Plan faster rides with wind, CdA and power modelling

Unlimited helps you understand how weather, position and pacing affect your ride before you set off — and what cost you time afterwards.

Unlimited includes
  • CdA and aero analysis — see how your position and setup affect speed.
  • Wind and weather impact — understand headwinds, tailwinds and route conditions.
  • Power and pacing predictions — know the watts needed for your target time.
  • Race, TT and segment planning — choose the right effort, setup and day to ride.
  • Deeper Strava ride analysis — see where time was won, lost or waiting to be found.

Thanks for upgrading

PayPal is confirming your subscription. What is the first thing you are excited to try or use more of?

A sentence or two is perfect. Your words help decide what gets improved next.

Unlock Weather Trends

Premium turns your ride history into weather intelligence, so you can see how wind, temperature, rain and air density shape your performance over time.

Track changing conditions

Compare weather trends across weeks, months and seasons from your recorded activities.

Connect weather to performance

Use power duration and Power vs CdA views to understand when you are holding power and aero position well.

Find your weather outliers

Spot the rides with the toughest headwinds, wettest conditions and biggest air penalty.

Make Surface your default?

Open myWindsock in Surface by default for the newer map, route planning and cycling-specific wind modelling experience.

Keep Surface as your default experience?

Choosing No will switch you back to the Classic myWindsock experience, which is still available. You can always switch back to Surface later.

Lua

myWindsock Lua Simulation Script

A very powerful tool to customise your simulation. Write your own functions to modify the inputs into the simulation.

Example 1: simple kJ-limited boost 

                    -- Declaring Global energy budget (persists between steps)
                    kj = kj
                    or
                    25
                    -- Boost power while we still have kJ left and we're slower than the air (headwind)
                    if
                    speedMs
                    <
                    airSpeedMs
                    and
                    kj >
                    0
                    then
                    boost =
                    power
                    *
                    0.2
                    -- 20% boost
                    power
                    =
                    power
                    + boost
                    -- apply boost
                    boostKj = boost *
                    stepS
                    /
                    1000
                    -- convert W·s to kJ
                    kj = kj - boostKj
                    -- Deduct boost from Global energy budget
                    end

Example 2: overwrite simulation inputs 

                    -- Directly set CdA and massKg
                    cda
                    =
                    0.4
                    massKg
                    =
                    95

Mutable variables (Changeable)

  • power – rider power output (W)
  • cda – drag area (m²)
  • massKg – rider + bike mass (kg)
  • crr – coefficent of rolling resistance
  • drivetrainEfficiency – drivetrain efficiency (0 - 1)

Immutable (read-only)

  • elapsedS – seconds from start
  • stepS – step duration in seconds
  • distanceM – total distance in metres
  • altitudeM – altitude in metres
  • speedMs – speed in metres per second
  • airSpeedMs – air speed in metres per second
  • drivetrainEfficiency – drivetrain efficiency (0 - 1)
  • slope – gradient (0 - 1)
  • crr – rolling resistance coefficient
  • windBearing – wind direction in degrees
  • windSpeedMs – wind speed in metres per second
  • windSpeedShearedMs – sheared wind speed in metres per second
  • temperatureC – temperature in degrees Celsius
  • humidity – relative humidity (0 - 1)
  • travelBearing – travel direction in degrees
  • airDensity – air density in kg/m³

Tips

  • Use globals for memory, e.g. kj = kj or 25 .
  • Avoid infinite loops (like while true do ... end ) – they are blocked.
  • Keep logic light – your script runs thousands of times per ride.
