GAP is grade-adjusted pace, the flat-equivalent pace for the effort. On an even-effort plan it stays roughly constant while your actual target pace rises on climbs and falls on descents. Switch to “By terrain” to pace the course by its climbs and descents. The highlighted rows are aid stations: edit your rest with the ± steppers and every arrival, departure and the 30:00 of total stopped time folds into the elapsed clock. The cutoff badge shows your buffer against the official cutoff at arrival. The ☀/☾ is the wall-clock hour from the official 11:30 PM start, so you know when to expect a headlamp.
