Sports calculators
Train with the numbers on your side: heart-rate zones, running pace, VO2 max and 1RM. TudoCalc's sports calculators help you plan workouts and track progress.
Heart rate zones
Calculate your maximum heart rate and training zones for fat burning and conditioning.
Running pace
Calculate your pace (min/km) and average speed from the run distance and time.
1RM (one-rep max)
Estimate your one-rep max (1RM) and the loads to train at different intensities.
VO₂ max (Cooper test)
Estimate your VO₂ max with the Cooper test: distance covered in 12 minutes.
FFMI
Calculate your FFMI, the index that measures how much lean mass you carry for your height.
Race time predictor
Estimate your time at another distance from a race you've already run (Riegel formula).
Target heart rate (Karvonen)
Calculate personalized training zones with the Karvonen method, which uses your resting heart rate.
Swim pace
Calculate your swim pace per 100 meters, speed and pace per 50 m, from distance and time.
Training load (%1RM)
From your one-rep max (1RM), see the ideal weight for each rep range.
Steps to distance
Convert steps into distance and calories, using your height to estimate stride length.
