So – women have limitations in some areas and men have limitations in others areas. Now all that is left is to measure every possible issue that faces runners and list whom it effects the most.
Then we'll know if one gender has an inherent genetic advantage over the other.
Or we look at the abundance of race times available, the fact that many men every year run faster than the women's world record in any distance I can think of. That's pretty convincing evidence about who has the advantage.
Train hard and train right – and you'll outrun many other people – no matter your or their their gender.
That's precisely the case for 99+% of the running world.
