IronSplit

Your race-day command center

Your goal isn't a wish.
It's a plan.

See exactly where you would finish. Set your swim, bike, and run splits and pressure-test your placing goal against real finisher data, then send the whole plan to your crew.

Premium · Bike Power Plan

Ride your race on the optimal plan.

A course-specific power plan: the exact watts to hold on every climb, descent, and flat for the race you picked. Built on a real model of your numbers, it estimates the minutes you save versus riding a steady target. First plan is free.

  • Watts for every climb, descent, and flat

    Not a single flat target. A course-specific plan computed for the exact race you picked.

  • Built on a real model

    FTP or critical power, W', CdA, Crr, rider and bike mass, and riding position: the dials you already tune.

  • See the minutes you save

    It estimates how much time the plan saves versus riding a steady target, the whole edge of pacing to the course.
