I completely agree. many people on this forum don't seem to understand how having some type of eating disorder in women's specifically running creates this f**ked up, twisted storm that YES will lead to breakthrough performances- albeit for only around a year or so. I want to go over why it happens in women's distance running/XC so much:
Let's say approximately 60% of the field has a regular menstrual cycle in a high level NCAA cross country meet (god it's probably lower than this).
That means the 60% of the field that does menstruate regularly will be at roughly 16-20% body fat (probably lowest you can go for period to occur) or higher... if you have a girl running at 10% or 11%- usually only achieved via disordered eating- that is a massive difference, and performance advantage over any girl who is healthily menstruating. These menstruating girls happen to be a decent portion of the field.
This anorexic girl can cross train, run less mileage, and STILL crush competition that she healthily would not have otherwise. i.e Healthy girl running 60mi p/w versus anorexic girl running 30 mi p/w, the anorexic girl will probably win just due to the insane advantage of having unnaturally low bf% (even though I hate to admit it and it's really sad).
To juxtapose with men's running- this won't happen as often. Partly because menstruation doesn't occur for this group ! Most XC guys are already really lean compared to the average person their age. There's not as much room in body fat% variation to create that difference via disordered eating (probably like Valby has) between themselves and the competition. PLUS, because guys are on higher milage weeks in general, they are less likely to 'get away' with just substituting miles for XT the way that anorexic competitors do
There's to more nuances to this than most people realize for women's sports- becoming anorexic is essentially becoming male like via fat loss- body fat is estrogenic, when it's lost this is why you lose your period; you don't have the estrogen available to actually be a fully- functioning woman.
I know this sounds pretty grim, but as an NCAA female runner myself, I try to remind myself that 'being the best' at women's cross country does often come at a price that myself and many others are not willing to pay. We shouldn't have to consider eating disorders for success. Sadly, the sport isn't set up for women be competitive in it while healthy.
I know that arguably no one at the top level of their sport is 'healthy', but at all levels of distance running it means unhealthy girls are glorified without anyone really asking 'why' or 'how'.
