Ten dimensions
DimensionDiagonale des FousHardrock 100
Distance & format
5

About 180 km across Réunion with a 66-hour cutoff. Longer and stranger than a standard 100 miler.

4

A 102-mile San Juan loop with a 48-hour cutoff. Long, not a stage race, not a road 100.

Vertical
5

On the order of 10,200 m of climb on volcanic terrain. The profile is relentless.

5

Official 33,441 ft of climb; thirteen crossings above 12,000 ft. The vert is the event.

Technicality
5

Steps, roots, mud, night, and technical volcanic trail. This is not a runnable Alps path.

4

4WD, trail, and true cross-country. Snow and loose rock are normal in July.

Climate
5

Tropical heat, rain, humidity, and cold on the high points. Climate is a full dimension here.

4

Monsoon lightning, lingering snow, and hard freezes at night. Summer is a rumor.

Altitude
3

High points around 2,400–2,500 m. Real, not the main weapon. Heat and terrain do more.

5

Average elevation over 11,000 ft; Handies Peak at 14,048 ft. This is the altitude 100.

Logistics
5

A long-haul island: flights, French administration, night start in Saint-Pierre. The travel is part of Demand.

4

Silverton is remote. Crewing is a mountain skill. Lottery is the real gate, not the fee.

Prestige & field
4

A French-world icon with a cult international field. Not UTMB-famous; more serious than that implies.

5

Small field, outsize myth. Getting in is a career; the start list still means something.

Organization
4

Grand Raid is a large, practiced event with public course notes. Confidence is medium-high.

5

Community-owned since 1992, stable course culture, kiss-the-rock finish. Deep public record.

Value
4

The flight is the tax. You are paying for an island that does not exist in Colorado.

4

Fee is not UTMB-scale. You pay in years of lottery tickets and a week in the San Juans.

Adventure & scenery
5

UNESCO volcanic interior, cirques, rain forest, ridgelines. There is no substitute course.

5

Telluride, Ouray, Sherman, Handies. If you fly for mountains, this is the flight.
