This guide includes 179 race pages whose latest source-backed race date falls in May 2027. Smaller year-month groups are not published as standalone pages until they clear the coverage threshold.
86 may 2027 races 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.
