Anyone got some light wheels I could hire for a day?

MONSTER!

Ride done. That was absolutely brutal 😵
Never doing that again.

Cracking job. As a regular rider of Edgehill myself I would not fancy 10 times on the bounce, let alone 84.

 

[Ajax Bay]

Well done indeed (lighter wheels or not).
Is there some physiological work that looks at the balance between a shorter climb but a shorter recovery versus longer climb and longer recovery? A simple example is a mile, say @ 8% gives 128m so 70 times. 5mph up ('normal' human not @Marchaugh ) requires 312W on an ascent taking 12 minutes (assumes no following wind on climb), a mile down (<2 minutes) and allow one minute per climb/descent for turnaround, bottle change etc so 4 per hour and 70 reps needed: a long (summer's) day (140 miles / 224km).
Would a long climb (such as Kirkstone) be physiologically better? Of course it will be down to the individual's strengths (recovery speed?), but there must be some known trade-offs.

 

[Twilkes]

There must be a climb somewhere that loops around at the bottom so you get to take momentum into it rather than a standing start each time, that must be good for a few seconds at least.

Everesting is too much for me, but I might try a Scafell Piking one of these days.

Incredible!
Marcus, you should be even prouder of yourself as Everest Base Camp is at 17600 feet... so you've actually ridden 2.5 Everests!

 

[Ajax Bay]

Climb and descent must be the same route so a loop at the bottom precluded, I think. Makes sense to have a layout (both ends) that allows a safe turn remaining upright and riding even when fatiqued > > completely f****d. In Devon, every ride (more or less and not on the same climb) is a Scafell Piking!

The general idea for quick everesting is steeper the better (so as to minimise wind resistance on the ascent). However, there is a balance as the steepest hills tend to be the shortest and you lose a lot of time braking to turn on the descent.
In the UK most of the really quick everests seem to be on 10% for a mile type hills, rather than 6% for three miles type hills. But also nobody everests the 15% for 400m type hills either as the turnaround is the problem

A strong, steady following wind uphill must be an added bonus.

A funicular would be nice too...

You can google the details, but some semi-pro has just done the "Flattest Everest" - in Holland! he used a tiny hill, hundreds of reps, many km ridden.

IIRC he took about twice as long as the current world-record (13h vs 6-ish??)

[matticus]

I might give it a go if loops were allowed - just seems so much more satisfying. In fact, now we're into longer days I might look into doing my own "outlaw" version. (don't hold your breath ... )

Ebike!
I wonder how far you'd get before needing to change batteries.

 

[Ajax Bay]

Yes, I get that the hill needs to be steep enough to minimise loss on ascent due to air drag, yet not too steep to ride down with minimal braking till bottom approach. But from a physiological PoV are you better with a mile at 10% or two miles at 10%? Twice the time to recover versus the physical ability to maintain 3xx W for 20 minutes rather than 10 (say)? One can dodge the question by saying it's an individual thing but there must be some science to offer guidance. And the point about there not being many hills in UK at 10% for more than a mile is a point well made, and a nice straightish descent will narrow the choice even further.
Still rather like the West Dartmoor option where the air is thinner and a westerly gale can offer full value on the straight road exposed slope up towards Merivale from Moorshop. [Talk is cheap.]
