Calculate another marathon pace 🔎
Knowing your pace per mile or km is essential when training for a marathon or even finally running that big marathon you've been preparing years for. The easiest way to know if you're on track for your goal is to know what average pace you need to achieve your goal and consult your smartwatch or running watch, which will have the capability to tell you what your average pace is at any point on your run. That's a whole lot easier than trying to figure out what your total time should be at any particular point in a race.
Using this information, if you're at the halfway point or nearing the end of the marathon and your plan was to run it in 1:51:13, your average pace would have to be 4:14 per mile or 2:38 per km. If you're ahead of that pace, good job! Keep it up. If you're behind, dig down deep and find that extra gear so you can make it happen.
