How Much Does a 200m Track Slow Down an 800?

If you were in the same shape and had the same race circumstances the difference would be not much.

Less than a second.

Does it depend on the bank? Also interested in answer to the question comparing an 800 indoors banked versus unbanked tracks.

For banked to unbanked, just look at the NCAA leaderboards. They convert 300m to 200m flat times, and 200m banked to 200m flat times. I think it is roughly 1.5s for banked to flat.

For comparison to an outdoor track, I think a banked track is very close to a 400m flat track. Maybe half a second slower at most (if you are in exactly the same shape, of course).

A bit

Having raced a bunch on 400m ovals and indoor 200m flat tracks I can say that there is little difference. Outdoors you have wind and weather. Indoors you have tight turns and little room to wind your way around competitors. If you were time trialing in perfect windless conditions I'd say a second-1.5 seconds faster on the 400m oval.

it also depends on the person..

for me its a big difference because i am 6'5

i ran an 800 indoors once in 1:56, then the next week didnt have a meet so i ran an 800 time trial in practice and ran 1:53

the indoor race was pretty standard with guys pushing and having to go wide to pass so those things do go into effect just as much as the flat 200m track itself.

i'd say unless your indoor 800 is perfect and you pretty much avoid all contact and dont have to pass going out very wide i'd give it about 2 seconds difference.

with all the other things considered, i'd give it about a 3 second difference.

if you're short its not that big of a difference maybe a second.
