16°C, confused winds, CK:49 miles

Longer ride today on the Fixed, but less energy from me. Rode for 3 hours with slightly too-thin layers on. the effect is to drain away warmth that takes hours to replenish after getting home. I’m still a little chilly now. The, admittedly light, wind blew from the west today. But looking up at clouds that moved in another direction- is that what wind-shear is?

Have I really have got another 2 days off.
