1200m altitude gain, obviously. D’oh.

Four hours?

depends on how steep the road is

About 4x longer than if you rode it.

let’s assume a gradient of 1:10

that’s 12km to walk.

assuming an average of 3kph.

4 hours.

Is there a moving conveyor belt?

Depends on fitness too surely. Took me about four hours to get up Ben Lomond with my bike, which is 950m of ascent I think – lots of it’s more tricky than a fire road though. I’m pretty unfit also.

😆

assuming an average of 3kph.

I’d think an average of about 5kph would me more realistic, although I guess it depends on fitness and weight of the bike.

5kph would make it about 2 and a half hours anyway.

Well if you are pushing the whole way, roughly the same as walking, so use Naismith’s rule which is pretty accurate. 4km per hour plus 1 minute for every 10m of height gain. Can’t believe there will be no riding at all in a 1200m height gain. Obviously not in the UK

chainless DH. sick rad dude.

What’s the terrain like, how steep, how heavy is the bike, how fit are you?

i once walked from 600m in brides le bain, up to 1300m to la tania.
i was pushing mine and my son’s bike, after we arrived for the last ski lift, and it had left.

Ride it? Just fireroad…

sounds like a how long is a piece of string situation

Naismiths Rule should give you the answer.

4km per hour ie 1000m every 15 minutes PLUS TWO MINUTES per contour line crossed.

Don’t forget that Naismith was carrying a pack at the time and not pushing a dirty great big bouncy bike up the hill.

All calculations will be meaningless if the 1200m is on Crib Goch style terrain where you are picking your way around rocks and clitter. (LOL)

Didnt realise contours were universally spaced on all maps? 😉

Unrideable fire road?

I’d think an average of about 5kph would me more realistic, although I guess it depends on fitness and weight of the bike.

If you’re the sort of person who walks up hills, or on the sort of bike that has no low gears, either way I reckon you’re unlikely to keep up a typical flat ground walking pace up a blooming great hill like that.

For what it’s worth, I did a 10 km 1000m uphill with a bunch of downhillers in nz, and I think it took them close to two hours even riding some of the less steep bits.

Contours were 10m on all OS maps for ages

They’ve startd doing 5m on some now though..

Naismiths rule is 5 km/h plus 30 mins for 300m

thats 1 min for 10m

I just looked it up in Langmuir…

People used to pushing DH bikes all day will push up it more quickly than novices can ride up it on XC bikes.

lol ROTFL e.t.c

burma road in scotland,
took me longer to bike than it did the people walk, made it though!

I have yet to be passed by one. Either I am not a novice or that is wrong.
I can believe you can walk up quicker happened to me on Skiddaw by one fit walker- rode most after the zig zags

Is this a scientifically proven fact with mbr control tyres??

Answer is 140 minutes by the way – I found last week the rule of thumb is 100 metres every 10 minutes, in general; plus a bit for food/water breaks. Works every time.

With a bike that is pretty good going. Must have been aggressive 😉

Answer is 140 minutes

was it for a bet? I can’t imagine much else making me push a bike I could be riding for over 2 hours…

I suspect its the goods that reward the push that make it worth it.

Naismiths is imperial you revisionist dogs.

3 mph plus half an hour a thousand feet.

2 hours’ climbing for 2 hours’ descent = a fair deal (though it says little for my speed on the way down)!

Thinking about it, I believe it was a bit more than 2 hrs going up actually…nice walk though
