I have a regular route of about 2.8km which my app/device have logged in a number of occasions. On my last run the distance recorded as 2.44km despite the route showing as previous on the map. Had it recorded properly this would have been a PB but being short the recorded splits were longer. Any ideas why this may have happened? Also, my app is not showing heart rate on the route but when I check the data in the heart rate section it is there.
