NCN 11 - Fenlands, Cambridge and the Ouse is a 146.2 km road cycling route in East of England with 723 m of climbing, about 8% of it off road, and it splits into about 2 days at a moderate pace.

Saffron Walden to Cambridge is gently rolling farmland on road, then the route drops to the River Cam valley and stays flat for the rest of the way north to King's Lynn. Surfaces are mostly tarmac, with a traffic-free section along the Fen Rivers Way between Barway and Ely as a notable exception. A land access gap on the Cam north of Cambridge forces a detour via Lode before you can rejoin the main line. Beyond Ely the route follows straight drove roads beside drainage channels all the way to Denver lock, then fantastic quiet roads into Downham Market and King's Lynn.
Spring and early autumn suit the fenland sections best, when wind is lighter and the exposed droves are not being swept by a winter easterly. The flat, open terrain gives no shelter from headwinds, and a northerly on the run to King's Lynn will slow you considerably.
Cambridge, Ely, Downham Market and King's Lynn are all on the line, so resupply is regular if uneven along the northern half. The Wildfowl and Wetlands Trust centre at Welney has a cafe and sits directly on the route, useful as a mid-section stop. The Lode detour north of Cambridge is easy to miss; check the turn before you leave Cambridge rather than after you have overshot it.
