Train for something.

Races drop off this list the day they are run. 67 have no announced date yet; those say which day of the month the race normally falls on, and whether that is from a check or an estimate. Races with a confirmed date open a page showing how long a build for each distance takes and the week it would start; the rest go straight to the organiser, who is the only authority on whether a race is open.

The list refreshes every 1 hour. It is a starting point for a plan, not an entry service — OLTRA does not sell race entries and takes nothing from the organisers listed here.
