All 16 Kodiak 100M checkpoints pre-loaded. Enter your goal finish time to get estimated arrival times at every aid station.
Full Kodiak by UTMB - 100 Mile course data: aid stations, cutoffs, course profile
Enter a goal Kodiak 100M finish time and get estimated arrival times at every checkpoint - 162 km with around 4,850 m of climbing, with crew and drop-bag points flagged.
Starting estimate based on the cutoff, not on published finish times. Replace it with your own goal.
Turns every arrival into a clock time and every cutoff into a margin.
Terrain changes how the goal time is shared between segments, not the total. One surface everywhere cancels out.

Highlighted rows use a pace heuristic (>12 min/km / >19 min/mi) - likely hiking by speed, not grade. The grade-based power-hike cue is ≥15% (see GAP and Incline tools). Times are distributed proportionally by km-effort.
Leave by is the latest you can start the next segment and still make every cutoff ahead of you at this pace - often set by a station further on, not this one. It does not yet subtract the time you spend stopped, so treat it as the optimistic edge.
Cutoff buffers are estimates from your goal time and published barriers. Courses and barriers change - verify against the official race guide.
