A clockwise route to Ely heading out via Cottenham and Coveney and returning via Wicken and the Lodes Way. There are great views of Ely cathedral from the higher ground at Coveney.
This route has several extended off-road sections - the Cam towpath out of Cambridge, the riverside path out of Ely and the Lodes Way. All these sections have reasonable surfaces when dry but get puddles after heavy rain. There is a footbridge with steep steps on the Lodes Way that is tricky with large or heavy bikes. Use the alternative route that returns via Upware to avoid this footbridge.
