Here is the rough route. I will post a detailed one in due course.
We will get train to Newmarket (1h30, via Cambridge).
Ride Icknield Way, to Thetford.
Ride Peddars Way, to Swaffham or thereabouts.
Ride bridleways to Kings Lynn, where I know a good chippie.
Train back to London from Kings Lynn.
I expect each day to be around 60km of easy riding. Almost pancake flat. Singlespeed welcome.
Cross bikes, hybrids even, would be fine. I'll be on a SS rigid MTB.
We will wild camp somewhere half way along. Make a fire and some food and have a nice evening.
Plentiful resupply points along the way for everyone.
If you have been camping once before, you have enough experience to come along.
Join us for a fun ride :)
