As at July 2025, British Orienteering’s Trans Policy states
At all competitions, events and activities other than those listed as Identified Major Events, trans people will be able to compete in the sex category aligned to their gender identity. However, it is recommended that any athletes participating in the female category who would not be eligible to compete in the female category under the IOF Transgender Policy should not be eligible to win titles, medals, prizes or trophies, either individually or as part of a team. Competitors may assume that a competition will be following this recommendation unless the organiser has explicitly stated otherwise.
This creates a problem for league competitions such as UKUL and UKOL, which award titles, medals, prizes or trophies based on positions at a series of events. A trans woman competing in a female category would reduce the points scored by anyone finishing below her and could affect the overall outcome of the league, even if she were ineligible herself for the titles, medals etc. The problem is particularly acute if competitors do not need to score all events, as in the various Urban Leagues.
The policy quoted above makes it clear that trans women who would not be eligible to compete in the female category under the IOF Transgender Policy should nevertheless be able to compete on the day in the female category of a league event.
Trans women are therefore welcome to enter female Urban League categories. However we do need to be able to identify them so that, when results are uploaded to the Urban League database, their results can be excluded. In order to do that, we need to ask all competitors entering female categories whether or not they were assigned female at birth.
