When doing a side-by-side comparison of activities it would be good to see the temperature (and humidity?) for each activity.
Thanks.
When using the Compare option, there is a temperature from a weather station for both activities.
Max temperature recorded by a watch is another case, but you're right that it's still null on activities summary which is used for export. You can write a script like here: Export CSV from Garmin Connect miss avg temperature and fail to export max temperature.
