Can this ride be done as a permanent?
if you can manage an extra 50km, I run a 200km Gospel Pass AAA Permanent from Cheltenham, which of course can be started at any control such as. Cinderford, Monmouth, Hay-on-Wye.
Also, you can always try my Calendar on 23 May, where the air temp should mean no icing; of course I cannot promise no rain, cos that's Wales (and a touch of England). I did a recce yesterday to prove some of the roads on the English side, West of Hoarwithy; it's a Cracker! And AAA too.
