Running Split Calculator
Create an even, negative, or positive running split schedule from a target distance, finish time, and checkpoint interval in miles or kilometers.
Race Time Predictor
Predict a running finish time at a new distance from a recent race performance using the Riegel endurance model and an adjustable fatigue exponent.
VO₂ Max Calculator
Estimate VO₂ max from a Cooper 12-minute run, a 1.5-mile run, or a Rockport one-mile walk with method-specific validation.
Cycling Power-to-Weight Calculator
Calculate cycling watts per kilogram from power and rider weight, with pounds or kilograms and an optional rider-plus-bike system ratio.
Cycling FTP Zone Calculator
Calculate seven cycling power-training zones from a direct FTP value or an estimated FTP equal to 95% of a 20-minute test average.
Critical Swim Speed Calculator
Calculate critical swim speed from 400 and 200 time trials in meters or yards, with pace per 100 and speed in meters per second.
Swimming Stroke Rate Calculator
Calculate swimming stroke rate from counted strokes and elapsed time, with results in strokes per minute and cycle rate where applicable.
Golf Handicap Calculator
Estimate a World Handicap System Handicap Index from 3 to 20 recent score differentials or score, rating, slope, and PCC entries.
Bowling Score Calculator
Score a complete ten-pin bowling game from frame notation, including strike and spare bonuses through the tenth-frame fill balls.
Baseball Batting Average Calculator
Calculate baseball batting average from hits and official at-bats, with hit rate and remaining hits needed for a target average.
Baseball ERA Calculator
Calculate baseball earned run average from earned runs and innings pitched, accepting standard .0, .1, and .2 baseball inning notation.
Vertical Jump Calculator
Calculate vertical jump height from standing reach and maximum jump reach in inches or centimeters, with unit conversion and range context.

Why sports estimates can differ
Performance and scoring inputs depend on protocol, timing, course or pool conditions, equipment, fatigue, environment, officiating, and sample size. Keep test conditions consistent and rely on the relevant governing body for official competition records.
- Race projections assume comparable preparation and conditions across distances.
- Field-test VO₂ max and cycling FTP are estimates, not direct laboratory measurements.
- Swimming results depend on course length, turns, timing, pacing, and stroke-count consistency.
- Golf, bowling, and baseball tools require the official scoring inputs described on their pages.
Sports Performance Notice: These tools provide educational calculations. Training changes, return-to-play decisions, and official scoring should follow qualified professional guidance and current governing-body rules.
Sports & Performance Calculator FAQs
Are the Sports & Performance calculators free to use?
Yes. All 12 calculators run in the browser without a paid account or required sign-up.
Are Pace Calculator and One Rep Max Calculator duplicated here?
No. Those existing Health & Fitness tools remain in their original category and are linked contextually where useful.
Do these calculators support U.S. customary units?
Yes. Relevant tools support miles, yards, feet, inches, pounds, baseball innings, and U.S. sport conventions, with metric alternatives where appropriate.
Can these tools replace a coach or official scorer?
No. They provide validated educational calculations; official rules, qualified coaching, and authorized scoring records control formal decisions.
Which tool creates a complete race checkpoint schedule?
The Running Split Calculator builds checkpoint-by-checkpoint schedules, while the Race Time Predictor projects one race performance to another distance.
Which calculators use official U.S. sport rules?
Golf Handicap, Bowling Score, Baseball Batting Average, and Baseball ERA use formulas and conventions documented by U.S. governing or professional organizations.
Why might field-test results differ from laboratory measurements?
Environment, pacing, timing, equipment, technique, fatigue, and test protocol can change field-test estimates.
Do results clear when I change an input?
Yes. Each new calculator clears a stale result immediately after an input change and waits for a fresh calculation.
