Everesting World Record Attempt

[Vetplant]

So after Paul's reply, I started wondering whether some basic VAM - W/kg calculations would add to his suggestion that steeper climbs are more effective...

 

Using the VAM = fn( W/kg and % gradient) calculation which you can find on google (this calculation is an application of some v basic Newtonian mechanics together with a gradient correction factor seemingly attributed to Dr Ferrari):

 

The relationship between VAM and relative power output is expressed as follows:

 

Relative power (Watts/kg) = VAM (metres/hour) / (Gradient factor x 100)

 

This gradient factor ranges between 2.6 for a gradient of 6% and 3.1 for a gradient of 11%. To work out the gradient factor take 2 + (% grade/10).

 

I took this relationship and speculated using a fixed W/kg = 4.0 (as an example), as to what VAM you could achieve for differing gradients. See graph below.

And it does appear to suggest that you can achieve higher VAM on steeper gradient climbs, for a fixed W/kg. A caveat is I don't know what restrictions are applicable to the gradient correction factor.

That makes sense for the up, but only addresses the climbing rate aspect. It doesn't tak into account the turn around at the top and bottom and the descent.

In an ideal world you would prefer as hard a gradient that you can climb that goes the 8848m vertically in a single trip, but that doesn't exist.

 

Alternatively one would think that you would want a climb as long as possible to reduce the amount of turn-arounds and also maximise your descent distance traveling at maximum speed. You want to spend as much time as possible climbing and reduce the amount of time not-climbing.

 

That is my understanding though of what is "ideal". I may be wrong. 

 

Would still be awesome to watch this attempt though, I will make sure I do a ride that day and go past there to see the attempt

You laugh, Delano had to do an extra rep than Kevin and I as his garmin was under recording... Or ours were over recording.

Would the strava feature "with friends who recorded?" not be able to override devices that under recorded?

Not sure how many of you have tried Everesting.

 

I had a go at it a few weeks ago and to spice things up we decided to do it on a dikwiel off-road.

 

I threw in the towel after 5k climbing not due to any physical discomfort but purely the mental drain of doing endless repeats on the same hill.

 

I am not sure whether I can do it on a longer hill and thus less repeats but am damn sure that doing 100+ repeats on the same bump is not for me (to complete we had to do 98)

 

PS of the five starters, one completed and went on to do HRS in 29 hours. Utter madness if you ask me

Once you get into a rhythm its not actually all that physically taxing (depending on the hill) but it is 100% a mental game.  If I do it again I'll take along an audio book, music or something else to distract me.  I had nothing except for the south easter blowing in my ears.  We had to do 81 repeats of our hill, and near the end I was falling asleep on the downhill from boredom (literally - I was on the left hand side of the road and 'woke up' riding into the drain on the right.  Kinda dodgy.)  We had a couple of people arrive at different times, and I found that incredibly helpful.  It takes your mind off what you're doing and gives your brain a bit of stimulation for a while.

Did it in the neighborhood.

Helps a lot.  You get guys doing gardening.  Shopping.  Walking dogs.  Joggers.  Drunks coming back home at 3am.  Security patrol. Newspaper delivery. 

 

Helps with the monotonous up and down.

We would have to be friends on strava then

I tried 3 times and did it on last attempt, 4400 5760 then 8900. 

 

Its mental but also gearing. 

[CharlesZ]

here you guys talk about doing everisting. I thought of doing it again but to think of it now. Not the hell again (for the time being)

 

Well guy by the name of Alex actually going to do an awesome climb. Kowyns pass, think it might get dangerous with the trucks etc using it but will be an awesome climb

[Grease_Monkey]

A friend did this Everest on a longer climb a few weeks back on his mtb - the climb was around 900m per shot that he did 10 times.

 

Absolute madness if you ask me.

 

[dave303e]

A cool one would be to back to back everesting. 

 

Do the skyrun climb to the mast on foot and then back it up cycling up Jouberts to the mast.

 

900m climbing/10 reps for each

This is what I'd do if (when) I do it again.  Longer route FTW.

What climb was this? not many constant 900m climbs in SA.

He must be a rather big boy or be crazy strong to avg 221w for 15 hours

He recently moved to Hong Kong - so he did it there. Not sure of the climb's name.

 

Yup, he is a big guy, and an absolute beast when it comes to power - did that on a Camber too!

this theory makes sense, but in practice i see one big issue.

 

for looooooong endurance events, you want to be a diesel engine ticking over, not a stop start interval session. That, for me at least, points to such a short climb being a good idea until you try and do it quickly. just way too much red line. try keep that up for 8 hours and you will blow an O-ring along the way

 

(once again, more than happy to be proven wrong)

Well I guess that if you're trying to do any hill quickly enough to Everest in 8+ hours, it'll be quick! Part of the challenge, I guess. But if choosing a steeper hill keeps your required W/kg down, for the required VAM, then you'll be further from your red line? But a fair point about the stop-start bit.

My gr1 maffs, that's like 21ish km per climb... what would the gradient be for such a climb?
