TfL sponsors cycle training and maintenance programmes in all boroughs, see: https://tfl.gov.uk/modes/cycling/cycling-in-london/cycle-skills?cid=cycle-skills
For Southwark link is to training company Cycle Confident at http://www.cycleconfident.com/sponsors/southwark/
3 levels of training, 1:1, free, are offered
Basic cycle skills; Urban cycle skills; Advanced cycle skills
This last one is interesting Says it will: “Perfect your cycling techniques with a free one-to-one session from a fully qualified trainer. Improve your performance when dealing with complex junctions, heavy traffic or cycling at night and receive assurance that you are cycling efficiently and effectively.”
I had not realized anything other than basic training was offered free. Such a course might be excellent for some of the Bike Train riders and some of the Healthy Riders.
There are also subsidised cycle maintenance classes. In Southwark these are also run by Cycle Confident at their Kennington base, cost is £18 for a 4-4.5 hour Saturday class. Basic and advanced sessions, approx. monthly.
It would be very interesting to hear comments from anyone who has tried any of the training or has gone on a maintenance course.
