Is this the hardest road cycling climb in the world? (+ video)

The Pozza San Glisente in Lombardy is 10.2km long ... and has an average gradient of 18.1 per cent

 

Could Italy’s Pozza San Glisente be the world’s toughest road climb? The people behind Twitter account La Flamme Rouge, who keep track of such things,  certainly think so – they’ve just given it that accolade.

Located in Lombardy, around 40 kilometres due north of Brescia, it’s 10.2 kilometres in length and has an average gradient of 18.1 per cent. Even just thinking about that makes our legs hurt, and that’s before you see the road surface.

There is a Strava segment, too – with the KOM currently standing at 3 hours 2 minutes and 41 seconds – though only one person seems to have attempted it.

The climb it knocked off the top spot? El Picacho de Galipán in Venezuela, which has an average gradient of 14.5 per cent over its 14.3 kilometre length … and as if that weren’t enough, most of its road surface is cobbled.

Given the narrowness of the San Glisente Pozzo climb and the state of the road, not to mention a gradient that would see most of the peloton well outside the time limit, it’s not an ascent that would ever feature in the Giro d’Italia.

But La Flamme Rouge – who are the official race material providers to the Tour of the Alps and other UCI Continental races – say that this climb, the Stentaria in Friuli Venezia Giulia in the north east of the country, could one day figure.

Meanwhile, back to the Pozza San Glisente – if you want a good look at it, sit back and watch this two part video of the descent on a mountain bike.

For comparison, the Alto de l'Angliru in Asturias, Spain, which regularly features in the Vuelta, is generally considered to be one of - if not THE - toughest climb used in any of cycling's three Grand Tours.

It's 12.5 kilometres  long and with an average gradient of  just over 10 per cent, hitting 24 per cent in places.

With the second half of the climb averaging 13 per cent, it's hard work, even if your mum is giving you tips on how to tackle it.

Just been sent this link by a pal. Seeing as I'll be almost driving past it on Saturday I reckon I'll have a look, maybe a walk but I don't think 36/25 will get me very far!

Actually ... lots of non-metalled tracks like that in northern Italy. What's the deal?

Memory playing tricks, maybe it's 10%? Deffo finishes at 20+% though, there's a road sign. Managed to grind up in granny ring but couldn't do it on a road bike with 34/28.

Plenty steep stuff round that way but Wikipedia tells me that the highest point in Lancashire is only 628 metres. No wonder the Yorkies look down on you/them (from their 736m high point).

Calling it a road climb is a bit of a stretch, I'm sure there are plenty of farmer's tracks into the hills that are of similar nature.

There's a road on the moors in the Rochdale area that's about 6.5km and averages  about 15% and kicks up to 20-25% for the last km or so. Did it with a mate on my old mountain bike a couple of years ago and it was grim. At those angles there's no way to start again if you have to foot down and as Carton said, keeping your front wheel from hopping is hard. I don't think I'd have been able to do it on a road bike, even if I had a 32 on the back which I don't!

6.5km at 15% is nearly 1000 metres ascent!

Agree with others, if you've the gears, the legs and the lungs. And probably a bit of technique - as noted above, keeping the front wheel under control can be tricky when it gets really steep.

Not sure I've any of those but a small light has switched on in my brain and it mightn't fade soon...

Sutton Bank and Rosedale Chimney are bad enough, think I'll give that a miss!

On a mountain bike, sure.

Yep. 22-36 should do the trick for most people, really, but the more out back the merrier. That's the beauty of MTB gearing. At over 35% technique comes to play, keeping your front wheel from lifting and your back wheel from slipping becomes tricky, particularly on cobbles.

I wouldn't enjoy going up or down this on a road bike, even on MTB gearing, but I'm sure there are plenty of more skilled riders who'd have a go.
