Everything you need to run a sub-3:30 marathon: the exact pace, kilometre-by-kilometre splits, pacing strategy, and the training behind it.
To finish in 3:29:59 or faster you must average 8:00 per mile or 4:58 per kilometre for the full 26.2 miles (42.195 km), reaching halfway in about 1:44:59. Target 7:56 per mile / 4:56 per km in training to build a buffer for water stations, hills and congestion.
Even splits at 4:58/km. Need another finish time? Use the full pace chart.
An even split means holding 4:58/km from start to finish. A negative split means running the second half slightly faster than the first — for example passing halfway a minute behind even pace and closing it down in the final kilometres.
The most common way runners miss a time barrier isn't fitness — it's running the first third of the race slightly too fast and paying for it at the end.
Sub-3:30 is a strong club-runner goal, well ahead of the average finish time and close to Boston qualifying standards for many older age groups. Consistent training at 55–80 km per week is typical.

A typical sub-3:30 marathon build takes 16–18 weeks, with long runs building to 30–35 km, a weekly session at or near goal pace, and a recent half marathon around 1:38–1:41 as a fitness check.
To finish strictly under 3:30:00 (that is, 3:29:59 or faster), hold 4:58 per km or 8:00 per mile or quicker. These paces are rounded down to the second, so holding them exactly gets you under the line.

Finish in 3:29:34 — 0:25 under Sub-3:30.

You need to average 8:00 per mile or 4:58 per kilometre. Training at around 7:55 per mile (4:55 per km) gives you a buffer for race-day delays.
Yes. A sub-3:30 marathon is well faster than the average finish time and usually puts you in roughly the top fifth of a big-city marathon field.
A recent half marathon of around 1:38–1:41 is a common benchmark indicating you have the speed for sub-3:30.
Even pacing puts you through halfway in about 1:45:00. Stay close to that and resist running faster in the opening miles.
Most runners targeting sub-3:30 peak at roughly 35–50 miles (55–80 km) per week, with a long run of 18–22 miles.
It depends on age and gender. Sub-3:30 beats the men's standard from age 45 and the women's standard for ages 18–34 (3:25 is the women's 18–34 standard, so aim a little faster there).
