Pace Calculator for Runners is an app that’s designed to do one thing well. When training for a recent marathon, I found myself constantly Googling for pace tables with finish times. I built this app so I could quickly answer the question, “if I ran at a 7:30 pace, what would my marathon time be? What about a 5K?” Key features I’ve included: - The +1m and -1m buttons at the bottom allow you to easily skip between paces by the minute. - Tapping the top bar lets you change the race distance. You can choose from a set of default, or enter in a custom distance of your own in miles or kilometers. - The selected pace and race distance are saved, so next time you open the app, you won’t have to re-enter any information.
