Recorded on the Edge 820 The spike in temperature in Wrightwood must have been due to the Edge having sat in direct sunlight while stopped. It will absorb a lot of heat if in direct sunlight, particularly without any air movement. I also recorded it on my iPhone app, but have deleted that entry after copying over the below notes. The elevation gain reported by the iPhone app was more stingy, only showing 13,530'. Distance measured between the iPhone app and the Garmin differ. As mapped, this ride was a minimum of 119.1 miles, and from the GPS track shown here I have removed the tails from before we started and with my stop after finishing at 7-Eleven, etc. Both devices were using GPS instead of the speed/cadence sensor. At mile 26.0 on the Edge (approaching Newcomb's), the iPhone app shows 26.3 mi. Leaving Newcomb's, mile 27.0 on the Garmin was 27.4 on the app, easily attributable to the app recording my walking around at Newcomb's while the Edge was stationary (on the bike).
