What's a Good Running Pace? A Realistic Guide by Age and Goal

“What's a good running pace?” is one of the most common questions new runners ask, and the honest answer is: it depends. It depends on your age, how long you have been running, what distance you are training for, the terrain, the weather, and even how you slept. A pace that exhausts one person is an easy warm-up for another. Rather than chase a single magic number, it is far more useful to understand the ranges and how to find yours.

There is no universal “good” pace

As a very rough reference, many recreational runners settle somewhere between 9 and 12 minutes per mile (about 5:30 to 7:30 per kilometer) for an easy run. Beginners often start slower, and that is completely normal. Competitive amateurs may cruise at 7 to 8 minutes per mile, while elite marathoners hold under 5 minutes per mile for over two hours. The spread is enormous, and comparing yourself to the top of it is a recipe for discouragement.

How age factors in

Running performance tends to peak somewhere in the late twenties to mid-thirties for most distances, then declines gradually. The decline is slow at first — often barely noticeable through your forties — and steepens later in life. But age is far from destiny: a well-trained 50-year-old routinely outruns an untrained 25-year-old. Consistency and years of training matter more than the number on your birth certificate. Treat age as one input that shifts the realistic range, not a ceiling.

Pace by goal, not just by speed

Experienced runners deliberately train at several different paces, because each one builds something different:

• Easy pace — the majority of your weekly mileage; builds aerobic base and aids recovery.
• Tempo pace — “comfortably hard,” sustainable for around an hour; raises your lactate threshold.
• Interval pace — short, fast repeats with rest; sharpens speed and running economy.
• Race pace — the specific pace you aim to hold on race day, rehearsed in training.

Knowing your easy pace also keeps you honest: if every run feels hard, you are probably running your easy days too fast and leaving no room to push when it counts.

Predicting race times with the Riegel formula

Once you have a recent race or hard effort at one distance, you can estimate your time at another using Peter Riegel's formula, a model that has held up well for decades:

The exponent of 1.06 captures a simple truth every runner knows: you cannot hold your 5K pace for a marathon. Pace naturally slows as distance grows. The prediction is most accurate when the two distances are reasonably close and you have trained specifically for the longer one. Our pace calculator runs this for you — enter one result and it forecasts the others.

Setting a realistic target for yourself

To find a pace worth aiming for, start from where you are, not where you wish you were. Run a recent effort honestly, use it as your baseline, and set the next goal a small, sustainable step beyond it. Improvement in running is measured in weeks and months of consistency, not single heroic workouts. Track your easy pace over a training block and you will usually see it drift faster at the same effort — quiet proof that the work is paying off.
