This is a strawman. Nobody is saying women are “dumb at maps”, and nobody serious thinks Q angle is the only thing that matters. The point is much simpler: orienteering is not just map-reading. It is timed racing across terrain while navigating under physical and mental load.
At competitive level, orienteers run. They climb, descend, accelerate, recover, make route choices while tired, and cover ground quickly. That is why British Orienteering itself recognises Foot Orienteering and Ski Orienteering as sex-affected sports, where strength, stamina and physique create a competitive disadvantage for female athletes if the female category is not protected.
A woman winning an ultra outright is brilliant, but it does not disprove male advantage in running sports. It shows that at the extreme end of endurance, in particular events and conditions, women can sometimes close the gap or even beat the men in that race. That is not the same as saying there is no sex-based performance difference.
Across standard running distances, males generally outperform females. One 2024 review summarised the male advantage from 100m to marathon as around 7% to 14%. In ultra-endurance events, the gap can narrow, but the evidence does not show that women generally outperform men.
That actually supports separate categories. Male and female bodies have different performance profiles. Males generally have advantages in speed, strength, power, oxygen-carrying capacity, muscle mass and stride mechanics. Females may have relative advantages in some extreme endurance contexts, including pacing, fatigue resistance and fuel use. But ordinary orienteering is not a 200-mile ultra. It is a timed navigation race where covering ground quickly still matters hugely.
Protecting the women’s category does not mean women are bad at maps. It means women are entitled to fair competition, ranking, representation, medals and records against other female athletes. If there were genuinely no sex difference in competitive orienteering, British Orienteering would not need W and M classes at all.
And the new policy is not a “ban” on participation. The unrestricted category remains open, and additional unrestricted entry classes can be offered. What has changed is that female prizes, rankings and titles are reserved for female competitors. That is exactly what a female category is for.
