What is Half Marathon Strength?
This 12-week strength plan is designed to run alongside any half-marathon training schedule. Two strength sessions per week, sequenced to peak alongside your fitness and taper before race week.
The plan has three phases: Build (weeks 1-6, heavier strength emphasis), Integrate (weeks 7-10, shift to maintenance as mileage peaks), and Taper (weeks 11-12, lighter volume to fresh legs for race day). Each phase keeps the same movement patterns but adjusts load and intensity.
Research on half-marathon runners specifically shows that 12+ weeks of consistent strength training improves race times by 2-6%. For a 2:00 half-marathoner, that's 2-7 minutes faster — more than any single workout can deliver.
Best For
- + Runners training for a half-marathon in 10–14 weeks
- + Returning runners wanting injury resilience
- + Intermediate runners who plateaued on pace
- + Anyone doing Couch-to-Half-Marathon
Not For
- − Runners with under 3 months of consistent running
- − Anyone actively injured (rehab first)
- − Pure sprinters or 5K-focused runners (different priorities)
Program Structure
Phase 1 — Build (Weeks 1–6, 2x/week)
Heavier strength work while mileage is moderate
- Session A: Squat 4×5, Bench press 3×8, Bulgarian split squat 3×8/leg, Plank 3×60 sec
- Session B: Deadlift 3×5, Pull-ups 3×8, RDL 3×8, Single-leg RDL 3×8/leg, Face pulls 3×12
Phase 2 — Integrate (Weeks 7–10, 2x/week)
Maintain strength as mileage peaks
- Session A: Squat 3×5 at 80%, Bench press 3×6, Split squat 2×8/leg, Plank 2×60 sec
- Session B: Deadlift 2×5 at 80%, Pull-ups 2×8, RDL 2×8, Face pulls 2×12
Phase 3 — Taper (Weeks 11–12, 1x/week)
Fresh legs for race day
- Week 11: Session A only — Squat 2×5 at 60%, Bench 2×5, light core
- Week 12 (race week): Optional 20-min mobility + activation only. No heavy lifting
How to Progress
In Phase 1, progress load on compounds normally (add 5 lbs upper / 10 lbs lower when you hit reps). In Phase 2, hold weights steady — focus on maintaining strength, not building it. In Phase 3, cut volume by 50%+ to ensure fresh legs for race day.
Pros
- + Demonstrably improves half-marathon pace by 2–6%
- + Reduces injury rate during peak mileage weeks
- + Only 2 sessions per week, tapering to 1
- + Periodized to peak on race day
Cons
- − Requires coordinating strength and running schedules
- − Plan assumes you have a half-marathon running plan to pair it with
- − Not a standalone training plan (running happens separately)

Frequently Asked Questions
Does strength training help half-marathon times?
Yes. Peer-reviewed research on half-marathon runners shows consistent 2-6% pace improvements over 12+ weeks of strength training, compared to running-only control groups. The effect comes from better running economy and fewer injuries over the training block.
How many days of strength training during half-marathon prep?
Two sessions per week is the sweet spot. One session is suboptimal; three is too much for most runners who are also hitting 20+ weekly miles. The plan drops to one session in the taper phase (last 2 weeks).
Should I lift the day before a long run?
Avoid it during peak training blocks. Heavy lifting 24 hours before your long run compromises run quality. Schedule strength on your easy-run days or rest days — not adjacent to your long run or tempo days.
What lifts matter most for half-marathon runners?
Compound lifts: squat, deadlift, bench press, pull-ups, plus single-leg work (Bulgarian split squat, single-leg RDL). These hit the movements that transfer most directly to running economy and injury prevention. Bodybuilding isolation is optional.
Should I keep lifting after my half-marathon?
Absolutely. The goal isn't to lift just for the race — it's to lift for life. After the race, take a recovery week, then return to 2x/week strength work year-round for continued running health.
