Honest question here, what's the advantage of having a garmin doofler over a mobile running strava?
Not used Strava, so can't compare but reason we opted for Garmin Edge (apart from it having all the desired features) was we knew it would sync seemlessly with the garmin heart monitor we already had. It may have changed but there were difficulties using garmin heart monitor with Strava, I think there was an adaptor you could get but unreliable and the support was not continued, something like that? Plus we already owned the Garmin Forerunner 610 running/cycling watch and foot pod, so were already familiar with the interface. The Foreunner still useful for running but never use the cycling option since getting dedicated Edge cycle computer. It's just not as good, the touch screen is really awkward even for slim fingers. But the Edge is excellent.
