Jumping speeds while running

I just started swift. I have the runn sensor hooked to my treadmill but when I’m running aat a steady speed it jumps my speed up five to ten miles faster. What can I do to fix it?

Do you mean it jumps by 0.5 - 1mph faster than the treadmill is reporting?

You need to calibrate the RUNN to your treadmill. NPE have an app called Configurez to do this. Download it and connect via Bluetooth to the RUNN and it’ll allow you to calibrate both speed and elevation albeit elevation isn’t used by Zwift so I wouldn’t worry.
