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?

  • I don't think you can just plugg in numbers and calculate effort in % of times. (it wasn't as confusing in my head as it is in written form :) if I swim (what I feel to be) 80% or 90% 100 free. maybe my 80% is 1:20 and my 90% is 1:10 but my 100% race time is 1:00.9 Using just math I should be 90% at 1:07, 80% at 1:16 so maybe the 100-90% works better than 90-80%, but after that it seems hard to measure effort and time in linear %, there should be some kind of sloping factor. I hold 1:20 for most of my distance swimming meaning (roughly 76% of my 100 time), but that would make my fastest 400 time 4:04 and it's only 4:41 and my practice times around 5:10-5:20. does that mean I swim my 400 times at 90% even though I feel like I am only swimming 80%??
