Frequently Asked Questions — 50K Ultramarathon (50.0 km / 31.1 mi) in 360 Min

What pace per km and per mile is needed for a 360-minute 50K Ultramarathon (50.0 km / 31.1 mi)?
To finish a 50K Ultramarathon (50.0 km / 31.1 mi) in 360 minutes, you must maintain an average pace of 7:12 per kilometer (11:35 per mile), which equals an average running speed of 8.33 km/h (5.18 mph) and 173 seconds per 400m track lap.
Should I run an even split or a negative split for a 360-minute 50K Ultramarathon (50.0 km / 31.1 mi)?
Exercise physiology studies show a 1% to 2% negative split (running the first half ~2–3 seconds per km slower than 7:12/km and accelerating in the final third) minimizes early lactate accumulation and glycogen depletion.
