Apologies if this has been answered but I’m wondering if I can do a spindown in the TR desktop app in the middle of rest intervals without having to exit the workout?
Yes. Just stop pedalling to pause the workout, go to devices, pick the kickr, pick calibrate.
Dunno how it works with the desktop app, but with the mobile app, just stop pedalling and cluck the … to get to the menu. Once calibrated, click back on your phone to get back to the workout, and start pedalling again.
Desktop Win 10
Just select devices, choose which device, calibrate, return to workout
