How Garmin calculates best time (1km, 5, 10, half marathon)?

Hi,

I'm wondering how Garmin calculates records. For example if I run half marathon (21,1km) and if I manage to run 25km - how Garmin will calculate my hm (half marathon) record? Will it take best part from my 25km (for example starting from second km up to 23,1th km)?

Or will it take from very first km up to 21,1 and whatever I run further it won't matter?

Same with 1, 5, 10km. If I run 20km with different pace; will Garmin take best continius 10km (from total 20km) or from very first kilometer?

I do hope you know what I mean.

Mike

I think the question was not about race prediction, but rather about personal records.

Yes. That's how it works, with a peculiar caveat for activities that…

It is looking at your VO2Max (which compares pace to HR as a % of HRMax), and looking at that as a basis of predictions. It also looks at how long your recent runs have been. So if you focussing on your 5K time with no longer runs, your predicted 5K times might be good, but your predicted marathon times may blow out.

So it can build it's predictions, even on the basis of sub-maximal efforts. It is not looking at your best paces.

Yes. That's how it works, with a peculiar caveat for activities that are just barely longer than the personal record distance.

Thanks for the answer.

I indeed meant my personal record. Thx
