When you create an activity, you must select Sport to be "Ride", and you cannot check the Tag labeled "Trainer". Currently, no other sports are activities that the NBC can pull into the Challenge.
We do not mean to be that exclusionary and we intend to include three other sports:
E-Bike Ride (only pedal assisted, NOT throttle controlled)
We do not have a timeline for resolution. In meantime, check back before May 1st to see if its resolved. If it is not, feel free to log your rides on ellipticals, E-Bikes, and Handcycles, as rides Thanks for your patience.
