  • Sorry if I missed it, but is there an 'official' way of measuring distance indoors? I do my turbos on a Wahoo with my TT bike. It's got a single 56T chainring so all the distances recorded for workouts are massive. I'm doing the exact same effort as if I did it in 34x28 but if I did that the distance would be much lower.

  • Nope. The KICKR etc are changing load depending on cadence and power requirement so it has no idea what gear, wheels, bike, etc.

    I've just been dumping my TR workouts into Garmin and sending that distance.

    "Speed readings are not reliable in ERG mode because the trainer will automatically adjust the resistance to ensure the rider is matching their wattage target — regardless of their gear or speed.

    For example, a rider could shift gears and/or increase their cadence to bring their speed from 20-40mph during an interval with a prescribed wattage of 250. In order to keep the rider at 250 watts, the smart trainer will automatically adjust the resistance to make up for the change in speed. This means the rider's speed readings will indicate 40mph while their watts remain at 250. If the rider shifts back down to 20mph, the trainer will again adjust accordingly so they are still holding 250 watts."
