Hi

 last year we went to Howstein on the same day as the Audax ride, so we passed riders and used the same route back to Otley?  That date this year is  18 july

 27 Jun there may be a few riders going through hollingworth at the end of a 600K, and also others on a 200.  Imagine Blackstone after 500+ kms! 

wetherby-Filey is early this year,  5th June and registration is now open,  route will slightly change at start but not much ( miss out roundabout near services)

 how about 21st march for 50 in 3 reliability ride?
