Using Jeff half marathon program,
Warmup, intervals and run are normally bunched up an included in gpx data and connect summary.
For "magic mile" the gps track only starts in the run itself and it is not possible to get the gps track of the full route.
None if this is correct or useful but I'd prefer having the full gos track all the time.
To improve,
make all warmup more clearly optional or dynamic,
have a clear lap cue before timed distances (jaff always miss this)
And present the timed distances only as an option to all, now averages like speed include pointless warmup and rest intervals.
