These are for experienced and self-sufficient cyclists. They may be ridden at any time, but entry should be made well in advance to the organiser. Although the routesheets are each written for a particular start location, you can ask to start at any other control along the route. For a DIY event you write your own routesheet.( DIY details, and online purchase of cards here.)
Entry forms and other details are available via the Audax UK Permanent events list [external link].
Note that the routesheets may be updated only occasionally.
Entry fee is the same for all the routes at £3 a go (send fee and entry form by post and include 2 SAEs for routesheet and return of card).
Alternatively, you can pay for an entry online for £4 here. Send an entry form by email and download a routesheet. For online entries postage is included in the fee.
More information is available on the Audax UK website.
