For those who ride on an indoor trainer Training Peaks Virtual is free this winter. (It is similar to Zwift but not £18 a month..)
You need to download the App, set up a free TP account and have a compatible smart trainer.

Better still you can join your favourite club and ride in the kit. Just select North Norfolk Wheelers from the list of teams and when approved you will be a member.
