A half marathon pace chart helps convert a goal time into a steady pace plan for 13.1 miles or 21.1 kilometers. The goal is to turn pace, speed, and split math into numbers you can use on a watch, treadmill, track, or race course.
Why Half Marathon Pace Matters
Half marathon pacing rewards patience because early overpacing can become expensive after the first hour.
A target pace should be sustainable, not just mathematically tied to a goal time.
Choosing a Goal Time
Use a recent 10K, previous half marathon, or current long-run fitness as context.
If endurance is the limiter, a race predictor may overestimate what is realistic.
Using the Chart
Convert the goal time into mile or kilometer pace, then plan checkpoints that account for terrain and aid stations.
Practice goal pace in workouts before relying on it on race day.
Method and Sources
How this page is checked
- Pace, speed, split, and chart pages use deterministic distance/time arithmetic.
- Pace is calculated as elapsed time divided by distance; speed is calculated as distance divided by elapsed time.
- Accuracy depends on the distance and time values entered or listed in the chart.
