Step 1: Build hill Step 2: Profit

[Profpointy]

Halve (or even eliminate entirely) the material costs by digging a huge hole. Pile the excavated material next to the hole, then ride from the bottom of the hole to to top of the pile. No need for imported material. You can thank me later.

Edit: Damn, beaten to it by Drago.

You can do better than that. Dig the hole twice as deep, sell all the mud for the £30 a ton Mike above quoted and you can fund the entire project.

I'm thinking that a worked-out mine might be better. With a bit of imagination, you could have both up and down tracks and double your profit.

You could build a track straight up the side. None of gentle incline stuff.

[QUOTE 4966401, member: 9609"]so this hill is going to be 400 foot high with a 40% slope. So I'm thinking some sort of cone shape hill ?
so the base will be 2000' diameter ?
lets give the earth 8 stone per cubic foot
(not really sure how to calc the volume of a cone)(500^2*3.142*400)?
but I reckon you will need 15.7 million tonne
that would be 100 bulk tippers a day delivering for 15 years.[/QUOTE]
Cone volume is pi r^2h/3
So volume is 500^2*3.142*400/3, which is 1/3 of your answer. Which means truck movements for only 5 years instead.
(But what's this tonne business? Surely if you're working stuff out in cubic feet and stone, your answer should be in ton(s))

Yep, the gradients on my scheme were chosen to suit my listless and pathetic athletic abilities.

My management consultancy is provided without regard to sporting prowess. The fee remains the same.

Give your local council a ring and see if you can hire one of these;

My plan B was to use a an out use quarry. Such as the abondoned slate quarry in Llanberis near Mt Snowdon. Snowdonia is a peak cycling and tourist area and cheaper than Hertfordshire. All it needs is some grading and tarmac.

 

[Beebo]

If you built it they will come.

Or not. Probably.

The cone of shame

Giant hamster wheel is the answer.
If you pedal fast enough you could go vertical. None of this pansy 40% stuff.
Install a row of them, to better serve the obvious clamour for their use.

Dry ski slopes work because it is a long way to get to any actual snow.

You can have that one for free.

Just ring Trump, and offer to build the hill on top of Kim Jong-un, if he'll kindly provide the body, and the funds. The hill will be built in no time.

I've actually ridden down that on a mtn bike.
