Two days on NCN 41 from Rugby down to Bristol.

Train to Rugby, coffee stop in Warwick at Pastelaria Portuguesa, fish and chips in Stratford at Barnaby's, (eaten on the river bank with a classical guitarist busking), coffee in the Old Post Office in Beckford (they were closing, but stayed open to make us coffee nonetheless), and to The Bell at Tewkesbury for dinner, beers and a massive breakfast, comfortable beds, good showers and bike storage in their courtyard.  Took the westerly braid rather than the Cheltenham route, up to the cathedral at Gloucester, then down the canals and lanes towards Avonmouth.  Coffee and cakes at Ley Bistro in Frampton on Severn, sunning ourselves on the green.  Long stop to allow a herd of friesians to go past, up the Avon Gorge and into Bristol.  Trains back to London.

Great route, apart from a slightly grungy stretch through Avonmouth.  Quite a lot of unpaved railway and canal track, so 32mm touring tyres probably the minimum - we had a couple of punctures but tyres were past their sell-by date in hindsight.  Quiet lanes, lovely views over the gently rolling scenery, succession of nice towns on day one, day two more rural between Gloucester and Avonmouth.  Easy going over two days at just over 70 miles per day as not hilly at all.  Could be tricky going NE to SW if windy as prevailing wind will funnel up the Bristol Channel, but we were lucky with the weather.
