Changes

The Spartan works with the various Bluetooth heart rate monitors I tried, including the Polar H7, [[Wahoo TICKR Run]], and Suunto's own heart rate monitor. I found the heart rate monitor that is optionally packaged as with the Spartan worked fine, though I've generally used the Wahoo as I can get the heart rate data on any Ant+ watches I'm also using. The Spartan is unique unusual in supporting the [[Stryd]] footpodnatively, a [[Running Sensors| Running Sensor]] that will transmit "Running Power." It's nice to see these new Running Sensors supported as first-class devices, but sadly Suunto messed up their implementation. The Spartan Ultra will always calibrate a footpod against GPS, so the footpod can never be better than the GPS accuracy. In theory you could always run in indoor mode, or with GPS accuracy set to less than "best", but that's an approach that's likely to go wrong at some point. To compound the problem, the Spartan needs to pair with the Stryd as both a footpod and a power meter, and it can't do both at provides more insight into the same time due to Bluetooth limitations. So, you can get a power estimate than from Stryda Garmin watch, but Stryd's ultrasuch as 30-accurate pace/distance information is inaccessiblesecond average power. The Spartan has an internal accelerometer that will give a reading for [[Cadence]] without a [[Footpod]], and I'd say this is broadly adequate but far from perfect. I tested the Spartan with the Polar Stride Sensor and the Adidas footpod and they transmitted pace and cadence information. However, the auto calibration of a Footpod limits the ability to use these devices.
