I was desperate to do this as its one of very few audax rides local to me. The organiser never received my cheque though, as a consequence I didn't receive a route sheet or any kind of confirmation and I missed out. Was it a good turnout? Apparently there's another Herts ride on the 20th but I'll be at the Manchester derby! I was really disappointed, lumpy as it is the Hertfordshire countryside makes for pretty nice riding. I've been doing my own route up to Bishop's Stortford and back round anyway, a little over 100km. Sorry to hear about your post-LEL low, like you say its pretty natural. After LEJoG I didn't enjoy riding for weeks!
