Let’s say you want to run a 10K in 50 minutes. You’ll need to cover a kilometer every 5 minutes (or a mile every 8 minutes and 3 seconds), which means a constant pace of 12kph. Once you’ve found your target pace, check out our training tips to learn how to work up to it – and stick to it! 1kph = 0.62137mph. If we calculate the time to walk a 5k at these speeds, the average “usual” walking speed works out to walk a 5k in 64.1 minutes (64 minutes and 6 seconds), while walking a 5k at the average maximum walking speed would take a mere 41.9 minutes (41 minutes and 53 seconds). My calves would burn burn burn for a few weeks everytime I'd run and they'd always be sore. But about three months into, I ran an 18 flat at the UNT course. Then about 2 weeks later, I took off another minute. About a month later I had reached 16:30. Then at the Regional meet I ran a 16:20. Two weeks later at State I ran 15:45. So 12 mph = 5 minutes per mile. 2) How many minutes per mile is 2 mph? To convert from mph into minutes per mile we need to divide 60 by the number of miles per hour. 60 ÷ 2 = 30. So 2 miles per hour is the same as 30 minutes per mile. 3) Tyger runs at a speed of 8 miles per hour. Cefb.
