Pretty enough village but the only access other than via the A14 is from Grafham, making it a dead end for cyclists.

Careful in the winter - this was pretty unrideable. Mainly grassy byway. Imagine it's super fun when dry!

Structure dates back to the 13th century. However, various parts of the structure that we see today pre date this and there was a previous church here; and a church of some importance as well with Stow Longa being confirmed a prebend by Pope Eugene III in 1146.

Nice approach from the south down an avenue of trees. Ford is definitely not rideable on road tyres except maybe after a long dry spell - use the footbridge. Road to the north is very broken in stretches.

Nice village, very nice gastro pub The Mermaid. But no means for cyclists to get over the A14 from here.

Don't follow Komoot strictly (like I did) 😉 - obey the signs from farmer/landowner & NCN signs - small mistakes can be forgiven, I suppose, when we new to the area.

The cycle path along the top of the dam is wide and flat and gives great views across the reservoir. Reach it from the Visitor Centre at the northern end although access at the southern end is trickier as you have to squeeze through a narrow gap next to a locked gate by the main road.
