Discussion: Entering PACE in Training Log entries

Help ! Something seems to have gone wrong with training log entries when I enter the pace of training. I used to enter a pace eg 800 or was it 8.00 and it would calculate the distance from my time. Am I doing something wrong or has the form broken?

this was broken, but should be working again now.

Thanks - it's working fine again.

On that note i have a question. When entering a training session and providing the distance, mighty ap will provide a pace calculation which is very simple p=d/t (pace is distance over time). When also inputing climb, it will provide a second calculation, in italics. Initially i though it would just use pithagoras and calculate the extended distance based on a climb, but... if you put 10k distance in 30 min with 200m climb:
Pace=3min/k
Alt Pace=2.44min/k.
But sqrt(10000^2+300^2)=10004.5 which if you use p=d/t will give you a pace of 2:59.92, in other words, bugger all difference.

What else is involved in the calculation that has such a generous pace once you involve climb?

The fact that it's harder to run 200m uphill than to add on 4.5 m to your 10k. I think 5*climb is added to the flat distance? So 10k with 200m climb would be 11k.

I think it's based on a simple calculation that 10m climb = 50m on the flat, which is a rough rule of thumb when considering climb. It can get far more complex - there are several 'rules' when considering time estimation of a certain route, which add a certain distance on dependent on gradient up (and down) etc

so
p=d/t
AltP=(d+5c)/t
That result comes pretty close 30/11=2:43.6, which is rounded up to 2:44.

Thats pretty close, thanks. i'll leave the "climb weighing factor" reasoning to the sport physiologists out there.

The factor used to be 10. This thread (and possibly several other sources) got it changed to 5.
