Week-by-week overview
Weeks 1–4
Build
Threshold and race-pace work land on top of the base. Long run stretches toward its peak.
Weeks 5–6
Peak
Highest quality + highest fatigue. Race-specific sessions, then a down week before taper.
Weeks 7–8
Taper
Volume drops 40–60%. Keep a little intensity so you stay sharp, then race.
| Wk | Phase | Focus | Volume |
|---|---|---|---|
| 1 | build | sub-25 specific | 38 km |
| 2 | build | sub-25 specific | 38 km |
| 3 | build | sub-25 specific | 38 km |
| 4 | build | sub-25 specific | 38 km |
| 5 | peak | Peak specific load | 40 km |
| 6 | peak | Controlled down week | 40 km |
| 7 | taper | Taper — short quality | 22 km |
| 8 | taper | Race week | 17 km |
Sample week 5
Peak specific load · 40 km
Week 5 (peak): keep 6:15/km honestly easy. Quality lives at 5:00/km. If the long run feels heavy, cut 10% — don't add a day.

Who this plan is for
It's for someone who already finishes the distance and now wants sub-25 (25:00 on the clock, 5:00 /km). Catalog level: intermediate. If your current mark is more than ~12% off that goal, the personalized engine lengthens the block or eases quality paces — this preview uses the goal as the anchor.
How the weeks are periodized
Weeks 1–4: Build — Threshold and race-pace work land on top of the base. Long run stretches toward its peak. Weeks 5–6: Peak — Highest quality + highest fatigue. Race-specific sessions, then a down week before taper. Weeks 7–8: Taper — Volume drops 40–60%. Keep a little intensity so you stay sharp, then race. Volume doesn't climb in a straight line: each phase has its own wave, plus a down week before taper. Peak load 40 km. No full base phase: aerobic fitness is assumed to already be there.
Intervals, tempo and easy running
Quality A: intervals at 5:00 /km. Quality B (unless you're a beginner): tempo at 5:13 /km. Long run 14 km at long-run pace, not race pace. The classic 5K mistake is running the easy days at 5:00 /km; here easy is anchored to 6:15 /km.
5K: economy and recovery
The 5K is short; the mistake is training every day as if it were short. 4 days, with easy running at 6:15 /km so the intervals at 5:00 /km are actually fast. Long warm-up on quality day (12–15 min). The 14 km long run keeps the aerobic base that holds a 5 km effort together.
From this preview to a plan that's yours
The preview is anchored to “8-Week Sub-25 5K Plan”: 4 days, 40 km, 5:00 /km. At signup Peaking preloads distance (5K), 8 weeks and a sub-25 goal. The live engine then asks for PBs, available days and constraints, and regenerates whole weeks — not a static PDF. The CTA below opens registration with those fields and this page's UTMs.

Start freeFrequently asked questions
Is this 8-week sub-25 5K a generic plan?+
The overview and week 5 come from Peaking's periodization composer (same phases and session types as an in-app plan). It's persisted per slug — it doesn't change on every visit. The paid plan personalizes from your PBs and real days.
How many kilometres / hours per week does it peak at?+
Peak 40 km, key long session 14 km, 4 days. Base weeks sit well below that; the taper (Weeks 7–8) cuts volume and keeps short quality.
What pace should I use if my mark isn't 25:00?+
This preview anchors race to 5:00 /km, easy to 6:15 /km and threshold to 5:13 /km (sub-25 goal). In the app, paces come from your PBs or a Riegel predictor — don't copy these splits if your current 10K sits at a different level.
Can I skip days or squeeze this into fewer than 8 weeks?+
Skip an easy day, never the long run or both quality sessions in the same week. Compressing 8 → 8 often works if the base is already there; the hub lists other durations for this 5K.
How do I go from this page to a plan generated for me?+
Start free preloads 5K, 8 weeks and sub-25. You finish onboarding (sports, PBs, days) and the engine builds the full plan. This URL stays as the SEO reference; your plan lives on the dashboard.
