The 150h00 cutoff sits at about Index 334. The typical winning time, 66h06, sits at about Index 795. A model estimate, not an official ITRA or UTMB figure.
From a result you already have
What the predictor gives on Tor des Géants for a few common reference results.
| Road marathon | 3h00 → 97h57 | 3h30 → 114h17 | 4h00 → 130h36 | 4h30 → 146h56 |
|---|---|---|---|---|
| 50 km trail, 2,000 m D+ | 5h30 → 82h23 | 6h30 → 97h23 | 7h30 → 112h17 | 8h30 → 127h12 |
Road marathons use the tool's rougher power-law fallback.

Predict your Tor des Géants finish time from a reference race result, scaled for the course's 336.5 km and 26,182 m of climbing. The 150-hour cutoff is generous by hundred-miler standards, but the course is more than twice the length of a 100-miler and the prediction assumes you keep moving - your sleep is added on top.
Predicting a Tor des Géants finish time
Tor des Géants is 336.5km with 26,182m of elevation gain and a 150-hour limit, starting and finishing in Courmayeur. Winning times sit around 66 hours - Victor Richard set the course record of 66:08:22 in 2025 - while the cutoff allows more than six days, so the spread between the front and the back of the field is wider here than on any hundred-miler.
Why a scaled prediction understates this race. The model extrapolates from a reference result using distance and km-effort, and that extrapolation assumes continuous movement. Over 336km nobody moves continuously: every finisher sleeps, and total sleep across the week ranges from a couple of hours at the front to more than twenty in the middle of the field. Take the predicted time as your moving time and add your own sleep plan on top of it.
Extrapolating this far is uncertain. A 100-mile reference result is less than half the distance of Tor des Géants, and Riegel-style scaling grows less reliable the further you push it. The prediction is most useful as a sanity check against the 150-hour limit and as an input to your checkpoint splits, not as a target to chase.
The cutoff is not the binding constraint early on. The overall limit is generous, but the intermediate barriers are not uniformly so: La Thuile at 19km closes just five and a half hours into the race. Once you have a predicted finish time, put it through the Tor des Géants Aid Station Planner to see which barriers your pace actually clears.
