TIFU going out for a long walk in capris and forgot to sunscreen my legs

Obligatory not today, however recent. I decided that since for once it was an unseasonably cool day meaning around high 60s till 70s,

I was going to go out and take a nice walk. now, when I get going I really get going. So, I sunscreen to my face and arms even got my back and my neck where my t-shirt would pull away got my arms and what not. Put on a hat full brim even and I was wearing t-shirt, capris, socks and sneakers. Packed everything I thought I needed like multiple large bottles of water snacks and a camera. One thing I didn’t pack was the bottle of sunscreen.

No this is a beautiful cool day however there were no clouds and no cloud cover. Started around 10:00 in the morning heading west for almost three hours. That’s right, the sun was behind me the whole way. Round 12:30 or 1:00, I turned back and headed east for 3 hours. So in total around 6 hours of walking with the Sun behind me or directly above me the whole way. And I have fair skin and red hair.

So I’m kind of thrown to sunburn. Also, even though it was cool, there was no cloud cover and no shade. When I got home, back to my legs look like a cherry tomato. Kind of my legs didn’t look like much. Still slightly pink though, and now, a week later, I have a dark brown band around my lower leg stretching from mid calf to ankles and the rest of my legs are white.

TLDR: am prone to sunburn. Walked for 6 hours with the sun directly behind me having not sunscreened my legs. Got a stupid looking tan band.
