Half marathon
How to plan for a half marathon personal best.
PBs come from consistent easy mileage, well-structured threshold and disciplined pacing on race day.
Mileage that matters
Aim for 4–5 runs a week with one long and one quality.
Race-specific work
Add half-marathon-pace segments inside long runs in weeks 7–10.
Taper sensibly
Two weeks of less volume, same intensity.
