Frequently Asked Questions — 10K (10.0 km / 6.21 mi) in 48 Min
What pace per km and per mile is needed for a 48-minute 10K (10.0 km / 6.21 mi)?
To finish a 10K (10.0 km / 6.21 mi) in 48 minutes, you must maintain an average pace of 4:48 per kilometer (7:43 per mile), which equals an average running speed of 12.50 km/h (7.77 mph) and 115 seconds per 400m track lap.
Should I run an even split or a negative split for a 48-minute 10K (10.0 km / 6.21 mi)?
Exercise physiology studies show a 1% to 2% negative split (running the first half ~2–3 seconds per km slower than 4:48/km and accelerating in the final third) minimizes early lactate accumulation and glycogen depletion.
