| Pacing Calculator |
| Make your own marathon pace chartGenerate a pacing chart in per mile or per kilometer increments.Enter your race distance (5K,10K, half-marathon or marathon), your goal finishing time,
and the increments (every mile, every 5 miles ,every km) that you wish to display. |
| Age-graded performance Calculator |
| Calculate your age-graded performance.Predict the equivalent open (30 years or younger) time for a particular distance, as well as the percentile score.The program covers men and women, age 40-70 for the 5K,10K, half-marathon and marathon distances. |
| Race Time Prediction |
| Estimate how long it will take to run a specified distance, based on a previous race result.Both metric and non-metric calculators are available.This type of predictive analysis is more accurate when the two distances are relatively similar (e.g 5K and 10K). |
| Interval Pace Calculator |
| Estimate your optimal interval training pace, based on your current 5K race time.AT(anaerobic threshold) and VO2-Max pace is calculated. |
| Heart-rate zone Calculator |
| Estimate your heart-rate zones for easy running, anaerobic threshold (AT) and VO2 Max workouts.The training zone values are calculated using the Karvonen formula: |
| Calorie Calculator |
| Estimate the amount of calories you burn at a given running pace.The calculation is based on a formula derived from a study of the net energy expenditure for running 1 hour on a horizontal surface. |
