Week-by-week overview
Weeks 1–6
Base
Aerobic volume, easy running, and a durable long run. Intensity stays mostly conversational.
Weeks 7–12
Build
Threshold and race-pace work land on top of the base. Long run stretches toward its peak.
Weeks 13–14
Peak
Highest quality + highest fatigue. Race-specific sessions, then a down week before taper.
Weeks 15–16
Taper
Volume drops 40–60%. Keep a little intensity so you stay sharp, then race.

Week 13 (peak): keep 6:31/km honestly easy. Quality lives at 5:41/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-2 hour (2:00:00 on the clock, 5:41 /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 1–6: Base — Aerobic volume, easy running, and a durable long run. Intensity stays mostly conversational. Weeks 7–12: Build — Threshold and race-pace work land on top of the base. Long run stretches toward its peak. Weeks 13–14: Peak — Highest quality + highest fatigue. Race-specific sessions, then a down week before taper. Weeks 15–16: 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 59 km. Week 13 (preview below) sits at peak quality.
Race pace inside the long run
The key long run reaches 20 km. For marathon/half, build and peak weeks finish a segment at 5:41 /km after easy kilometres at 6:31 /km. Weekly tempo lives near 5:26 /km. 4 days: if you miss one, you cut an easy run, not the long run.
Half marathon: threshold, not heroics
The half is decided near threshold (5:26 /km), not VO2 max. That's why there's more tempo and race pace (5:41 /km) than 400s. Fueling: one gel usually covers it; the error is going out at 10K pace. The 20 km long run teaches you to still be standing on Sunday, not to simulate the whole race every Saturday.
From this preview to a plan that's yours
The preview is anchored to “Sub-2 Hour Half Marathon Plan”: 4 days, 59 km, 5:41 /km. At signup Peaking preloads distance (half marathon), 16 weeks and a sub-2 hour 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 16-week sub-2 hour half marathon a generic plan?+
The overview and week 13 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 59 km, key long session 20 km, 4 days. Base weeks sit well below that; the taper (Weeks 15–16) cuts volume and keeps short quality.
What pace should I use if my mark isn't 2:00:00?+
This preview anchors race to 5:41 /km, easy to 6:31 /km and threshold to 5:26 /km (sub-2 hour 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 16 weeks?+
Skip an easy day, never the long run or both quality sessions in the same week. Compressing 16 → 12 often works if the base is already there; the hub lists other durations for this half marathon.
How do I go from this page to a plan generated for me?+
Start free preloads half marathon, 16 weeks and sub-2 hour. 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.
