Sub-1:30 Half Marathon

Mile-by-mile splits for 1:30:00

The half marathon punishes early bravery less brutally than the marathon, but it still punishes it. The even-split table below holds 6:52 per mile for all 13.1 miles and passes halfway at 45:00 on the way to 1:30:00. Treat those numbers as a ceiling for the opening miles, not a target to beat.

The negative-split version opens at 6:56 per mile through halfway (45:27) and closes at 6:48. Over 13 miles that is a small, survivable debt to take on early and a large psychological win to collect late — you spend the last three miles passing people instead of being passed.

Even splits — 6:52 per mile

Even pacing: 6:52 per mile for all 13.1 miles, finishing in 1:30:00.

Slight negative split — 6:56 out, 6:48 home

One percent either side of even: 6:56 per mile through halfway (45:27), then 6:48 home. Same 1:30:00 finish. The mile that straddles halfway blends both paces.

Per kilometre — 4:16 per km

Even pacing in metric: 4:16 per kilometre across 21.1 km.

Are you ready for a sub-1:30 half marathon?

Equivalent times are computed from the rounded VDOT of 51, so the half marathon row lands within a few seconds of 1:30:00 rather than exactly on it. That is rounding, not a different prediction.

The table above is the price of admission. Holding 6:52 for 13.1 miles means you should already be capable of roughly a 19:36 5K or a 40:38 10K. A sub-1:30 half is not a distance problem for anyone who can run those times — it is a sustained-effort problem.

What makes this goal specific is how close race pace sits to threshold: 6:52 per mile against a threshold pace of 6:44. You will spend most of the race a few seconds either side of the line where lactate starts winning, which is why the work that moves this barrier is threshold work — repeated, boring, weekly. Runners who miss a sub-1:30 usually miss it in miles 9 through 11, and usually because the first three were run on adrenaline rather than to the plan.

Ninety minutes for a half marathon is the club-runner benchmark, and 6:52 per mile is what it costs. It is a satisfying number to chase because the maths is clean — seven-minute miles, near enough, for thirteen of them — and because it sits right at the edge of what threshold training reaches. The honest warning: at 6:52 against a threshold pace of 6:44, this race is run on the razor. There is no cruise phase. Runners who break ninety describe the last three miles the same way every time, and none of the descriptions are pleasant.

Enter a race you have actually run and this will tell you where you stand against the 51 VDOT a sub-1:30 half marathon requires — your score, the target, and the gap. Nothing is stored or sent anywhere.

Training paces for a sub-1:30 half marathon

These are day-one paces for a 51 VDOT — the fitness a sub-1:30 half marathon requires. They are a snapshot, not a season: as you get fitter every one of them should get faster, and training at last month's paces is how a good block goes stale.

Easy pace is a range rather than a point — Daniels defines it as 59–74% of VO₂max, which for this fitness runs from 7:45 to 9:17 per mile. The single easy figure below is the 70% value.
