An 8-week 5K plan combines 3–4 runs per week: one interval session (VO2 pace), one tempo run, one long easy run of 6–8 miles, and recovery jogs — peaking fitness in week 7 with a taper in week 8.
Who this is for
Runners who can run 20–30 minutes continuously and want to improve 5K time or complete their first race.
8-week progression
| Weeks | Interval focus | Weekly mileage |
|---|---|---|
| 1–2 | Short reps (400 m) | 12–15 mi |
| 3–4 | 800 m–1K reps | 15–18 mi |
| 5–6 | Race-pace intervals | 18–22 mi |
| 7–8 | Taper + race | 12–15 mi |
Sample interval week
- Tue: 6 × 800 m @ 5K pace, 90 s jog recovery
- Thu: 4 mi tempo @ 10K pace
- Sat: 7 mi easy long run
- Sun: 3 mi recovery
Common mistakes
- Running intervals too fast — target consistent 5K pace, not sprint pace.
- Skipping easy days between hard sessions.
- No taper — racing fatigued from peak mileage week.
