Sub-1:30 is the half marathon line for advanced amateurs. The pace is 6:52 per mile for 13.1 miles. It's the step after sub-1:45 — a meaningful jump in pace (from 8:00 to 6:52, a 15% increase in speed) that requires real training. For runners chasing it, the satisfying part is that it's reachable on much less volume than marathon goal times.

This article covers what a sub-1:30 plan demands. For the broader picture, see the half marathon training plan guide. For the step below, see the sub-1:45 half plan.

The Honest Prerequisites

  • Recent 5K under 19:00. The VDOT math: a 19:00 5K predicts ~1:28 half. If your 5K is over 20:30, sub-1:30 is a stretch.
  • Recent 10K under 40:00. The most predictive single race. 40:00 10K = 1:29 half on Daniels' tables.
  • One half marathon completed. Pacing discipline at 6:52 takes experience.
  • Weekly mileage history of 30+ miles. Ramping from 20 to 50 mpw mid-cycle is risky.

Weekly Mileage Required

Most sub-1:30 half plans peak at 40-55 miles per week (64-88 km). Less than marathon training but more intensity-heavy.

  • 5 days per week minimum. Four days works if you've been running consistently.
  • Two quality sessions per week. One threshold/tempo, one VO2max.
  • Long run with half-marathon pace work. The signature long-run shape.
  • Recovery weeks every 3-4 weeks.

The Plan Structure

A typical sub-1:30 week in mid-build:

  • Monday: Easy 6 miles or rest
  • Tuesday: VO2max session. 5×1 km at 5K pace, or 6×800 m at 5K pace. 8-10 miles total.
  • Wednesday: Easy 6-7 miles
  • Thursday: Threshold workout. 4×1 mile at half marathon pace, or 25-30 min tempo. 9-11 miles total.
  • Friday: Easy 4-5 miles or rest
  • Saturday: Easy 4 miles
  • Sunday: Long run, 12-16 miles with half-marathon pace miles built in

Total: 42-50 miles. Two quality days, one long run. Higher intensity-to-volume ratio than marathon training.

Half-Marathon-Pace Workouts

The signature workout for sub-1:30 training is the sustained half-marathon pace effort. A progression:

  • Week 4: 10 miles with 4 at half marathon pace
  • Week 6: 12 miles with 6 at half marathon pace
  • Week 8: 13 miles with 7 at half marathon pace
  • Week 10: 2 × 5 miles at half marathon pace with 5-min jog between
  • Week 11: 15 miles with 10 at half marathon pace
  • Week 12: 14 miles with 8 at half marathon pace (race-week pre-race long)

The 2×5 mile workout in week 10 is the most-cited sub-1:30 dress rehearsal. If you can do it, the fitness is there.

Pacing Sub-1:30 on Race Day

The pace is 6:52 per mile. The half marathon allows slightly more aggressive pacing than the marathon because of the shorter duration.

  1. First mile in 6:55-7:00. Slightly slower than goal pace.
  2. Miles 2-10 at goal pace (6:52). Lock in. Most sub-1:30 races are won or lost in this section.
  3. Miles 11-13 at goal pace or slightly faster. If you've trained well, you have a kick in you.

Pick a flat, fast course for the goal attempt. Print a pace band — use the marathon pace band generator.

Common Sub-1:30 Mistakes

Going out at sub-1:25 pace. Common at this level. The energy at the start, the fresh legs, the cool weather all conspire. 6:30 for mile 1 ruins the second half.

Inadequate threshold volume. Sub-1:30 requires sustained threshold fitness. One tempo per week isn't enough. Two quality sessions per week, both partly threshold-flavored.

Treating it as marathon training in miniature. Sub-1:30 needs more intensity, less total volume. Higher quality-to-easy ratio than marathon plans.

Skipping the 2×5 mile dress rehearsal. It's the best indicator of race-day fitness.
