Best Training App for a Sub-1:30 Half Marathon in 2026

For a sub-1:30 half marathon, AthleteOS is our top pick. Runna is the best run-only alternative, and Garmin Coach is the best free one. The goal needs 4:16 per km (6:52 per mile) for 21.1 km, and most apps still hand you a trimmed marathon plan or a stretched 5K plan.

Here’s how the five stack up, why the goal is a speed problem and not just a mileage problem, and where each app falls short.

Which app wins for which runner

• You want a plan built around your threshold pace: AthleteOS (ranked #1 below).
• You only run and want polished workouts: Runna (#2).
• You own a Garmin and want free: Garmin Coach (#3).
• You already have a coach or a bought plan: TrainingPeaks (#4) or Final Surge (#5).

What a sub-1:30 half marathon actually demands

Ninety minutes over 21.0975 km works out to 4:16 per km, or 14.06 km/h. In short: you hold a hard, steady pace for an hour and a half.

A 2020 study in Frontiers in Physiology measured speed at lactate threshold in 75 runners. That’s the fastest speed you can hold before fatigue builds quickly. Recreational runners averaged 12.1 km/h. National-level runners averaged 14.4 km/h. Elite runners hit 16.5 km/h.

In short: 1:30 pace sits just under the national-level threshold. You’re not training for an easy jog. You’re training your threshold up to the pace you want to race at.

The same study found something useful. Your maximal aerobic speed, the top speed your engine can sustain, tracked threshold speed at r=0.92. The percentage of VO2max at threshold barely differed between levels (about 82-85%). Translation: faster runners don’t sit higher on their ceiling. Their ceiling is higher.

Think of a car. Threshold is the speed you can cruise at without overheating. Raising the top speed of the engine lifts the cruising speed with it. So a sub-1:30 block needs real speed work on top of tempo runs, not tempo alone.

Why most “best running app” lists miss half marathoners

A half marathon is run near threshold. Older studies put recreational runners at about 79% of VO2max and sub-elite runners near 83%. Those samples were small, about 10 runners each. Still, the message is clear: this race is a tempo race.

A marathon plan scaled down gets the long run right and the intensity wrong. A 5K plan stretched up gets the intensity right and the endurance wrong. Neither one fits.

Think of it as cutting a suit pattern for a different body. You can pin and tuck, but the shoulders won’t sit right.

Plan listings back this up. A 12-week sub-1:30 plan on TrainingPeaks averages about 62 km a week by its listing. A Final Surge intermediate 12-week plan runs 60 to 72 km a week. A six-day Final Surge plan peaks near 50 miles (80 km). These are plan figures, not data from runners who actually ran 1:30. No one has published that survey.

Ramp rate: what the evidence does and doesn’t say

Many apps sell “load management.” Be careful here.

The acute:chronic workload ratio (ACWR) compares last week’s training with the past month’s. In a 2020 analysis, researchers simulated 1,000 seasons where load had no link to injury at all. Ratios outside 0.8-1.3 still looked linked to injury. In plain English: the number can look scary when nothing is wrong. A 2021 editorial shows the debate isn’t settled.

Running evidence is thin too. In 873 novice runners, those who raised weekly distance by more than 30% had more distance-related overuse injuries. A review reported about 1.6 times the injury rate for a 30% jump versus under 10%, with no difference for 10-24%. These runners were mostly beginners on low mileage, so the numbers don’t map neatly onto someone at 70 km a week.

Use ramp rate as a guardrail. It’s a speed bump, not a crystal ball.

Our ranking: best training app for a sub-1:30 half marathon

How we ranked these. We scored each app on five things: does it supply a half-specific plan, does it set pace from your fitness, does it adapt when you miss runs, how much does it cost, and how honest are its load numbers. We read vendor pages on October 19, 2026. We didn’t run head-to-head trials.

1. AthleteOS

AthleteOS builds a half-marathon-specific block from your current fitness and threshold pace. It doesn’t scale a marathon template down or a 5K template up. That gives a tempo-heavy sub-1:30 build a sensible volume and weekly ramp.

It costs $19.99 a month or $180 a year, with a 14-day trial and one free plan. Its weakness: it’s newer than TrainingPeaks and has fewer third-party plans to browse. For the full head-to-head on features, see AthleteOS vs Runna after the Strava acquisition.

2. Runna

Runna wins on polish. You choose a 12, 16 or 20-week half marathon plan with easy runs, long runs, hills, intervals, strides, tempo and threshold work. It syncs with Garmin, Apple Watch, Coros and Strava, and says plans adapt to your performance.

Its pricing page lists $19.99 a month or $119.99 a year with a 7-day trial. That page is dated 2025, so confirm today’s price. The public pages name no goal-time tiers like 1:30 and no weekly ramp logic. Strava owns Runna, and it’s run-only.

3. Garmin Coach

Garmin Coach is free. The half marathon is Garmin’s most advanced adaptive plan, running 12 to 26 weeks. It adjusts as you log runs and shows up as a widget on a paired watch.

The catch is the watch. You need a Garmin device. We couldn’t confirm how it handles a specific goal time, so check that in the app. We compare it more closely in AthleteOS vs Garmin Coach.

4. TrainingPeaks

TrainingPeaks Premium costs $19.95 a month or $134.99 a year, with a 14-day trial. It’s strong on analysis and planning tools. It does not include a coach or training plans. A 12-week sub-1:30 plan is a separate purchase, and its public page lists only the length and goal.

Best fit: you already have a coach, or you like a static plan and want deep charts.

5. Final Surge

The athlete tier is free, with stats and analysis on web, iOS and Android. It’s a delivery and logging tool. You still need a coach or a purchased plan to fill the calendar. Coach tiers run $19 and $39 a month. See AthleteOS vs Final Surge for details.

A mini case study: Dan, 34

Take a runner I’ll call Dan. He’s 34, runs 55 km a week, and just raced a 1:36 half. That’s 4:33 per km. To hit 1:30 he must shave about 17 seconds off every kilometer.

His old plan was a marathon template cut down. It gave him a long run of 24 km and slow miles, but almost no tempo work. That’s a mismatch. His race pace sits near threshold, and his plan hardly touched it.

A better build keeps his weekly volume near 60-65 km, adds a weekly threshold session and one short, fast speed session, and lifts weekly distance by modest steps. He’d also check progress with a tempo run at 4:20 per km before race week. This is an illustrative example, not a promise of a result.

Dan’s problem was the plan, not his effort.

Taper for a half marathon: keep the speed

A meta-analysis of 27 studies found the best taper lasted two weeks. Volume dropped 41-60%, while intensity and frequency stayed the same. That research covered runners, swimmers and cyclists, not just half marathoners. So it’s a guide, not a rule. In short: run less, but keep a few fast efforts.

Our full guide, how long to taper for a half marathon, covers 7, 10 and 14 day options. If you’re also racing shorter distances, see the best app for sub-20 5K and sub-40 10K.

How to choose

• Own a Garmin and want zero cost? Start with Garmin Coach.
• Run only, like polished workouts? Try Runna.
• Have a coach? Use TrainingPeaks or Final Surge to deliver the work.
• Want a plan built around your own threshold pace that adapts when work or sickness hits? Try AthleteOS free for a plan, or 14 days of paid.

No app will run the kilometers for you. The right one just stops you from training for the wrong race.
