The hardest thing about long bike trips isn't so much leg muscles as having the mental energy to keep going.
The friendly people I meet along the way make more of a difference than they might realise.
Got stuck in an area where people have put up signs saying private road no access. Open Street Maps and Google maps both think it goes.
This afternoon didn't go well. Routing. Unidentified squeaks from my bike. Replacing a worn chain. Tweaking brakes.
Didn't get far today. Friendly warden at the campsite I found. Offered a cup of tea by the folks in the caravan next to me.
I may give up trying to use cycle infrastructure/routes. They are too stressy, time consuming, bumpy, and muddy. (I don't have time to be deprioritised so much)
