Simple ways to test your running fitness (no lab required)
Have fun finding your baseline (without spending any money at all)

Most of us are curious about how fit we actually are. The gold-standard answer usually comes from a sports lab, where aerobic capacity and other markers can be measured directly. But there are also a few simple, and even fun, ways to get a sense of your running fitness without stepping into one.
Either of the following can also give you a snapshot of your aerobic fitness, and they’re easy to repeat later to track your progress.
The Cooper test
The Cooper test is named for Kenneth H. Cooper, the doctor who developed it in 1969 while working with the U.S. Air Force and studying ways to evaluate aerobic fitness in large groups without lab equipment. In Cooper’s original research, participants completed both a treadmill VO₂ max test in a lab and a 12-minute run outdoors. The distance they covered in 12 minutes showed a strong correlation with their measured VO₂ max.
The Cooper test is best completed on a track or flat road. Post-run, if you measured your distance in kilometres, multiply your total by 22.351 and subtract 11.29. If you ran in miles, multiply the total by 35.97 and subtract 11.29. That number gives you an estimate of your VO2 max—basically, how well your body delivers oxygen to your muscles during intense effort. You can also use an online calculator, such as this one.
The Rockport walking test
Exercise physiologists developed the Rockport one-mile walk test at the University of Massachusetts Amherst as a safe, lower-impact way to estimate aerobic fitness. Instead of an all-out run, participants walk one mile as fast as they can, and record both their time and heart rate at the finish. Those numbers are then entered into an equation to estimate VO₂ max. (You can also use an online calculator such as this one.)
The Rockport test is based on a well-established principle in exercise physiology: as exercise intensity increases, heart rate and oxygen use rise in predictable ways. People with higher aerobic fitness generally complete the mile faster, and finish with a lower heart rate, than those with lower fitness levels.
Before (and after) you test
Make sure to warm up well, so that you can perform at your best during whichever test you choose—some quick walking and some mobility drills are a great idea. Sports physiologists recommend waiting at least six to eight weeks before taking the test again to see how much you’ve improved.
