This guide includes 33 ultramarathon race pages whose latest source-backed race date falls in Winter. Smaller date-distance groups are not published as standalone pages until they clear the coverage threshold.
13 winter ultramarathons currently have stored route geometry. Route traces appear only when stored geometry exists.
Featured races are ordered by race date first, then by available evidence such as route geometry, elevation profiles, route metrics, cost data and race-character tags.
