Cycling Data Lab

Enter a segment's distance, elevation gain and power output to calculate your finishing time - or set a target time and find the watts required. Log in and set up your rider profile (FTP & W') to get an automatic personal best estimate on any segment, perfect for pacing strategy and KOM attempts.

Enter your chainrings, cassette sprockets and wheel size to generate a complete speed table for every gear and cadence combination. Works with road, gravel and mountain bike drivetrains - ideal for choosing the right gearing before a race or a new groupset purchase.

Input 3 all-out efforts at different durations to calculate your Critical Power (CP) and W' (W-prime). Visualize your power-duration curve, estimate your Functional Threshold Power (FTP), and save the results to your rider profile for use in other tools.

Enter your FTP and rider weight to calculate personalized Coggan power training zones in both watts and W/kg. Use the zones to structure interval workouts, base training and race-day pacing for maximum performance gains.

Upload .FIT activity files from Garmin, Wahoo or Hammerhead devices to visualize synchronized charts for power, speed, cadence, heart rate and altitude. Crop specific segments and export the processed file - great for isolating race efforts or removing junk data before analysis.

Upload a FIT file recorded on your target course to split the route into gradient segments and estimate your best finishing time. The simulator uses your Critical Power and W' to model pacing across every segment, accounting for terrain, air resistance and drivetrain losses.
