Frequently Asked Questions — Half Marathon (21.1 km / 13.1 mi) in 90 Min
What pace per km and per mile is needed for a 90-minute Half Marathon (21.1 km / 13.1 mi)?
To finish a Half Marathon (21.1 km / 13.1 mi) in 90 minutes, you must maintain an average pace of 4:16 per kilometer (6:52 per mile), which equals an average running speed of 14.06 km/h (8.74 mph) and 102 seconds per 400m track lap.
Should I run an even split or a negative split for a 90-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 4:16/km and accelerating in the final third) minimizes early lactate accumulation and glycogen depletion.
