Decide if it's better to extend it on the flat roads to the east, or the rolling scenic roads around Oakham prior to hitting Peterborough. What's the target milage, anyway, captain?
Check for routing gremlins. I'll re-ride the Leeds-Peterborough section at the end of the month. Also think there must be a better option around Potters Bar.
Take a look for audaxes which exit London via Potters Bar and compare it to the current route?
At the moment I've got a small section on a cyclepath next to the A1. It's fine, and if I remember right it links up a nice section. But possibly there's a better way.
You didn't take a step backwards when the rest of us did.
So, team two... core route could look like this (has the advantage of a supported control at 160km/Peterborough).
