Who this plan is for
- ✓You've run a half marathon between 2:05 and 2:20 and know you have more in you
- ✓You can run 8–10 km comfortably at an easy pace
- ✓You're frustrated that free plans gave you numbers but no understanding
- ✓You want a session-by-session plan that fits 3, 4, 5 or 6 running days
- ✓You're prepared to run some sessions that are genuinely uncomfortable — and want to know exactly why
- ✓You train around a full schedule — job, family, life — and need a plan that accounts for that
What your training actually looks like
Every session in the plan looks like this — with a plain-English reason, not just a pace. Here is a representative week from the middle of the plan.
💡 Week 7 is where sub-2 hour races are won or lost in training. The 800m repeats force your body to run 20–25 seconds per min/km faster than goal pace — that discomfort is precisely the point. When race day arrives, goal pace will feel controlled by comparison. The Saturday long run's final 3 km at goal pace rehearses race-day feel without the full physiological cost of a race.
The four phases
Base phase (weeks 1–3)
Establish a mileage base at genuinely easy pace. Three to five runs per week, long run building from 12 to 16 km. The goal is consistency without stress.
Strength phase (weeks 4–6)
Weekly tempo runs lift your lactate threshold — the pace you can hold for an hour before the wheels fall off. Long runs extend to 17 km with the final kilometre at goal pace.
Speed phase (weeks 7–9)
800m and 1 km repeats at faster-than-goal pace teach your body what controlled discomfort feels like. Long runs now end with 3–4 km at 5:41 min/km (goal pace).
Taper phase (weeks 10–12)
Volume reduces by 35–40%. You keep one quality session per week, shorten the long run, and arrive at race day with absorbed fitness and fresh legs.

Build my Sub 2:00 Plan →Frequently asked questions
I've run 2:08 twice and can't seem to break 2:10. What's missing?
The most common cause is running easy runs too fast and quality sessions not fast enough — you end up in a 'grey zone' where nothing improves. A sub-2 hour plan needs genuine easy days (conversational pace, 6:30–7:00 min/km for most runners at this level) and genuinely hard interval sessions. If both feel medium-hard, that's the problem.
What is goal pace for sub 2 hours?
To finish in 1:59:59, you need to average 5:41 min/km (9:09 min/mi). Most runners aiming sub-2 should target 5:38–5:40 min/km in training to build a small buffer. Your easy runs will be significantly slower — around 6:30–7:00 min/km depending on your current fitness.
How many weeks of base fitness do I need before starting this plan?
You should be able to run 10 km comfortably before week 1. If that's not yet possible, spend 4–6 weeks building to it with three easy runs per week. Starting the plan before you have that base usually results in injury in weeks 4–6 when the training load increases.
Can I run sub 2 hours on 3 days per week?
Yes, but it requires the three runs to be the right three: a long run (building to 18–20 km), one quality session (alternating tempo and speed weeks), and one easy run. Skipping the quality session and replacing it with a third easy run will not produce enough fitness improvement to break 2 hours for most runners.
What should I do if I miss a run in my sub-2 training?
In the base phase, missed easy runs are fine to skip — weekly consistency over 12 weeks matters more than individual sessions. In the strength and speed phases, protect the quality sessions (tempo, intervals) above all else — these are where sub-2 fitness is built. Missed an interval session? Reschedule within 48 hours, or drop it entirely — never double up. Missed the long run? Reschedule within 3 days. Missed a full week? Drop back one week and continue.
