In the absence of CTT events many of us will be turning to our turbo trainers to keep up our level of fitness. There are many different services that can help with indoor training. British Cycling are just about to launch a series using the Zwift platform which you may be interested in. You don't have to be a British Cycling member to ride these but you do need a Zwift subscription (typically £12.99 per month).
The events start on Tuesday 24th March and are currently scheduled to run through to mid-May
There are four types of event each week. There are road races on Tuesdays and 10 mile time trials on Thursdays with separate events for women and men. You can ride the events at 12.20 or 19.30 on these days and in different 'performance' categories based on your functional threshhold power.
There are then training workouts on Wednesdays at 12.00 and 19.30 and a Sunday 90 minute endurance ride starting at 10.00am
