The wording of the motion passed at the 11/15 AGM included:
"Under mandatory routing riders follow the route set by the event organiser*, subject only to dealing with any eventualities that might occur such as road closures or other factors which might render sections of the route inappropriate. Riders deviating from the route will be expected to rejoin the route at the earliest available opportunity and/or make general progress in line with the route in accordance with the published guidance for the event. So for example, for a regular Permanent with AAA points riders might be expected to follow the set route exactly, whereas for DIY Permanents some minor variation might be allowed subject to the rider demonstrably progressing in accordance with the registered route."
*for a DIY, that's the route the rider entered for.
