Frequently Asked Questions — 10K (10.0 km / 6.21 mi) in 38 Min
What pace per km and per mile is needed for a 38-minute 10K (10.0 km / 6.21 mi)?
To finish a 10K (10.0 km / 6.21 mi) in 38 minutes, you must maintain an average pace of 3:48 per kilometer (6:07 per mile), which equals an average running speed of 15.79 km/h (9.81 mph) and 91 seconds per 400m track lap.
Should I run an even split or a negative split for a 38-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 3:48/km and accelerating in the final third) minimizes early lactate accumulation and glycogen depletion.
