Garmin but not Forerunner

[OakLeaf]

The Forerunners also have the "Back to Start" function.

If your main concern is getting lost, then you kinda need to shell out for the 705, because that's the only one with street maps. I'm loving mine! - but they're not cheap.

If you had a Forerunner 201/301, and the reception is what you disliked about it, the newer 205/305 has the same high-sensitivity receiver as the Edge models, and supposedly the antenna is positioned better as well.

The only thing the Edge 305 has that the Forerunner doesn't is the barometric altimeter and the larger display. (And I don't think you can buy the Forerunner bundled with a cadence sensor, you have to buy it separately.)

On the other side, the Forerunner has a wrist strap and multi-sport functionality, where if you want to run with an Edge, you have to carry or pocket it, and all your data will download into your cycling folder in Training Center (although you can move it manually or of course use other software). There's also an optional footpod for the Forerunner 305.
