4.88k

some drama in the philly runners message board that i didn't really run a 24:21 5k this past weekend:

Using Sheila's assumed course length of 390 feet short, the course was 16014.1944 feet instead of 16404.1944 feet (5280 feet per mile, 5K=3.106855 miles). Therefore, racers ran 97.6225593% of a 5K (short course divided by 5K), a 4.881127965 K.

To extrapolate your time for a 5K, multiply your time by 1.024353395 (5K / short course). First, convert your time into seconds, multiply by above, then convert back.

24:56 would be my extrapolated time.
