Popular race targets
A sub-30-minute 5K needs 6:00 min/km. A sub-1-hour 10K needs 6:00 min/km. A sub-2-hour half marathon (21.1 km) needs about 5:41 min/km, and a sub-4-hour marathon (42.2 km) about 5:41 min/km as well. Most training should be at an easy, conversational pace, 60–90 seconds slower than race pace.
