Race Calendar

How this page is kept up to date

We review organiser announcements and official entry platforms. Each race shows when its information was checked. The clock updates published entry windows in the race’s local time; a date-only deadline runs to the end of that local day. This does not check remaining places, postponements or new announcements. Overseas, general and qualifying entries can have different deadlines and eligibility. Use the labelled entry link and confirm the applicable distance and conditions with the organiser. Dates labelled provisional still need organiser confirmation. An official calendar confirms the published schedule, not registration availability. We never roll a previous edition’s entry dates into a new year.
