I am sitting waiting for a neck x-ray wearing my customary shorts looking at my tan lines.
My daughter has a perfect tan. She works at it. She goes to the beach at every opportunity and, she buys minimalist clothing for the occasion. No tan lines. She can wear whatever she likes without fear of a tan line showing.
I, on the other hand, am a cyclist. The only time I am in the sun is on my bike wearing bibs and jersey. I am tanned on my face, hands, forearms and on the legs from just above the knees to the ankles. And, I am dark. The mark of many hours on the saddle. However, the rest of my body is white. Really white. You don’t want to see me in a bathing suit.
A bikers tan is a badge of honour. A right of passage. Something you must have if you want to be taken seriously on the road.

I don’t really tan but I have some darker patches where I’ve (unfortunately) burned.
Have you read the rules? – the velominati – tan lines are supposed to stay crisp and perfect. I still Kitesurf and do stand up paddleboarding so mine gets mixed up but I respect the lines as those in the know – know.
Not yet but it looks interesting. I’ll try to pick up a copy.
Thanks.

My favourite is rule no 5
Been thinking about this lately myself, as my daughters tease me at the beach. LOL. Nice post.
