🇳🇿WAI2K 50km:
Course Analysis & Race Readiness

A 50km course with 1763m of climbing and 1645m of descent across six climbs and five descents. Nearly a third is downhill, demanding legs that can descend hard and stay intact over the full distance.

CourseRecon scores your own training against the descending and durability demands that define WAI2K 50km — 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 40% 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.

Sustained aerobic output over 50km with 41% flat terrain that rewards steady running.

Pillar Breakdown

Aerobic

With 41% of the course flat or near-flat, sustained aerobic running dictates the overall pace and links the climbs and descents together.

Climbing

100

Six climbs add 1763m, headlined by a 5.6km climb and the biggest single ascent of 453m; steady climbing efficiency matters more than raw power.

Descending

1645m of loss across five descents, including a 6.8km stretch losing 548m at -8.1%, punishes quads and demands controlled, repeatable downhill running.

Durability

The steepest climbs at 26km (15.3%) and 31km (10.2%) arrive after major descending, so legs must resist accumulated damage late in the race.

km 7.4–13.0

The signature climb

A 5.6km climb gaining 453m at 8% is the biggest ascent of the day. Pacing it aerobically preserves legs for the descents and late climbs to come.

km 17.7–24.5

The long descent

A 6.8km descent dropping 548m at -8.1% is the largest loss on course. Controlled downhill running here protects quads that will be tested again after 26km.

km 26.1–33.8

The late double climb

Back-to-back climbs of 330m at 15.3% then 262m at 10.2% arrive on tired legs. This is where durability, not fresh climbing power, decides the outcome.
