About 2.5 hours out with the wife, a mix of cycle path, country paths, the odd country road, a sit down at the riverside locks for a half hour with a sandwich, a tub of mixed fruit and a drink , watch the fish breaking the surface and loads of damsel fly flitting around...and bees carrying small bright green leaves down a hole two feet from where I was sat.. Positively lovely, watch the boaters do their stuff, see a yellow wagtail (ages since I saw one of those) and the ever present red kite floating overhead.
Didn't even break into a sweat.
