My 5K and 10K really accurate. I ran completely on feel and got within seconds of the predicted time on both sessions. I do wear my watch day an night so it has a lot of resting data as well. Also I was wearing the watch since the beginning of my running journey.
My FR955 said this morning that I could run 10k in 49:52. I ran todays race in 45:42. Now it predicts 48:47….

The more you run various distances, the more accurate the estimates.
