600 record question

[BillCarr]

an honest question for all you track nerds:

is there a reasonable conversion out there for 600 yards to 600 meters ? Our club's 600y record is 1:13ish, but someone recently ran a 1:22 600m, which seems intrinsically faster. However, just using the 1.0936 factor, the 1:13 is WAY faster. Any thoughts ?

(for what its worth, the 1:13 is from 1976 at Dartmouth's flat track, and the 1:22 was run on the new BU smokin fast track)

Since 600 meters is only 52 meters longer than 600 yards the 1:13 is a much better time.

Re: 600 record question

The conversion is difficult because those 60-odd yards could be covered in widely different amounts of time. If the 400 guy is running it, he's tieing up and taking more time; if the 800 guy is running it, he may be in full kick mode. The simplest method is to subtract a second from the time (to account for the 'overcoming inertia' part of the start) and then apply the math conversion of 600 y vs. m. But then you also have to take into account for the fact that 600m is just enough farther than 600y that you can't run them at the same speed. I (just me maybe) think that the 1500/mile conversion is easier because you are more aerobic there, while the 600 is anaerobic. So have I totally confused the issue?

Oh, and add the second back in.

600y=548.64m
600m=656.5y
Standard conversion for y to m is 1.0936, so 1:13y = 79.8m = 1:19.8
Conversion from m to y is .9942, so 1:22m = 81.5y =1:21.5
I think that is correct, but need the actual .1's.

all well and true, but as someone else quite aptly pointed out, the 600 m is enough longer than the 600 y that you can't just use simple math.. 56 yards more, after already running 600 of them .

Re: 600 record question

I use factor of 1.1043 - so Reynolds' 1:06.86 equals 1:13.84 converted (1:13.12 pace). Gray's 1:12.81 would equal 1:05.94 for 600y (1:06.58 pace). What would be nice is an official conversion chart for all types of tracks, for what it's worth. All 500y--600m records are hard to compare, with all those different tracks. Some amazing times from way back.. Ben Eastman's 600y (68.8),1934, was 1:40.53 800 pace! And Mel Sheppard's 1:10.8 in '09 was 1:43.45 pace.
