From Non‑Runner to Your First parkrun

A friendly, real‑world 8‑week plan with simple pacing, what to expect on the day, and confidence‑building tips

Jump to the 8‑week plan

If you can walk for half an hour and hold a conversation, you can train for a friendly 5K. This guide keeps the effort easy, uses short run–walk intervals, and shows you exactly what happens at parkrun so you arrive calm and ready.

01Mindset & Safety

Go easy to go far. Your easy pace lets you hold a conversation (the "talk test"). Aim for effort, not speed.

  • Progress, not perfection. Walk breaks are built into the plan—lots of experienced runners use them too.
  • Check in with your body. If you have health concerns or pain that changes your stride, talk to a professional first.
  • Consistency beats intensity. Three short sessions per week > one big hero run.

02Gear You Actually Need

  • Shoes: Comfortable, well‑fitting trainers—no need for fancy carbon plates.
  • Clothes: Weather‑appropriate layers you can move in.
  • Optional: Simple watch/phone for intervals, cap/sunnies, a drink for after.

03How the Training Works

  • Run‑walk method: Structured intervals so you never feel overwhelmed.
  • Easy effort: Keep breath controlled (RPE 3–4/10). If in doubt, slow down or extend the walk.
  • Strength (10–15 min, 2×/week): Bodyweight squats, glute bridges, calf raises, side planks.
  • Rest days: Non‑negotiable for adaptation.

048‑Week Beginner Plan

Every session: 5‑minute brisk walk to warm up → intervals → 5‑minute easy walk to cool down + light stretches. If a week feels tough, repeat it before moving on.

Week 1

8 × (Run 1 min • Walk 90 sec)

Week 2

6 × (Run 90 sec • Walk 2 min)

Week 3

5 × (Run 2 min • Walk 2 min)

Week 4

4 × (Run 3 min • Walk 2 min)

Week 5

3 × (Run 5 min • Walk 2 min)

Week 6

2 × (Run 8 min • Walk 3 min)

Week 7

Option A: Continuous easy jog 20–25 min
Option B: 12 min run • 2 min walk • 8–10 min run

Week 8 (Event Week)

Early‑week: 20–25 min easy jog or 10/1 run‑walk ×2
Mid‑week: 15–20 min very easy jog
Saturday: parkrun 5 km (start very easy; pick up gently after halfway if you feel good)

Already active? If you walk a lot or cycle/swim regularly, you can usually start at Week 3–4.

05Pacing Without Overthinking

  • Talk test: If you can't speak in full sentences, slow down.
  • Run‑walk ratios: On the day, try 3:1 (run 3 min, walk 1 min) or 90:30 (run 90 sec, walk 30 sec) to keep things smooth.

06What to Expect at parkrun

  • Free, friendly, weekly. Most events are Saturday mornings (check your local start time).
  • Register once, bring your barcode. Printed or digital—see your local event's guidance.
  • First‑timers' welcome: Short briefing covering the course and how it works.
  • You won't be last. There's a Tail Walker who finishes behind everyone and supports newcomers.
  • Timing: Cross the line, collect a token, scan with your barcode—results arrive later.

07Race‑Day Checklist

Light breakfast 2–3 hours before (keep it familiar).
Sip water, avoid chugging right at the start.
Arrive 15–20 minutes early for parking, loos, and the first‑timers' briefing.
Warm up: 5‑minute brisk walk + 3 × 20‑second easy jogs.
Line up near the back or middle to keep things relaxed.
Start slower than you feel you can; finish strong.

08If Something Niggles

  • Shins/ankles: Ease the pace; use quick, light steps. Add calf raises once pain‑free.
  • Knees: Strengthen glutes/quads (bridges, squats); keep strides short and posture tall.
  • Fatigue: Sleep more; keep easy days truly easy; don't stack hard sessions.

09After You Finish

  • Walk 5–10 minutes to cool down; drink water.
  • Snack with protein + carbs within 60–90 minutes.
  • Celebrate your first time—then set a feel‑good goal (e.g., "complete 4 parkruns in 6 weeks" or "run the first 3 km without a walk break").

10Frequently Asked Questions

Do I have to run the whole way?

No—run‑walk is encouraged. Many people use it long‑term.

What's a good first‑timer time?

Any time that gets you across the line smiling. Many first 5K times sit between 25–45+ minutes—every one is welcome.

Should I do a time trial first?

Not necessary. A relaxed 20–25‑minute jog in Week 7 is enough confidence boost.
