The standard to brief

The athlete pedals and pushes until the monitor shows the target calories (or distance). Feet stay on the pedals while working; the athlete may stop and rest on the seat.

Common no-reps

  • Getting off before the monitor reaches the target.
  • Starting before the judge has reset the monitor.

Judging notes

  • Use the same bike model in every lane if you can. If you mix models, publish which bike each lane uses, because calorie counts are not guaranteed to match between makes.
  • Reset the monitor between heats and check it reads zero before the start.

Setting it up in a gym

  1. Adjust seat height to the athlete before their heat (put the seat height on the heat sheet notes if they ask).
  2. Check batteries in every monitor the night before.

Equipment

  • Fan bikes (same model per lane)
  • Spare batteries
  • Towels — fan bikes blow sweat everywhere

Scaling for beginners

Lower the calorie target for scaled divisions.
