Drafting physics

Wahoo RGT riding simulation is more like the real world than other virtual racing platforms with respect to cornering, braking, and drafting.

Wahoo RGT implements Real Cloud Physics - cloud-based computers that analyze and understand the rider’s position compared to that of the surrounding athletes. Instructions are then sent to all of the on-screen avatars to establish their position, actions, and movement on the screen. This occurs five times per second.

Some features of riding in Wahoo RGT:

  • You won’t be able to take corners at full speed. To recreate the concertina effect experienced in real life racing when cornering, you’ll experience simulated braking into corners. This may seem slow, but it is based on angles, forces, the line you’re taking, and pedal stroke considerations.
  • In order to pass another rider, you need to be traveling significantly faster or putting out more power. Your avatar will not be shuffled through riders during the pass - instead, you’ll be steered around to overtake (and will have to put in the extra effort associated with passing, as you would in the real world).
  • RGT also shows you how close you are to the rider you’re drafting on and how many watts you’re saving by riding on their wheel.
  • Automated braking will occur to avoid colliding with riders in front of you. You’ll see your power value turn red, indicating braking. You can overcome this by pushing significantly higher power numbers than the rider in front of you - or by approaching them at a significantly higher speed.
  • You will not get pulled into the draft at speeds slower than 16 km/h (unless there is no room to overtake - then you’ll be forced into the draft regardless of speed).



Drift Back - It appears when power gets below the lower threshold

Pull - appears when pulling out of draft, exceeding the upper threshold

Saving - the power saved will be displayed when you are locked in a user's draft

Arrows >>> - The power value below which you'll start to drift back (increase the distance between you and the followed rider). This is also the power which for this instant would maintain the current speed. Assuming the rider in front has constant speed, this power value will keep your speed constant as well and maintain the distance between you.

Arrows <<< - The power threshold to exit drafting and overtake the rider in front. If at current speed the distance between riders is getting too small then auto-braking gets applied as long as power is below this upper threshold.

The power turns red (automated breaking) gets applied in the following scenarios:

  • could be applied during a turn

  • could be to avoid someone else if there is no room to go around (narrow lane or other riders around you), so if there is no room breaking continues even after exceeding the power threshold to overcome user in front. We are continuously improving this scenario.

You will not get pulled into draft at speeds lower than 16 km/h. (If there's no room to overtake then drafting is forced regardless of speed, unless the riders blocking you are stopped)
