The Pure Mathematics of Track Racing: Pacing in the Individual Pursuit, Fixed Gears, and Aerodynamics on the Wooden Track

Removing All the Variables

The allure of track cycling lies in how it strips away nearly every variable that complicates road racing: no wind, fixed gear, no brakes, and a fixed track geometry. What remains is an almost pure mathematical problem of human power output and aerodynamics—which also makes it the cleanest laboratory for studying pacing and aerodynamics.

Environmental Variables: Track vs. Road

Individual Pursuit: The Purest Form of Pacing

The individual pursuit is the ideal model for pacing science: a fixed distance with no external interference, where the rider must find the optimal allocation between the W’ budget and sustainable power output. The opening segment inevitably exceeds the average pace (accelerating from a standstill), after which precise control is required to avoid burning through the early reserves and causing a power collapse later—this is entirely consistent with the W’ arithmetic of time-trial pacing, only more pure.

The Cadence Shackle of Fixed Gearing

A track bike has a fixed gear and cannot coast, meaning cadence and speed are directly locked together. Choosing a gear ratio is an irreversible pre-race gamble between “starting acceleration capability” and “top-speed cadence ceiling.” A gear too large makes the start heavy; too small and your cadence blows up at top speed, causing efficiency to collapse. This is a decision unique to track racing, where a large portion of the outcome is decided before the race even begins.

The Aerodynamic Particularities of a Wooden Track

• No indoor wind makes CdA nearly the only aerodynamic variable, amplifying the benefits of body position
• Banked corners allow riders to maintain high speed through the turns, making pacing more continuous
• In team pursuit, the energy-saving effect of drafting is more quantifiable in a windless environment
• Track air density (temperature, altitude, number of people) materially affects record-breaking performances

Why Road Riders Should Also Understand the Track

Track racing isolates pacing, W’ management, and aerodynamics from the noise and presents them individually, making it the best teaching tool for these concepts. Much of the pacing and drafting logic in road time trials and team time trials can be seen most clearly in the pure environment of the track.

Track racing is like putting endurance sport in a vacuum laboratory—remove the wind, remove the gears, remove the brakes, and all that remains is your power curve, your W’ budget, and the courage you had when choosing that gear ratio before the race. It is not glamorous, but it is brutally honest: here, there is no excuse to hide behind the wind or luck.
