The popular Stevenage rides used to be organised as AUK Calendar Events.
If you are considering entering and would like your ride to be validated by AUK, you can still do so by way of a DIY Perm Brevet.
For this you will need to buy a DIY Perm Brevet and submit an entry to your local DIY Organiser, i.e., "Business As Usual" for DIY perms.
For details see
http://www.aukweb.net/diy/DIY South East Riders entering the 200km route are requested to quote DIYSE9560 on the DIY Perm entry form info box. This will be progressed as a GPS DIY BR200 with Mandatory Route. I'll add DIYSE references for the shorter routes as and when riders enter. If you have any queries regarding this, please PM me.
AUKs from other AUK districts should enter through their local DIY Perm Organiser following their normal procedure.
