There's always an outlier race here or there, but generally, women can not hold on to men's fields at the pro level. I have seen many pro level women enter men's pro fields just to get the workout, and they get dropped every time unless the fields are tiny. Sure, in the "Pro" category at a local crit, Marianne Vos can beat most or all of the men, but in that same race if a top men's pro racer showed up, they'd lap the field.
