What are you asking us?
Does anyone want to ride a 600 which consists of 6 loops based on Oakham? (No! too easy to abandon)
Can I ride an Audax route which uses the same bits of road repeatedly? (No, just no)
Is there any interest in running a series of short rides from Oakham? (Possibly, but I suspect you need a greater variation in the routes. We're just about to start the Marple series, a long-standing series of well attended events in the Peak District every Wednesday in August).
