Who this plan is for
- ✓You've run a half marathon between 2:12 and 2:22 and are ready for a structured step forward
- ✓Your comfortable easy run pace is around 7:05–7:50/km (11:24–12:37/mi)
- ✓You can run 10–11 km comfortably and want a plan that builds distance and quality work progressively
- ✓You train 3–5 days per week and need a plan that works around a real schedule
- ✓You want pacing guidance specific to your goal — not a one-size-fits-all free plan
- ✓You're ready to commit to one weekly quality session that will be genuinely uncomfortable
What your training actually looks like
Every session in the plan comes with a plain-English reason, not just a pace. Choose your schedule below to see what Week 1 looks like.
💡 Aerobic foundation: every run should be conversational this week. Easy runs are doing real work — mitochondrial density, fat oxidation, connective tissue conditioning. Miss a session? Skip it and move on.

Build my Sub 2:10 Plan plan →The four phases
Base phase (weeks 1–3)
Build aerobic base with easy running 3–5 days per week. Long run grows from 11 to 14 km. No formal quality work — the easy running is doing real physiological work.
Strength phase (weeks 4–6)
Weekly threshold tempo of 3–5 km at 5:41–5:47/km. Long run reaches 15–16 km. Everything else in the week supports the tempo session.
Speed phase (weeks 7–9)
400m and 600m intervals at 5:16–5:26/km add VO₂max training. Long run peaks at 17–18 km with optional final kilometre at goal pace.
Taper phase (weeks 10–12)
Volume drops 30–38%. Intensity maintained in shortened quality sessions. Fresh legs beat last-minute fitness every time.

Build my Sub 2:10 Plan →Frequently asked questions
What is goal pace for sub 2:10?
To finish in 2:09:59, you need to average 6:09/km (9:55/mi). Threshold tempo runs sit at 5:41–5:47/km (9:10–9:19/mi). Easy runs should be 7:10–7:55/km (11:32–12:44/mi) — meaningfully slower than quality sessions, so you arrive at tempo days fresh.
I've run 2:17 twice. Can I jump to sub-2:10 in 12 weeks?
A 7-minute improvement over 12 structured weeks is realistic if you train consistently and run quality sessions at the right intensity. Runners who plateau at 2:15–2:20 typically run everything at a medium-hard effort — too hard for easy runs, not hard enough for quality sessions. Polarising the two is the key adjustment.
What should my easy runs feel like?
Fully conversational — you should be able to speak in complete sentences without pausing for breath. At 7:10–7:55/km (11:32–12:44/mi) for this target, most runners feel they're going embarrassingly slowly. That's correct. Easy runs at this pace allow the quality sessions to actually be quality.
How many weeks of base do I need before starting?
You should be able to run 10 km without stopping before week 1. If that's not yet comfortable, spend 3–4 weeks with three easy runs per week, gradually extending the longest run to 10 km. Starting the plan with less than that base usually leads to injury in weeks 4–6 when training load increases.
