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.
