Scorecard
CCC vs OCC vs TDS scorecard
Chamonix week is four races if you count the icon 174. These three are the rest. OCC is the short mountain day. CCC is the 100K where worth outruns demand. TDS is the harder long line, demand 5, not an icon. Same town. Not the same ticket.
OCC for the short Chamonix mountain day, CCC for the 100K with real Worth, TDS when you want the harder long line without the UTMB icon.
No blended index. Low Worth is the take.

Worth
5 out of 5
Worth the flight + fee
CCC is the Mont Blanc 100K that is allowed to be worth more than it demands. Demand is 4: Courmayeur to Champex to Chamonix, about 108 kilometers and 6,200 meters of climb, late August, the same cols and storms as the flagship, a long alpine day that becomes a night if you are honest about your pace. It is not 5 because it is not 174 kilometers and because the technicality is TMB-family trail, not a scramble. It is not a 3 because this is still a mountain 100K in three countries, not a lakeside loop with a World Series sticker.
OCC
Orsières to Chamonix · 50K
Demand
3 out of 5
How much it asks
Worth
4 out of 5
Worth the flight + fee
OCC is the short mountain day on UTMB week, and the score is allowed to say that without sneering. Demand is 3: about 60 kilometers and 3,500 meters of climb from Orsières through Champex toward Chamonix, late August, TMB-family trail, a field that is deep because the town is deep. It is not 4 or 5 because it is not a 100K and because the technicality is a famous hiking trail. It is not a 2 because 3,500 meters of alpine climbing is still a mountain race, and because Chamonix in August is not a local 50K.

Worth the flight + fee
TDS is the long race in Chamonix week that people who actually like mountains talk about when the 174 is the one people photograph. Demand is 5: Sur les Traces des Ducs de Savoie, on the order of 145 kilometers and 9,100 meters of climb, a wilder and more technical line than the TMB loop, a Monday start, nights, storms, a cutoff that does not care that you are not in the flagship. It is not a 4 because denser vert on a meaner trail is the top of the demand scale even if the distance is shorter than UTMB. Technicality is a 4. Vertical is a 5. That pairing is the card.
| Dimension | CCC | OCC | TDS |
|---|---|---|---|
Distance & format | 4 108 km, Courmayeur to Chamonix. A mountain 100K, not a shortened UTMB and not a 50K. | 3 About 60 km. A mountain 50K-plus, not a 100K and not a VK. | 5 About 145 km, harder line than the TMB loop. A long alpine push, not a 100K. |
Vertical | 4 About 6,100 m of climb. Dense alpine climbing without the 174 km tax. | 3 About 3,500 m of climb. Enough to be alpine, not a 174 km tax. | 5 On the order of 9,100 m. Denser and meaner than UTMB's 10,000 m over more distance. |
Technicality | 3 TMB-family trail, crowded on race week. Alpine, often runnable, occasionally steep. | 3 TMB-family trail. Alpine, crowded, often runnable. | 4 Wilder than the TMB: steeper, more technical, less of a hiking-highway. Technicality 4. |
Climate | 4 Late August on the massif: storms, cold cols, heat in the valley. Same weather as the 174. | 3 Late August. Shorter day, same massif weather in compressed form. | 4 Late August, start earlier in the week. Storms, night, heat. Same massif, less crowd on course. |
Altitude | 3 Grand Col Ferret and the usual TMB high points. Alpine, not Hardrock-thin. | 3 Cols on the Swiss-French side of the TMB. Alpine, not a 14er. | 3 Alpine cols, not Colorado 14ers. Repeated, not once. |
Logistics | 4 Stones, Index, lottery, Chamonix week. Easier than UTMB only in distance. | 3 Stones and Chamonix week, but a shorter day. Easier than CCC, still a destination weekend. | 5 Stones, Index, first-come registration, then a Monday start while the town is already a circus. |
Prestige & field | 4 A deep field in the same town as the final. Not the icon; still a destination start list. | 3 A deep 50K-plus field in the same town as the final. Not an icon. | 4 The connoisseur long race of UTMB week. Deep, not the global-final spotlight. |
Organization | 4 The same professional machine as UTMB. Competent, commercial, high confidence. | 4 UTMB machine. Competent, commercial. | 4 Same machine as UTMB. Competent, commercial. |
Value | 3 Circuit tax for a 100K on the massif. Worth 5 is the place, not the stones. | 3 Circuit tax for a short mountain day. Worth 4 is the place. | 3 Circuit tax for the harder line. Worth 4: the mountains, minus the icon identity. |
Adventure & scenery | 5 Italy to France under Mont Blanc. This is why worth outruns demand. | 5 Same massif, shorter line. The scenery is why people fly for 60 km. | 5 The massif off the TMB highway. Scenery 5, with fewer selfie poles on the col. |
