I just went for a cycle ride, and measured it using the cyclemeter app. Interesting that the watch activity counter didn't count this as exercise in the green ring. I realise I didn't use the onboard workout app, and perhaps I should have, but I'd have expected that cyclemeter and the watch would share exercise data via HealthKit. I guess we're all still learning the ins and outs of the watch. I just want my darn badge!!! LOL!
