How far is a 5K in miles?

A 5K (5 kilometers) equals 3.10686 miles. This calculator uses the exact 5.0 km distance for all calculations.

What is a good 5K finish time for beginners?

A good beginner target is 30–35 minutes, which equals a pace of roughly 6:00–7:00 min/km (9:40–11:15 min/mi). The most important thing is to finish comfortably — you can aim for faster times as your fitness improves.

How do I calculate my 5K pace?

Divide your total finish time (in seconds) by 5 to get seconds per kilometer, then convert to minutes and seconds. For example, a 25:00 finish equals 300 seconds ÷ 5 = 60 seconds/km, or a pace of 5:00 min/km. This calculator does that math instantly.

What is a negative split strategy for a 5K?

A negative split means running the second half of the race faster than the first. For a 5K, many runners aim to run km 1 slightly slower, km 2–3 at goal pace, and km 4–5 faster. The split table in this calculator shows your ideal time at each kilometer for an even-pace strategy.

Can I use this calculator for treadmill paces?

Yes. Treadmills display speed in km/h or mph. Enter your target pace in min:sec per km or per mile, and the calculator will show your equivalent 5K finish time along with your speed in km/h and mph.

What does min/km mean in running?

Min/km (minutes per kilometer) is the time it takes to run one kilometer. A pace of 5:30 min/km means each kilometer takes 5 minutes and 30 seconds. Slower runners have higher min/km numbers; faster runners have lower numbers.
