Chasing a 22-minute 5K

Goal introduction

A 22-minute 5K means holding around 4:24 per kilometre. Speed alone won’t get you there. You need an aerobic base big enough to hold the rhythm, mental resilience to push past the discomfort, and the confidence that comes from repeatable hard efforts.

Pre-requisites

• Recent 5K time: 25 minutes or under (you should feel comfortable at 5:00/km for 5 km).
• Base mileage: 8 to 10 km of easy running per week should feel manageable.
• Basic speed work: at least one recent session (e.g. 4×400 m).

If those aren’t there, spend 2 to 3 weeks building base first.

How the plan works

Workout	Purpose	Typical pace / effort
Easy run	Aerobic foundation, recovery	5:20 to 5:25/km, conversational
Tempo run	Lactate threshold, “comfortably hard” effort	4:45 to 5:00/km (≈85 % max HR)
Interval	VO₂ max and leg speed	800 m repeats at 4:00/km, 2 min jog recovery
Long run	Endurance, fuel usage	5:25/km, 20 to 30 % slower than race pace
Rest / cross-train	Adaptation, prevent overuse	Light activity (yoga, swimming, cycling)

2	5 km @ 5:20/km	6×800 m @ 4:00/km, 2 min jog	4 km @ 4:45/km	6 km @ 5:25/km	Rest
3	5 km @ 5:18/km	5×1000 m @ 4:10/km, 2 min jog	4 km @ 4:40/km	7 km @ 5:24/km	Rest
4	6 km @ 5:18/km	6×800 m @ 3:55/km, 2 min jog	5 km @ 4:35/km	8 km @ 5:23/km	Rest
5	6 km @ 5:17/km	5×1200 m @ 4:15/km, 2 min jog	5 km @ 4:30/km	9 km @ 5:22/km	Rest
6	7 km @ 5:17/km	6×800 m @ 3:55/km, 2 min jog	6 km @ 4:25/km	10 km @ 5:21/km	Rest
7	7 km @ 5:16/km	5×1000 m @ 4:05/km, 2 min jog	6 km @ 4:20/km	11 km @ 5:20/km	Rest
8	8 km @ 5:15/km	6×800 m @ 3:55/km, 2 min jog	7 km @ 4:15/km	12 km @ 5:20/km (taper)	Rest

Start and finish every session with 5 minutes of easy running. Adjust paces by ±5 % if the effort is too demanding or if weather and terrain demand it.

Detailed workout descriptions

Easy run: keep intensity low enough to chat comfortably. Relaxed shoulders, steady rhythm. Think distance covered, not time elapsed.

Tempo run: 5 minutes easy, then a challenging but sustainable pace (around 85 % max HR) for the target distance. At this effort, you can manage a few words but not full sentences. 5 minutes easy to finish.

Interval session: 10 minutes easy, then the repeats (e.g. 5×800 m). Hit each at goal pace, jog easy for the stated recovery. 10 minutes easy to close.

Long run: your weekly aerobic test. Conversational pace, duration over speed. Use the time to practice race-day nutrition and hydration.

Rest / cross-train: take the day off running. Cycling, swimming, or yoga help circulation and recovery without pounding the joints.

Notes and tips

• Progression: if the load feels excessive, repeat the previous week.
• Recovery: don’t shortchange sleep, water, or protein after tough workouts.
• Pacing: a GPS watch or app helps with splits, adapt for hills and weather.
• Common pitfalls: skipping easy days, pushing intervals past target pace, ignoring minor injuries.
• Mindset: each session is a building block. Steady repetition beats sporadic effort.

FAQ

Q: I missed a hard workout. Can I do it later in the week? A: Move it to an open slot at the same intensity, but keep at least one relaxed run before the next hard session.

Q: My current 5K PB is 27 min. Can I still try this plan? A: It’s a stretch. Spend an extra 2 to 3 weeks on base building (easy runs plus one weekly speed session) before week 1.

Q: How do I adjust paces for hills? A: Effort matters more than pace on hills. Ease off on climbs and let momentum carry you on descents.

Q: I’m sore after interval day. Should I skip the next run? A: A gentle recovery jog or cross-training is fine. If soreness is acute or lingers, add an extra rest day.

Q: What if I’m recovering from a minor injury? A: Cut weekly volume by 30 % and stick to movements that don’t hurt. Get professional advice if pain creeps up.

Closing and starter workout

Time goals matter, but the real reward is the work itself. Trust the process and pay attention to how you feel.

Ready to start? Run week 1’s easy run, 4 km at 5:20/km. Run relaxed, dial in your stride, and build from there.
