She’s on her way back

This post always makes me a little emotional. Every year.

Will be up and out on the water meadows at first light in the morning.

Yep. Go to work in the dark. Work inside all day. Go home in the dark.
Past couple of weeks I’ve been going for a 15min walk at lunchtime but it’s probably not enough to make a difference.

I've managed to get out for a lunchtime walk occasionally. I don't suppose it makes any significant difference to your vit D intake, but I was surprised at just how much difference it makes mentally, particularly on a sunny day. Genuinely felt refreshed and more with-it in the afternoon.
