What to expect

Recurring sessions can change because of weather, holidays, venue operations, route conditions, or organizer availability. Check the same-day status before travelling.

Participant preparation

Riders should bring a roadworthy bicycle, helmet, hydration, repair essentials, and clothing suitable for the course and weather. License requirements, route files, feed zones, cutoffs, and start procedures vary by event.

Before you go

• Confirm the final date, local start time, check-in or rollout time, and exact meeting point.
• Review registration deadlines, entry fees, ticketing, age or skill restrictions, waivers, and refund policies.
• Check weather, surface or ice conditions, transport, parking, accessibility, rentals, and venue rules.
• Use the organizer’s latest post—not an older calendar copy—as the final authority for schedule changes.
