Why this conversion matters
UK and US road races, parkruns measured in km, and US-based training plans written in miles all mean runners frequently need to convert between the two — especially when following an international training plan or comparing personal bests set on courses measured in different units.
FAQ
Do parkruns use miles or kilometres?
Parkrun events worldwide are a fixed 5 km (3.1 miles) distance, standardised regardless of country, so no conversion is needed for parkrun times specifically — but comparing to a mile-based time trial does need converting.
Why do US road races use miles when most of the world uses km?
The US retains the imperial system for everyday and sporting distance measurement, unlike most countries, which adopted metric race distances.
Is a 5-mile run the same as an 8K?
Close but not identical — 5 miles is 8.047 km, so an '8K' race (8.0 km) is very slightly shorter than a 5-mile race.
