HOW HARD IS IT?
On a scale from 1 (delightful) to 10 (brutal), Summit to Sound sits around a 7 — challenging enough to earn the finish but fun enough to enjoy the ride.
BIKE AND TIRE REQUIREMENTS
Summit to Sound includes a mix of surfaces: paved roads, packed gravel, and unpaved service roads.
Recommended setups include:
• Gravel bikes
• Cyclocross bikes
• Mountain bikes
• Road bikes with wider gravel tires
Recommended tire size:
• Minimum: 35mm
• Ideal: 38–45mm
Rule of thumb: If your bike can comfortably handle a long gravel trail ride, it will work for Summit to Sound.
EVENT DAY LOGISTICS
Optional Party Bus (shuttle) departs 7:30 AM sharp from Seacrest Park in Seattle and transports riders and bikes to the start at Hyak - the shuttle will not wait for late arrivals.
S2S is tailored for Intermediate to experienced cyclists, offering a challenging route that may not be suitable for beginners.
E-BIKES WELCOME
Class 1 electric bicycles only please.
CARRY ESSENTIALS
While S2S is fully supported, anticipate remote sections where support may be delayed. Come prepared with water, snacks, and basic repair tools to self-manage minor issues and ensure a seamless ride.
WHAT HAPPENS IF I CAN’T FINISH?
Riders who cannot complete the course will be assisted by support vehicles when possible. Because portions of the route are remote, pickup times may vary.
