My race prediction is not accurate, I understand that it is an estimate and that each person can get closer or further from that estimate... I have always had as a reference that in a 10k race I can do 1'30" faster than what the watch gave me (I always train with the HR band Pro plus)... and I do not expect it to be perfect, since I understand that is impossible, but I would like it to be more reliable, since in recent times due to my lack of training my prediction has gone down and this Sunday I ran a 10km race giving me a prediction of 42'50" with which I expected in the best of cases around 41'... the fact is that I finished with a time of 39'29"... that is, 3 minutes lower than the prediction... so I no longer know to what extent I can trust the race prediction... I do not understand how a platform like Garmin with so many metrics available doesn't make them more reliable...
