Mapped race pages with stored route geometry and elevation evidence where available.
This guide includes 10 race pages whose latest source-backed race date falls in Spring and whose stored event-region value is Colorado. Nearby races by radius are not included. It does not infer annual recurrence unless that edition date is present.
