Frequently Asked Questions — Half Marathon (21.1 km / 13.1 mi) in 75 Min
What pace per km and per mile is needed for a 75-minute Half Marathon (21.1 km / 13.1 mi)?
To finish a Half Marathon (21.1 km / 13.1 mi) in 75 minutes, you must maintain an average pace of 3:33 per kilometer (5:43 per mile), which equals an average running speed of 16.88 km/h (10.49 mph) and 85 seconds per 400m track lap.
Should I run an even split or a negative split for a 75-minute Half Marathon (21.1 km / 13.1 mi)?
Exercise physiology studies show a 1% to 2% negative split (running the first half ~2–3 seconds per km slower than 3:33/km and accelerating in the final third) minimizes early lactate accumulation and glycogen depletion.
