covering portions of the marathon course. Snacks, drinks and a DJ keep the gathering going after the run. Registered runners also receive a complimentary climbing session at First Ascent West Loop from noon to 3 PM, and advance registration is requested because space and swag are limited.
