The 5K Runner Guide
Everything from running your first 5K to breaking 20 minutes. Training plans, pace targets, race strategy, and the fuelling that actually works.
Why the 5K is the Most Important Distance
The 5K is the most popular race distance in the world. It is long enough to feel like an accomplishment, short enough to race every month, and accessible enough for someone who has never run before to finish in eight to ten weeks.
It is also the distance that will teach you the most. Your 5K time is the single best predictor of your 10K, half marathon, and even marathon times. Train the 5K well and every other distance gets easier.

How to Train for Your 5K
First 5K (8-10 weeks)
Follow Couch to 5K. Three runs per week, alternating run and walk intervals. By week 9, you can run 30 minutes continuously.
Sub-30 min (6-8 weeks)
Already running 5K in 35+? Add one interval session (6 x 400m at 1:40) and one tempo run (2 x 10 min at 6:15/km) per week.
Sub-25 min (8-12 weeks)
15-20 miles per week. Interval work at 4:30/km. Tempo runs at 5:10/km. Long runs up to 8km. Strength training twice a week.
Sub-20 min (12-24 weeks)
25-35 miles per week. VO2max intervals. Threshold runs. At least one year of consistent training beforehand.
The first 5K is the hardest. The next hundred are the point.
