Frequently Asked Questions — 5K (5.0 km / 3.11 mi) in 40 Min
What pace per km and per mile is needed for a 40-minute 5K (5.0 km / 3.11 mi)?
To finish a 5K (5.0 km / 3.11 mi) in 40 minutes, you must maintain an average pace of 8:00 per kilometer (12:52 per mile), which equals an average running speed of 7.50 km/h (4.66 mph) and 192 seconds per 400m track lap.
Should I run an even split or a negative split for a 40-minute 5K (5.0 km / 3.11 mi)?
Exercise physiology studies show a 1% to 2% negative split (running the first half ~2–3 seconds per km slower than 8:00/km and accelerating in the final third) minimizes early lactate accumulation and glycogen depletion.
