You can choose to show gradient adjusted pace or not and control if GAP or normal pace is used for “time in zones”.
You need to setup pace zones in /settings for Run to get the new stuff. For existing runs you can use the “Update Activities” button in /settings to update them or choose “Update Zones” on the “Actions” menu for the activity. This might take a while if many activities require elevation correction.
Elevation correction uses GPS coordinates and topographical maps to determine elevation (and hence gradient used to calculate gradient adjusted pace). The default setting is “Auto” which uses elevation correction for devices lacking a barometric altimeter. Elevation from devices with only GPS is usually very inaccurate. Data from Strava is not corrected because Strava provides data with very good elevation correction.
Note that the topographic maps are not universal so elevation correction might fail. In particular areas more than 60 degrees North (Scandinavia, Alaska, Iceland etc.) are not covered. I will be adding more maps soon.
The activity settings dialog (click “Actions” under the activity timeline chart) controls elevation correction for individual activities:
Intervals.icu maintains a database of devices with barometric altimeters for the “Auto” setting. If your device is not listed with Yes/No or the information is incorrect please click it and supply the correct information.
The “time in zones” popup for an activity will now use pace zones:
If the activity also has power and/or heart rate then the “Priority” option decides which is used. The default is taken from the “Time in zones” setting for the sport in /settings.
If elevation correction has been enabled for an activity then you can add the “Fixed Alt” chart to see the corrected profile:
Next up: Fix whatever bugs come out of this and get “pace vs time” done (like power duration curve).
