🇮🇹Tor des Géants:
Course Analysis & Race Readiness

340km with 23,000m of climbing and matching descent across 34 climbs. A relentless mountain circuit where accumulated fatigue and endless steep terrain, up and down, decide everything.

CourseRecon scores your own training against the descending and durability demands that define Tor des Géants — the sample analysis below shows exactly how.

What This Race Demands

Four things this course asks of your body

Every course weights the four pillars of mountain-ultra fitness differently. Descending carries 52% of the scoring weight on this course — the terrain makes that the deciding factor.

Weighting shows where readiness is won or lost at this distance — not whether you need each pillar. An aerobic base is a given for a race this long, so it carries little deciding weight even though it's essential — the gaps open on the climbs, descents and the back half.

AerobicSustained engine

Foundational

Days of continuous forward motion demanding a deep, sustainable engine over 340km.

ClimbingVertical power

20%

34 climbs and 23,000m of ascent, including a 1,698m single climb and grades near 25%.

DescendingEccentric / braking

52%

23,001m of descent over 33 downhills, some to 2,100m loss and a 20.8km drop.

Multi-day effort where repeated 3,233m altitude exposure and endless verticality erode the legs.

Pillar Breakdown

Aerobic

With 340km covered over multiple days, the aerobic system must sustain low-intensity output for an extraordinary duration without collapse.

Climbing

Thirty-four climbs totaling 23,000m demand efficient, repeatable uphill technique, especially where 26.8% of terrain sits at very steep climb grades and the biggest ascent gains 1,698m.

Descending

With 23,001m of loss and 25.9% of terrain at very steep descent grades, the course punishes quads relentlessly — one descent drops 2,100m over 20.8km.

Durability

The defining test: accumulated damage from repeated climbs and descents over 340km, plus altitude to 3,233m, means holding form deep into the effort matters most.

km 63–74

Descent-to-climb whiplash

A 1,112m plunge at -24.8% into km 67 flips immediately into a 1,258m climb at 22.4%, hammering quads then lungs back-to-back.

Biggest descent

The 2,100m drop

A single descent shedding 2,100m over 20.8km demands controlled braking that would wreck untrained legs early in a race measured in days.

Cumulative load

23,000m up, 23,001m down

Across 340km the total vertical is the true crux; managing effort and damage over 34 climbs and 33 descents determines who finishes strong.
