Predicting longer distance times from shorter.

I swam in a non-santioned meet Sunday (short course meters). I did a 25 *** in 17.63, and in the 50 a 39.71. Given my 25 time, should my 50 time be better? The 25 has almost no aerobic demand. I always heard multiply by 2.2, which would equate to 38.786. Both races had decent starts and I thought I did a pretty good turn on the 50. I guess the real question I am asking is if this likely has to do with not being conditioned enough to swim a faster 50. Clarification: These were separate races...the 25 time was NOT a split for the 50.

  • According to Ed Nessel, (Cullen Jones' coach): for FR, with very good conditioning and proper splitting, the best possible 100 should be about 2*(best possible 50) + 3.5s. That assumes the first 50 is your best 50 time + 1s and the second 50 is 1.5s slower than the first. If your 50 is 31.0, the best 100 you could expect with good conditioning and good splitting is 1:05.5. For a 200, double the 100 and add 11s. These work quite well for fr, bk and br. fly typically has more fade.
