Pace calculators don't work

Jack Daniels definitely cannot accurately predict times based off anything lower than a 1500. I disagree with the one dude who said the IAAF tables are garbage, I think they can be very helpful in predicting times, obviously we're all better at a specific event and probably don't have the range to run the equivalent time for two events that are totally different. I think the optimal calculator would have to use three data points to calculate your running ability, preferably your fastest event relative to others and the events above and below that event but that's pretty difficult for runners who don't have the ability to go time trial in those specific events.

Anyways, IAAF tables are way more superior to Jack Daniels when it comes to looking at equivalent sprint and distance times. I can run a 61 400 and a 4:56 1600, which is much better reflected in the tables than running a 4:29 compared to that 400 time from Jack Daniels.

You only need 2 data points (but you need to make sure those data points are accurate) for this calculator.

Whomever created that calc needs to work on their algorithm. Lol

My predicted marathon time was 2x my half time plus a few seconds. I wish.

That thing needs a lot of work. Best to use Daniels or McMillan.
