well, you can make a stab at it & get some sort of an estimate

in return, people will have to do some homework & find all the major banked & unbanked tracks in the world

now, rather than waffling on about angle of bank, let's just assume the maximum height of lane 6 above the flat ( if you do find the angle of the bank, relative to the inner lane ( NOT along the lane ), the height is just:

sine angle * (1.22 * 5)

( each lane is 1.22m( it is outdoors !) & assuming that lane 1 ( 20cm from edge is race distance measure ) is 0m elevation ))

interestingly, on the Big Guy'z site, he said the angle is upto 18 degrees, which gives ~ 1.9m)

anyhows, we'll just assume it ranges from 1 - 2m

i tried just a simple energy consideration method to get an estimate ( don't know how good it is, but it's a start )

well, when a guy runs on a bank ( assuming starting at it's peak, halfway round it, which i suggested is the case in another post ), he starts at the highest point & during the course of the race, he will drop from that ht. to zero level, acquiring PE which will increase his KE compared to the flat

now PE = mgh

& KE = 0.5mv^2

(we can ignore mass from now one as it will cancel out )

the equation you get is

0.5V^2 = (gh) + (0.5v^2)

where V is actual speed in banked race, assuming lane 6 & v is theoretical speed on unbanked track

i won't bore you with the workings, but it boils down to,

for a 200m race:

t = (40,000 T) / ( 40,000 - (2ghT))

where t is theoretical time on unbanked track in lane 6 & T is actual time run on the banked track
