Even pacing is the baseline; Pacing tilts it toward a negative split or a fade, and the window is the ± band you set. Cutoff / buffer shows the aid-station cutoff and your projected buffer (green) or shortfall (red). Carry to next is what to leave each stop with to reach the next one — the Start row is what to carry off the start line, and every leg includes your reserve buffer so you never run to empty. A 🌙 marks checkpoints you’ll reach after dark (set a start time + sunset/sunrise).
