System Requirements

- Working ZWIFT account, with in-
   game TT bike enabled

- ZWIFT Companion app on phone or
   other mobile device

- 'Smart'-trainer (ex. Wahoo Kickr),
   or a traditional indoor trainer with
   a bike-based power meter

- Unfortunately, though the ZWIFT
   software works with wheel-based
   speed sensors, we cannot allow
   them as part of the Competitive
   Class at this time.
