I'm just saying except maybe at the very top of the sport and by that I pretty much mean world marathon there are far stronger fields in men's races at almost every race. And even there it is debatable. The bottom line is there is just a much larger number of males training at a high level and competing for those top spots. This can be seen at almost all races the gap between the top male and those out of the money is significantly smaller than the top female and those out of the money. But I feel like if a race director put more money on one side they would be crucified by the PC police.
I think gender battles are gimmicky and aren't a solution. They usually only affect the top male and female and go based on race history rather than who has a better performance. Plus they take away from the spirit of racing since rather than competing against just those you toe the line with you also have to beat someone who starts who started ahead or behind you by a certain amount.
I don't know if anyone has any creative solutions to this issue but I think given the demographics of elite runners moving more money to the men's side would be reasonable.
