An 8-Week Strength Plan to Chase a parkrun PB

You won't turn a raw beginner into an elite in eight weeks, but for most club and recreational runners, eight weeks is genuinely enough time to see a strength-driven improvement in a 5K time — provided the running and strength work are structured sensibly together. The goal of this plan isn't to overhaul your training; it's to layer targeted strength work onto your existing running to sharpen power, running economy and late-race resilience — exactly the qualities that decide a close parkrun finish.

This plan assumes you're already running 2–4 times a week and are free of any current injury. If you're carrying a niggle, sort that first — see our piece on runner's knee and ITB pain.

Focus on establishing good technique on the key lifts before adding heavy load.

• 2 sessions a week, 30 minutes each
• Squat (or goblet squat) — 3 sets of 8
• Romanian deadlift — 3 sets of 8
• Single-leg step-up — 2 sets of 8 per leg
• Calf raise — 2 sets of 12
• Keep loads moderate — this phase is about movement quality, not maximal effort

Increase load and drop reps slightly to shift the emphasis toward maximal strength and power.

• 2 sessions a week
• Squat — 4 sets of 5, heavier than weeks 1–2
• Romanian deadlift — 3 sets of 6
• Bulgarian split squat — 3 sets of 6 per leg
• Calf raise (straight and bent-knee) — 3 sets of 10
• Add one short explosive element each session — e.g. 3 sets of 5 pogo hops or low box jumps, focusing on quick ground contact

This is where strength starts converting to speed. Sessions get slightly shorter but stay intense.

• 2 sessions a week, 25–30 minutes
• Squat — 3 sets of 3–4, heavy
• Single-leg Romanian deadlift — 3 sets of 6 per leg
• Explosive step-ups or box jumps — 3 sets of 5
• Reduce total accessory volume — this is about quality over fatigue
• Make sure your hardest running sessions (intervals, tempo) are getting priority in the week — strength work should never compromise these

• One short strength session early in the week — light load, low volume, just enough to stay "switched on"
• No new heavy lifting close to race day
• Prioritise sleep, easy running and confidence over any last-minute training changes
• On parkrun morning: a proper dynamic warm-up (leg swings, lunges, strides) matters more than anything you could add in the gym at this point
