Bike
Threshold power, training load, and bike pacing support for triathletes.
Bike metrics matter most when they improve pacing discipline and protect the run.
FTP Calculator
Estimate functional threshold power and turn it into cleaner bike zones, Sweet Spot targets, and triathlon pacing anchors.
FTP is most useful when it helps you train well and pace the bike without wrecking the run.
Results: FTP • W/kg • Power zones • Sweet Spot • Triathlon pacing targets
Bike TSS
Calculate bike Training Stress Score, Intensity Factor, and target ride stress with cleaner load guidance for self-coached triathletes.
Bike TSS works best when it helps you plan load honestly, rather than pretending one number can predict recovery by itself.
Results: TSS • Intensity factor • Load interpretation • Work and VI • Target TSS planning
Power-to-Weight
Calculate your watts per kilogram, see where you rank against cycling and triathlon benchmarks, and get race-specific context for every triathlon distance.
W/kg is the single best summary of cycling ability relative to body mass. Use it to benchmark fitness and set realistic bike-leg targets.
Results: W/kg result • Performance classification • Benchmark comparison • Triathlon context • Improvement tips
Gear Ratio
Calculate gear ratio and speed at any cadence, compare gearing options, and get triathlon-specific cadence and gear-selection advice.
Use gear ratio and cadence data to select the right gearing for your course profile and protect your run legs in triathlon.
Results: Speed at cadence • Gear ratio • Speed-at-cadence table • Gear classification • Triathlon context • Recommendations
Power Zones
Enter your FTP to see all 7 Coggan power zones with watt ranges, training purpose, example workouts, and triathlon pacing context.
Power zones turn a single FTP number into a structured training framework. Use them to target specific adaptations and pace the bike leg intelligently.
Results: Zone table with watt ranges • Visual zone chart • Training insights per zone • Triathlon pacing context • W/kg insight (if weight provided)
Bike Pace
Calculate cycling time, speed, or pace for any distance, with race presets for Sprint, Olympic, 70.3, and IRONMAN. Includes course, wind, and bike-type adjustments.
Solve for bike time, speed, or pace with built-in triathlon race presets, course adjustments, and what-if speed-impact analysis.
Results: Primary result (time, speed, or pace) • Conversion table • What-if speed impact • Race split projections (Race Planner mode)
Tire Pressure
Evidence-based tire pressure recommendations using Silca and SRAM research. Accounts for rider weight, tire width, tubeless/tubed setup, hookless rims, and road surface quality.
Get optimal front and rear tire pressures backed by modern rolling resistance research. Lower is often faster on real roads.
Results: Front and rear PSI recommendations • Bar conversion • Hookless maximum pressure warning • Speed vs comfort tradeoff analysis • Setup recommendations
Cadence Calculator
Find your optimal cycling cadence for any terrain and race distance. Calculate speed from cadence and gearing with triathlon-specific run-preservation guidance.
Get science-based cadence recommendations that account for terrain, power, race distance, and the triathlon need to preserve running legs off the bike.
Results: Optimal cadence recommendation • Speed at recommended cadence • Cadence-to-speed comparison table • Gear ratio analysis • Triathlon-specific run preservation note
Bike Split
Plan triathlon bike splits using power-based pacing. Get per-segment time estimates, nutrition timing, and TSS projections for any course profile.
Turn your FTP and course profile into a detailed segment-by-segment bike race plan with power targets, speed estimates, and nutrition timing.
Results: Total estimated time and average speed • Per-segment power, speed, and time • Nutrition timing plan • TSS and Intensity Factor estimates • Pacing recommendations
