Kunanyi Mountain Run 80 km Ultra: What to Expect and What to Wear on Your Face

You start in the dark. By the time the sun clears the ridge you're already climbing, and from there the mountain throws everything at you in turn: a fern gully, a boulder field, the Organ Pipes overhead, a wide open stretch where the wind has opinions. The Kunanyi Mountain Run 80 km Ultra gives you 18 hours to deal with all of it.

This is a preview for anyone entered, thinking about it, or just curious. We'll cover what the course asks of you, how the light changes over a long day on kunanyi / Mount Wellington, and what we'd think about before putting sunglasses on for it.

Climbing is the whole story

Plenty of ultras describe themselves as hard. This one comes with a number: roughly 4,650 metres of ascent on a mountain that sits right on Hobart's doorstep. The route works through wet ferny gullies, dolerite boulder fields, eucalypt forest and the cliffs of the Organ Pipes, so you'll be hiking steep sections long before your legs would choose to.

The descents deserve respect too. The same 4,650 metres has to come back down, mostly over rocky ground. That's where your quads, your shoes and your sunglasses all find out what they're made of. If you're building out your kit list or wondering what gear long-distance trail runners actually need, trail-tested equipment makes all the difference.

Weather on the mountain

Hobart can be mild at the start while the top of the mountain is colder, windier and wetter. You'll want to read the mandatory gear list on the official event site and pack to it, not to the forecast at the start line. Kunanyi's weather can change quickly, and you could be anywhere on the course when it does.

Light, glare and your eyes

6am in Hobart in March is before sunrise, so your sunglasses will probably start the day in your pack. They'll come out once you're up the first climb and the light starts to build.

After that the light keeps changing. You'll run through dappled shade under the forest canopy, then out onto open sections where the sun and the sky hit you at the same time. UV is stronger the higher you climb, and wet rock, puddles and pale dolerite all throw glare back at you.

That's where UV400 protected lenses earn their place. Polarised lenses also cut the glare off wet rock and standing water, which helps when you're picking footing over a boulder field.

Polarised or not for a trail ultra?

It comes down to what you notice most. If it's glare off wet surfaces, go polarised. If you spend the day checking a GPS watch for navigation and pacing, some screens look dimmer through polarised lenses, so anti-glare lenses without polarisation can be easier to read.

Neither choice is wrong. Tint is mostly a matter of what looks and feels easiest on your eyes, so test it on a long training run before race day.

Why fit matters over 18 hours

For a trail ultra, sunglasses have two jobs: stay on, and stay out of the way. Over an eight to eighteen hour day, a frame that slides or bounces is more than an irritation. Every time you push it back up you break rhythm, and your hands are covered in sweat, sunscreen and trail grit.

Sweat acts like oil. On the steep climbs your head is down, your nose is running with it, and a frame that wasn't shaped for your face has nothing to hold on to. On the descents, every foot strike goes through the frame.

Asian Fit is frame geometry for lower nose bridges and higher cheekbones, and it also suits many European faces. Every Sunday Shades pair also has:

* Asian Fit frame

* FitFlow™

* do-not-bounce and no slide

* UV400 protected lenses

* Unisex design

Two pairs we'd look at

• Surge (polarised). For runners who want glare control on wet rock and open sections. Asian Fit, FitFlow™ and do-not-bounce are standard.

• Volt (TR90 frame, anti-glare lenses, not polarised). For runners who live on their watch. TR90 is a light, flexible frame material.

Both are UV400 protected. Wear whichever you've trained in.

Before race day

Wear them on at least one long training run, including a steep descent. If you can take a hard downhill without reaching for them, they pass. If not, they're not the ones.

On the day, clip them somewhere you can reach without breaking stride. When they get gritty, follow basic sunglass care advice and rinse them with fresh water instead of wiping them dry, because dry grit scratches lenses.

Do I need sunglasses for a trail ultra?

Most people running through changing light benefit from them. Look for UV400 protected lenses and a frame that doesn't bounce on descents.

Are polarised sunglasses good for trail running?

Yes, if glare off wet rock and puddles bothers you. If you check a watch all day, anti-glare lenses without polarisation can be easier to read.
