What are RoboPacers?

Zwift's RoboPacers are AI-controlled riders that cruise the virtual roads at a fixed watts-per-kilogram (W/kg) pace. They range from Sofia's gentle 0.8 W/kg all the way up to Constance's demanding 4.2 W/kg. Enter your weight below to see the exact wattage you'll need to stay in the draft of each one.
