How to Use This Half Marathon Pace Chart
- Pick a realistic goal finish time based on recent race performances or tune-up 10K times.
- Read across the row to see your required pace per kilometer and key split times (5K, 10K, 15K, 20K).
- Memorize 2–3 checkpoints — the 10K split is the best “am I on pace?” marker, and the 15K split tells you whether to push or hold.
- Aim for a small negative split. The goal is to run the second half 30–60 seconds faster than the first half.
What Is a Good Half Marathon Time?
A “good” half marathon time depends heavily on age, sex, and training history. As rough recreational-runner benchmarks:
- Beginner: 2:15–2:45 (6:25–7:50 per km)
- Intermediate: 1:45–2:15 (5:00–6:25 per km)
- Advanced: 1:25–1:45 (4:00–5:00 per km)
- Elite: Sub-1:10 (under 3:20 per km)
Half Marathon Pacing Strategy
Most first-time half marathoners go out too hard in the first 5 km and pay for it after 15 km. The best race-day strategy for 13.1 miles is a slight negative split — hold goal pace or 3–5 seconds/km slower for the first 10 km, then settle into goal pace for 10–15 km, then push whatever you have left from 18 km to the finish.

Half Marathon Pace Chart (KM) FAQs
What pace do I need to run a sub-2 hour half marathon in km?
To break 2 hours in a half marathon you need to average 5:41 per kilometer (or 9:09 per mile). Key splits: 28:28 at 5K, 56:55 at 10K, 1:25:23 at 15K, and 1:53:50 at 20K.
What pace is a sub-1:45 half marathon per km?
1:45 requires 4:59 per kilometer (8:01 per mile). Check your splits: 24:55 at 5K, 49:49 at 10K, 1:14:44 at 15K, 1:39:38 at 20K.
How do I convert my half marathon mile pace to kilometer pace?
Multiply your per-mile pace by 0.6214 to get per-kilometer pace. For example, 9:00 per mile × 0.6214 = 5:35 per kilometer. This chart does the conversion automatically for every finish time.
Should I run even splits or negative splits in a half marathon?
Negative splits produce faster finish times for most runners. Aim to run the second half 30–60 seconds faster than the first half by holding back slightly for the first 10 km, then gradually building effort through the back half.
How accurate is a half marathon pace chart?
The chart assumes perfectly even pacing on a flat, well-measured course. Add 5–15 seconds per kilometer to your target pace for hilly or windy courses, and remember that GPS watches can over-report distance by 1–3% — trust the race course markers, not your watch.
