I think the singular is "butty" and plural "butties", at least that's how I've always spelt it. Regardless, canny whack a good bacon/egg/sausage or chip butty (chips being chipped potatoes bigger than french fries)

Rode hard in the winds last night, left knee felt tweaked this morning so had to change gear and spin like mad at times this morning. Made my ride a bit slower, but felt much better nursing the knee rather than force myself to fight through.

Bit warmer this morning.
