The 14h00 cutoff sits at about Index 330. The typical winning time, 5h23, sits at about Index 866. At the 2026 edition, the median of the 1,478 finishers took 10h34, about Index 488. A model estimate, not an official ITRA or UTMB figure.

From a result you already have

What the predictor gives on PDA 55K for a few common reference results.

PDA 55K: predicted finish from reference results
Road marathon	3h00 → 9h16	3h30 → 10h48	4h00 → 12h21	4h30 → 13h54
50 km trail, 2,000 m D+	5h30 → 7h38	6h30 → 9h01	7h30 → 10h24	8h30 → 11h47

Road marathons use the tool's rougher power-law fallback.

To prepare each checkpoint, use the PDA 55K aid station planner.
