How much "extra" did Nijel & Bosse run on Bends ?

not again.

Other than two steps from Bosse on turn 1, neither of them even touched lane 2 on a bend until the end of turn 3. Bosse was on the rail by turn 2 and took a couple steps wide on the homestretch. Nijel was on the King's shoulder through turn 3 before touching lane 2 at the end. So at most 2 meters for him and for Bosse, none at all.

Does that 2 meters even make any difference, I doubt it. Running on the rail has its disadvantages because it's a tighter turn, and Amos was keying off Rudisha and probably getting a draft too. Take Rudisha out of the picture and put Amos on the rail, I don't think he goes any faster. Maybe even Bosse beats him. As he would have in any event had he not been too surprised to be in the hunt at 700m.

The wavy line Bosse took from the break to lane 1 is negligible extra distance.

rubbish

go look at whole race properly & last 3 bends

if you think nijel ran only 2m extra on last bend, then you have no clue about maths

You are using the formula 2*pi*r for the arc length right?

Another classic Ventolin troll thread. I'll be really disappointed with LetsRun if this makes it more than a page.

dumb question

it reduces simply to :

pi * how wide in lane

if you run wide in lane 1 for any bend, say 0.75m wide in a 1.22m lane which route-1 is 0.3m from kerb, you run extra of

2.36m

analyse last 3 bends & apply above formula

how do I watch it properly? Are there special glasses or something?

Even if Amos had been on the line of running in lane 2, it would have been only 3.5 extra meters. He was well inside lane 1 nearly the whole way, about 20cm from lane 2. Freeze frame around 1:46 a few times if you don't believe it. 10cm is the width of a human foot, and there is visible space (5+ cm) between each of Amos's feet and the lane 2 line, which itself is 5cm wide.

That's at least 40/112 of the way from the lane 2 LOR to the lane 1 LOR, for an extra distance of at most about 72*3.5/112 = 2.25m. About 2 meters.

yeah, but it is still the formula you are using. You are ignoring that space-time is curved! Get a clue about

geometry on manifolds!

no

fool

there are 3 relevant bends

He was well inside lane 1 nearly the whole way, about 20cm from lane 2

now apply that to 1st 2 bends

& then also to last bend where he is visibly in lane 2 before bend ends

Freeze frame around 1:46 a few times if you don't believe it. 10cm is the width of a human foot, and there is visible space (5+ cm) between each of Amos's feet and the lane 2 line, which itself is 5cm wide

then use your brain & factor in his centre of mass woud be ~ 15 - 20cm lateral to inner foot

for an extra distance of at most about 72*3.5/112 = 2.25m. About 2 meters

we want precision

that number is 2.25m

for what ???

can't you comprehend

pi * how wide in lane from 30cm in

???

Correct. I don't always agree with your comments, but this is exactly the case.

Quick enough to beat Jim Ryun.

Now go back to your cave and cry big aspie tears until you finally learn to stfu.

some wild running

ideally, you want to run tight in lane 1 from gun-to-tape

what "extra" distance did these guys run ?

Seriously, it's just an 800. The extra distance is insignificant.

"It's just an 800" and "extra distance is insignificant" seem kind of contradictory, wouldn't you say

I mean what difference does a few extra meters in the 100 meter dash make...

You can't get precision. You're eyeballing distance by estimating arc-segment lengths travelled by estimating lane spacing based on, among other things, average foot width on a video replay with multiple cuts. It's false precision. Bad Wigins rounded appropriately.

Engineer out.

What do you mean "extra"?

Do you mean extra?

Troll. You are not on first names basis with Mr. Amos.

you can get damn precise estimate if you have analysed enough vids

utter drivel

foot width ???

is sasquatch running in the race ???

on a video replay with multiple cuts

learn fool

you look for violent changes in body position relative to other runners

if none, you know the trajectory remains basically unaltered before/after cut away

It's false precision

no

it's very good precision if you analyse properly

Bad Wigins rounded appropriately

no

he didn't

Engineer out

you are no engineer
