I cannot remove best efforts for all segments from 400m to 10mi. They are all based on a run which had bad GPS data. I tried flagging the run but I am not sure if it is flagged currently. For example, it says my PB for 400m to 2mi is 3 seconds! I am not that quick !
The raw data is from Suunto watch and is accurate in terms of distance and time despite bad GPS data
