Every backyard ultra lap is 4.167 miles (6.706 km), and a new lap starts every hour. Enter laps, miles or kilometres and the other two fill in. Set how much rest you want at the end of each lap and you'll see the pace that gets you there.
24 laps is exactly 100 miles. Most runners aim for 45 to 50 minute laps, which leaves 10 to 15 minutes to eat, drink and sort feet before the next bell.
