Why do men and women race so differently?

I'd say you're looking at a few key reasons, but mostly competitive drive and depth of field.

I'm sure Parker and Katelyn wanted to beat each other just as much as Nico and Graham did. The more accurate explanation, I think, is the women have 2 super stars who are outliers from the rest of the field.

There's just way more parity right now in the mens scene than the womens. And depth of "top" runners. It wasn't that long ago that Connor Mantz won the spring '21 nationals by over 20 seconds and had over 40 seconds on 8th place.

Maybe also men tend to be more confident in their kicks? See how I asked this as a question rather than a statement? Cause I'm a woman.

Easily depth. Every conference/league I've ever been in or observed the top women completely dominate the rest even if they're less experienced. Easier for talent to float to the top with less competition. Men's side has a ton of mid and upper mid level talent guys who are willing to train their brains out.

I think it has to do with the distribution of the women's abilities. For men, the distribution curve is a lot taller and tighter. Meanwhile, women the curve is a lot wider.

Take a look at the top 100 men in last year's 5000 track list. The top men are separated by 30 seconds. The top women are separated by 1 minute.

One theory---Anatomically, most men distance runners are pretty similar. Women though, the outliers with more narrow hips seems to have an advantage. The body differences in women cause bigger margins of spread across the field.

This further manifests in xc because the very top women are only truly racing maybe 5-10 other people. So more aggressive tactics aren't as risky. Men, because there are fewer outliers, end up racing lets say 20-30 people, making aggressive tactics a higher risk scenario.

I know right? The sexes are basically interchangeable

Great post.

The depth of men’s athletics is way more than women’s athletics. This is at every level, we’ve got women pushing 14 flat in a 5k and yet a 15 flat runner has a chance to make a global final. Meanwhile the difference between best in the world and not making the final is 20 seconds or less. Because there’s a lack of depth, women can easily separate themselves and guarantee a high finish. Men are too close together and if you take the race out hard you just end up as the pacer for a dozen guys and get kicked down at the end

Could race distance play into it at all?

I'd argue that since men race for a longer period of time, especially in XC, the gap should be even bigger than the women's if depth was the same.

It could be that women have greater variability in ability, amongst themselves, versus men as a group. Perhaps due to hormones, or something else, who knows. Men love the idea that they are so competitive that their close finishes (vs. women's races) must be due to their natural aggressiveness!

1) The women, especially Valby, ran hard all the way;

2) The men hung out in a group, all of them waiting for the finish.

Summing up, none of the men had the guts to push the pace all the way on their own.

These gender takes are so random. Competitors are self interested and go with the strategy they think most likely to succeed.

I think that, at all levels of competition, men's performance tends to follow a normal distribution, while the distribution of women's performances tends to be right-skewed (ie, lots of performances around a point that is much further from the fast outliers).

Take a typical high school race for example. My experience is that most boys' races in competitive areas have 1 or 2 guys who can run in the mid to low 15s, a few more in the high 15s to low 16s, then the majority of the field comes through in 16:30-17:30. It's incredibly rare for a boy to run under 14:30 or so on an XC course.

On the girls' side (in the same area), a lot of meets are won with a time in the mid to high 18s (although it's reasonably common to see sub-18). Girls tend to trickle in until 19:30 or so, then most of the field is around 20:30-21:30. The big difference, though, is that lots of girls in the country run sub-17 on a legit xc course every year.

Basically, "normal fast" for boys is about 30-60 sec slower than national elite. For girls, "normal fast" is more like 2 mins slower. "Normal fast" is a term I invented for the kids who end up making up the bulk of the rosters on mid-tier D1 schools.

If you take a look at a graph of the distribution of testosterone levels in men and women, it looks strikingly similar to this distribution of performances, and I don't think it's a coincidence.

Wow. Kiptoo would have run 22:50 that day if his shorts hadn't malfunctioned... he was so distressed about it, running with one arm down starting as early as 2km in with his nuts hanging out. Poor guy. Definitely cost him the CR and impacted performance. Great run, that's how you race XC.

I think this is something that could be explained more clearly with some research and analysis. I see it in the difference between men’s and women’s 800 runners. There are exceptions but for the most part men’s 800 runners are too big to be effective 5000 or even 1500 runners. There are women’s 800 specialists but there are plenty who can run 800-10000 because women with narrow hips and very light builds can be effective at any of those distances, even against more muscular 800 running women. Different “things” make men and women good and for men it’s pretty much universally the same and there aren’t really outliers who excel because they’re different, they’re just “more good” at what the others are doing. Women like Valby look completely different from the middle pack D1 women’s runner. Physically she is different. For men, it would be hard to tell a 13:10 man from a 14:10 man just by looking at them run a lap. I don’t know the exact reasons for this but it’s something I’ve always observed and it makes comparing the sexes really difficult.

Women actually go for it from the start in XC.

Men tend to form a "p#ssy-pack" -- running unambitiously in a group until someone finally pushes the pace near the finish.

This is why men leave a lot on the course, while women are actually spent and collapsing after races. Hang out in a finishing area and see the difference.
