Race Time Improvement Calculator

What our calculator offers you?

To find out improved running times, all you need to do is to fill in the race result you want to improve. All the rest is done by our calculator. Our calculator comes up with the following numbers:
  • race time improved by 1%
  • race time improved by 2%
  • race time improved by 3%
  • race time improved by 4%
  • race time improved by 5%
  • race time improved by 7%
  • race time improved by 10%
You can see running times in different units – they can be displayed in hours:minutes:seconds, only secondsminutes or hours, even few more combinations. Choose the best option yourself. If you need some custom % time improvements (which are not on the list), open the Advanced mode. Here, you can type in a particular value of percent improvement. The improved result will be displayed below.

Some Math Behind Running?

Race time improvement calculator is based on simple time transformations. For example:

  1. target time improvement = 5% so, the new time will be:
  2. improved time = 95% of race time and a formula for that:
  3. improved time = race time * 0.95 – here it is!

You can calculate all the remaining time improvements in a similar way. If you are interested in calculating percentage changes or improvements in other areas of life, visit our percentage change calculator. It is more general and thus can deal with more problems and questions.

Harder, longer, faster – improve your race time

The longer you run, the more you train, the more difficult is to cut minutes off your time. Probably you know that observation very well. Sometimes using a percentage to plan running improvements is much more practical. Highly trained athletes should expect improvements in the 2-4% range, while newbie runners can usually look for slightly better rates of initial enhancements
