| cledlie: | 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? |

| ken: | this was broken, but should be working again now. |

| cledlie: | Thanks - it's working fine again. |

| jotaigna: | 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? |

| bshields: | 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. |

| distracted: | 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

| jotaigna: | 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. |

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