Garmin race predictor (feddit.nl)

Does anyone here have experience comparing the times of the Garmin race predictor for different events? I know that usually it slightly overestimates me or that I haven't been able to run the time yet, but I'm curious how the estimations compare for different distances.

Or otherwise in general, what are your thoughts on sports-watch/app generated predicted race times?

I've found the estimated times to be almost laughably bad, and worse the longer the distance.

Right now, mine estimates:

5k 17:22
10k 36:02
Half 1:19:38
Marathon 2:46:25

My 5k PB is 18:48, 10k is 38:55, and I've only done one marathon at 3:14:24. But right now? My goal is to do a sub-18 5k by the end of the year, and that is far from a sure thing. I've no hope of doing it today, and I doubt I could even complete a marathon (at least in any remotely reasonable time) today.

So no, I don't put a lot of stock in it.
