On September 30, 2026, Runner's World published a training guide on improving 5K performance. The article notes that about 85% to 90% of the energy in a 5K race comes from the aerobic system, so coaches recommend scheduling 4 to 6 Zone 2 aerobic easy runs per week, with heart rate kept at 60% to 70% of maximum heart rate, to build a solid aerobic base. On that basis, add 1 to 2 interval sessions per week, including 400-meter repeats, hill runs, tempo runs, or fartlek runs, to improve lactate handling capacity. In addition, the article recommends 2 to 3 strength training sessions per week, focusing on strengthening the glutes, hamstrings, quadriceps, and calves to improve running economy and overall performance. This is currently the only report on the event, with no follow-up developments or contradictory claims.
To run a faster 5K, coaches recommend four to six Zone 2 aerobic runs per week at 60 to 70 percent of max heart rate, since about 85 to 90 percent of a 5K relies on the aerobic system. Add one to two interval sessions weekly, such as 400-meter repeats, hill repeats, tempo runs, or fartleks, plus two to three strength workouts targeting glutes, hamstrings, quadriceps, and calves.
