🇪🇸Transgrancanaria 23 km:
Course Analysis & Race Readiness

A 23 km course packing 1458 m of gain and 1096 m of loss into three climbs and four descents. One sustained 10.5 km climb of 1106 m sets up 37% of the route spent going down.

CourseRecon scores your own training against the descending and durability demands that define Transgrancanaria 23 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 43% 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.

Pillar Breakdown

Aerobic

The 10.5 km, 1106 m climb from km 2.3 to 12.7 demands prolonged aerobic output, but at 23 km the overall aerobic load is contained.

Climbing

With 1458 m of total gain concentrated in three climbs and 15.1% of the route very steep, this rewards strong, efficient uphill power.

Descending

Descending is the dominant demand: 1096 m of loss over 37% of the course, with 18.8% very steep and a 485 m drop across 4 km, punishing technique and quad control.

Durability

After a 1106 m ascent to the 1718 m high point, legs must handle sustained pounding descents, testing the ability to hold form late.

km 2.3–12.7

The Long Climb

A single 10.5 km ascent gaining 1106 m at 10.6% average takes you from 685 m to near the high point. Managing this effort defines how much you have left for the descents.

km 14.8–18.8

The Big Descent

A 4 km drop losing 485 m at -12.2% comes after the summit, one of the steepest sustained sections. With 18.8% of the course very steep downhill, this is where descending skill and quad durability pay off.
