Changes

* '''What's my cadence? '''[[Cadence]]''' '''is one of the most critical and often overlooked aspects of running. If you get your Cadence right, many other things naturally fall into place. The Ambit3 supports [[Cadence]] via a [[Footpod]] or it can estimate Cadence from its internal accelerometer, though I've found the internal accelerometer can be out quite a bit. Sadly it has no alerts for when your Cadence is too low.

For ultramarathon running the high end Ambit2 has the battery life for shorter ultras, but for runners that expect to be moving during the [[Second Dawn]], you'll have to compromise GPS accuracy for the Ambit2 to go the distance. See [[Best Running Watch#Watches for Ultrarunning| Watches for Ultrarunning]] for more details.

=Which Version?=

The Ambit2 comes in four versions with different functionality. I think the "R" has the best value for money, but depending on your usage you may want to pay for a more expensive version. If you're a cyclist, the "S" might be worthwhile, though I won't comment further as I focus purely on running usage. If you're an ultrarunner, then I think the "Ambit2" version could be well worth it. (The Sapphire is only worthwhile if you're hard on your gear and want the damage resistance.)
