🇪🇸Transgrancanaria 47 km:
Course Analysis & Race Readiness

A 46 km descent-dominated course dropping 2420 m against 1405 m of climbing. Fifty-six percent of the route runs downhill, headlined by an 11.3 km descent losing 801 m. Braking legs decide this race.

CourseRecon scores your own training against the descending and durability demands that define Transgrancanaria 47 km — 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 53% 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
Sustained effort over 46 km, but climbing volume of 1405 m is modest relative to descent load.
ClimbingVertical power
14%
Six climbs totaling 1405 m, with one crux climb gaining 473 m at 11.7% over 4 km.
DescendingEccentric / braking
53%
Dominant demand: 2420 m of loss across five descents, including an 801 m and a 473 m plunge.
DurabilityLate-race resilience
32%
Repeated hard descending stresses legs late; braking damage accumulates across 12.3% of very-steep downhill.

Pillar Breakdown
Aerobic
75
With only 1405 m of gain over 46 km, sustained aerobic output matters but is secondary to withstanding downhill load.
Climbing
100
Six climbs and 1405 m of gain concentrate into short, steep efforts, notably the 473 m crux climb at 11.7% grade between km 7.6 and 11.7.
Descending
75
Descending is the defining capacity: 2420 m of loss over five descents, with 12.3% very-steep and a single 11.3 km descent losing 801 m.
Durability
88
The relentless net loss of 2420 m batters quads and connective tissue, so leg resilience through the late 801 m descent determines finishing pace.
km 24.6–32.1
The 801 m plunge
The longest descent drops 801 m over 7.5 km at -10.7%, the single most punishing braking effort and a decisive quad test in the back half.
km 7.6–11.7
The 473 m climb
The only major climb gains 473 m over roughly 4 km at 11.7%, the sharpest sustained uphill and a spot to manage effort before the descents.
km 13.8–17.7
Steep early descent
Immediately after the crux climb, the course sheds 473 m over 3.9 km at -12.1%, front-loading descent damage before the biggest drop arrives.
