Your next ultra
Your history comes with you.
Your record
NavRun reads your history from Strava or your watch and lays out every week to race day around your usual week. Had a short week? Say so and it rebuilds.
The clock
NavRun does the cutoff arithmetic before the start. You see when you reach each aid station, and how much room you have on its clock. Drop bags planned.
The night
Your crew and your pacer get one link and no app. They see your race day and talk into it, and their voice notes reach you out on the trail.
