Garmin Edge 25

I do this with a Garmin

I do this with a Garmin Forerunner 910XT (which I originally had) as it only has breadcrumbs for navigation, but connects to the cadence, speed and HRM sensors. I save and upload its journeys. I wanted the forerunner’s running and swimming functions as I do triathlons.

I bought a separate Touring as it was the cheapest half-decent Garmin navigator (and I got fed up of trying to make smartphone maps etc work), so when I need navigation, I run them side-by-side, and don’t save/upload the Touring’s journeys. Clogs up the handlebars a bit but they’re small enough to manage.

Edit: incidentally, anyone else having to ‘view source’ to actually read the comments on some of these posts?
