Help with a swmming math problem

Mathematically, how do you work out 'three quarter pace"? Let's say (for the sake of easy calculations) your best time for an event is 1 minute. In practice, you want to go three quarter pace. So a 100% effort will result in a time of 60 seconds. A 75% effort should result in a longer time. My rudimentary maths tells me I should divide 100 by 75 and multiply the result by 60. That works out to 80 seconds, which is a minute and 20 seconds. Why does that sound much slower than what I would normally envisage three quarter pace to be? Or is my maths completely messed up?

  • the problem with your math is each 25 would take 1/3 of your 100's time so if you expand that out to 100 isn't it 4 x 1/3 = 4/3 or 133 1/3% which is 33% more time wise if you go 1:00 in the 100 free wouldn't 75% effort or 25% slower be 1:15 The obvious corollary here is that it is impossible for any two people to agree on what 75% effort actually means. I don't use % efforts in my workouts, but if I did, I'd use the definition I provided, because it is so simple, it can be applied even when the maths-challengeds are too tireds to calculates diddlys/squats.
