Because she's not you?
I hate running in leggings, partly because I have short legs and large thighs and it is a real struggle to find anything that fits. I have finally found a pair that aren't too bad, but they're certainly not be first choice. The crucial feature for me was ankle zips, so I can pull them off if I get too hot (I always wear shorts underneath).
> Professional athletes warm up gently, and keep the leggings on until the last minute to keep everything warm. A US cycling Team manager used to fine his cyclists if he ever cought them cycling with uncovered knees, unless it was above 70F.
Then I suggest you go down to our lido in a couple of months and chastise all the people who will be swimming in 60F water. It rarely gets to 70.
If I wore leggings at 50F, never mind mind 70, I'd be chafed to hell from all the sweat.
> My dad, despite (and probably because of) my nagging insisted on wearing shorts in all weathers when walking, even in a blizzard on Kinder. He needed new knees at age 65, and the surgeon said his shorts habit will have contributed.
What's walking in a blizzard got to do with running in what was presumably not a blizzard?
> I never wear shorts when running, I don't see the point, my Ronnies are the default kit, in any weather. They don't hinder or chafe, I even sometimes wear knee warmers as well (as well as the willie warmer).

Because we're not you.
