Phew, was just about hanging in there when the “Battery Low” banner want across the screen. Damn, charger lead had fallen out of the transformer.
Got it plugged in and thanks to Zilog and Scaredy made in back in, then on the next hill I felt pain in my left calf, so eased off and cruised around cursing.
Been having this issue for a while, is ok mostly but if I really push it comes on, feels like either cramp or the muscle pulling. After the first time I rested for a couple of weeks and thought that was it but it re-occurs from time to time.
Thanks to Weeksy for organising and to others for the help, see you on the next one.
