I've received an email today regarding the decision to include transwomen in these races.
After much reflection and listening to feedback from the trail-running community over the past month, we have made the decision in collaboration with SheRACES to change our policy, so that we include transgender women at these events. We recognise that transgender women also face barriers in competing in mixed events and with these events we have the opportunity to create a unique environment, where all women are encouraged to participate – aligning with our original mission.
This looks like capitulation to the demands of a very vociferous group of very entitled males and those who advocate on their behalf. I've replied expressing my disappointment that the event is now mixed sex but excludes all my male running friends, decent men who would not dream of gatecrashing or sabotaging a race intended for women.
