How women runners debunked myths about the sport and made running their own

3. Well, For One Thing, Most Of The Myths Are Plain Stupid

It's obvious that running is not bad for anybody health.
I do quibble with the "women aren't slower" myth though.
1 second in the hundred meters is a lot! It's about 34 feet at the finish line. And 25 seconds in the mile is also huge. It's nearly half a lap.
In the Marathon, the delta in the world records is nearly 12 minutes. That's 5% of the time, which would be about 1⅓ miles.
Now, a lot of that has to do with height & length. There a few 5'2" world class make runners, but many women are in the 5'2" to 5'4" range. There are few world class women runners at 6'3". But, lot's of men.
If you have the musculature and twitchiness to be fast, having longer legs is an advantage.
So, women are slower than men, but it's not about testosterone, it's more likely about height.
Other than that, the rest of the article makes obvious sense.
