HYROX Tracker: ROXZONE

Parent Pace: Stroller GAP
A beta running data field that shows stroller-adjusted pace: your pace corrected for the slope like grade-adjusted pace and then for pushing a running stroller, so hard hills with a stroller show what the effort is really worth.

Walker
A free data field for walking activities: step count, distance, pace and calorie burn in a compact format made for casual walks rather than running.

Race Screen
A race data field that corrects the difference between GPS distance and the real course: press lap at a course marker to round the distance and adjust your pace. Predicts your finish time.
