After a 64km fast ride yesterday evening (avg 34km/h), i got a personal record message while saving the data. These are common these days because i upgraded from 2.60 firmware to 2.70 on my Edge 810 and this upgrade wiped out all previous personal records. So nothing new i thought when the message appeared and i didn't pay attention but after uploading the data to Garmin Connect, my personal record showed that i rode 40km with an avg speed of 38,4km or 1 hour and 2 mins and 30 secs.
I find this 38.4km/h quite high, certainly after looking at the speed graph so i wanted to retrieve the 40km part of that 64km ride where the avg speed of 38.4km/h was measured and i can't seem to do that. Is this even possible...?
