I use the Virtual Partner setting when running my longer training run and hope to end up a few minutes ahead of the target virtual partner over 20 or 30km. The 935 spontaneously offers up segments for me to run against my mates but every time that happens the distance ahead (or behind) in the Virtual Partner resets to 0:00.
Is that the expected behavior? I've turned off Segment Alerts in the Run Settings for the Run Activity tonight an I hope that helps tomorrow.
It is a pity that Segment Alerts and the Virtual Partner can't work together. Happy running!
