Climb 8,849 m of cumulative ascent with a pack on — sea level to the summit.
Enrolling starts the count at zero.
Rucks you have already logged stay in your history but do not count here — the point is the walking you do from now on. There is no deadline and nothing expires underneath you.
Counts ascent recorded on the activity, so device-recorded rucks contribute and flat manual entries mostly do not.
Checkpoints are the real camp altitudes on the south side, read as cumulative ascent rather than height above sea level. Needs recorded ascent, so flat manual entries do not contribute.
Rucks imported from Strava never count toward a challenge. Progress and the badges it earns are shown on public profiles, and Strava’s API terms allow their data to be shown only to the person it belongs to — so the same rule that keeps those rucks off the keeps them out of here.
