Enter a goal Pacific Trails 50K finish time and get estimated arrival times at every checkpoint - 51.8 km with around 1,547 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. This is a budget, not a forecast: it assumes the same effort pace from start to finish, and in long races most finishers slow as the race goes on, so expect to be ahead of these times early and behind them late.
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.
