Hi all, might be a bit of a noob question, but is time to exhaustion and time to recovery automatically evaluated by the app or is this something that needs to be manually input it cheers

If you mean the Garmin Connect IQ data field, click More under description here for instructions –
Time to Exhaustion - Xert | Garmin Connect IQ

If you mean the data field on EBC you can tap the field to configure it once an activity is started.

Sorry yes for the garmin IQ app. Cheers for that so seems I have to input manually. Will see if I can work it out
