Understanding Pace (per mile/km)

Pace is the time it takes to cover one mile (or one kilometer), expressed as minutes:seconds per mile (e.g., 8:30/mi). It's the universal language of running speed and the metric you'll use to set training targets, execute workouts, and plan race strategies.

Pace varies significantly by context. A runner might do easy runs at 9:30/mi, tempo runs at 7:45/mi, and race a 5K at 7:00/mi — all representing different effort levels for the same person. Understanding your pace ranges for different effort levels is fundamental to smart training.

Pace is affected by terrain, weather, altitude, and fatigue. A 7:30/mi on a flat road in 50°F weather is very different from 7:30/mi uphill in 85°F heat. This is why many coaches recommend running by effort or heart rate on variable terrain and saving pace targets for flat roads and tracks.

Pace and speed are inverses

Pace and speed are inverses: 6:00/mi = 10 mph; 10:00/mi = 6 mph

GPS watches display real-time pace, thou

GPS watches display real-time pace, though it can fluctuate ±5–10 seconds due to GPS noise

Pace calculators

Pace calculators (McMillan, VDOT) convert race times to training paces

Pro Tips: Pace (per mile/km)

Use a VDOT calculator with a recent race time to determine your training paces

Don't chase pace on hilly or hot days — use effort/HR instead

Auto-lap pace on your watch (per mile average) is more useful than "instant pace" which fluctuates wildly

Know your key paces: easy, tempo, interval, and goal race pace

Frequently Asked Questions About Pace (per mile/km)

Start from a recent race time and use a pace calculator, or simply run at a pace where you can hold a full conversation without gasping. For most runners, easy pace is 1:30–2:30 minutes per mile slower than 5K race pace. If in doubt, slow down — most runners do their easy runs too fast.

Treadmills are imperfect: the belt speed may not be calibrated accurately, and running on a treadmill eliminates wind resistance and terrain variation. Many runners set a 1% incline to approximate outdoor effort. Also, perceived effort on a treadmill is often higher due to heat, boredom, and lack of visual speed cues.
