Good ride today on the ZHR Audax ... Was sand bagging with the C riders, and had some great banter. Frustrated with continued ANT+ dropouts which mean I had to exit zwift and rejoin ... then it would work ... before dropping again ... finally worked it out when I noticed that unlike other times the Vectors had no signal, but other sensors did ... Penny dropped batteries flat in the vectors, paired with the Bkool, caught the group (again), then restarted trainer, as it was giving no resistance and reporting silly watts ... no issues for rest of ride ... Decided to do Box Hill as an after party, as I didn't get enough yesterday, I wanted to make the metric century, and had a dropout at the top just after the stage finished ... I'd earned that descent!!
