The TT HUD over Zwift: now 273 W with live power on target, next 373 W in 1.68 km, W′ 19.6 kJ left, finish 14:46 on plan The TT HUD nine seconds before a change: the next target in amber with its countdown The TT HUD in the pen: starts in 0:09, the strategy and the plan time
New: Race HUD for Sauce4Zwift

Ride your TT plan over the game

The TT HUD shows the power to hold now, the next change and when it comes, the W′ you have left and the time to go against your plan, right over Zwift. A dial, a stack, an interval list, the field and your rivals too.

  1. Link once: a code from the HUD, typed into the planner.
  2. Pick your time trial in the planner and press Plan this event.
  3. Ride: the plan is armed when you join the pen. Or press Plan it on the bike.

Route Predictor

Route Predictor

How long will that route take you? Every Zwift route timed in minutes from its real profile and surfaces, at the power you choose, on the bike you ride: frame, wheels, upgrade level and tyres. Pick a world, sort by time or XP per hour, and tick off the routes you have done.

  • Real route profiles and surfaces
  • Your bike, wheels and tyres
  • Solo or in a group
  • Badge tracker with XP per hour

Zwift Physics Lab

The speed model behind the planners, opened up with charts. Solve speed, power or W/kg for your bike and the road, then see where your watts go, what a kilo costs, which bike is fastest at each gradient, what the draft is worth, how surfaces and tyres roll, how long you can hold a power and your time on a real route.

  • Nine experiments, redrawn for your numbers
  • Your bike, wheels, tyres and draft position
  • Light and dark, with a table view of every chart
