I've made a new calculator today. You can enter a time and distance, and calculate the average pace. Nothing fancy, bu sometimes it's handy to do a quick calculation like that.
Let's say that you ran a 15K race in 1 hour and 15 minutes. What pace have you run at? It turns out that you had an average pace of 5 minutes per kilometer. And what about a 10M in 59 minutes and 58 seconds? Your pace was 3:44.
Calculate pace from time and distance
