Whatever your goal, run with a plan.

A first 5K or a faster marathon. From the couch or from your last race. Pulsar builds the plan that gets you there — and every run in it tells you how far, how fast, and why.

Any goal gets its own plan.

Pick a goal in the app — a race, a distance, a time to beat, or just running without stopping. Pulsar builds the plan to it: the weeks, the runs, the rest days, all the way to the finish.

  • Start running
  • 5K
  • 10K
  • Half marathon
  • Marathon
  • A faster time
  • Back to running

It starts where you are.

Pulsar asks how you run today: how long you can go without stopping, how many days you have, your latest race if there is one. Can’t run nonstop yet? Week 1 is short runs with walks in between. Already running? It picks up your usual miles.

How long can you run without stopping?

An honest answer sets the right starting point — there’s no wrong one.

  • I can’t run nonstop yetI take walk breaks to keep going
  • A few minutesUp to ~5 minutes before I walk
  • 10–20 minutesI can keep a steady jog going
  • 30 minutes or moreI can run continuously

Every week, worked out.

How many runs, how long each one, which day is the long run, where you rest. A little more every week, a lighter week every fourth so your legs catch up, and an easier last stretch so you arrive fresh.

One plan from Pulsar, as the app built it: a 10K in ten weeks for a runner with a 25:40 5K and four days a week. Yours is built from your goal, your days and how you run today.

  11. Your goal

Every run says how far, how fast, and why.

The distance, the pace to hold, the heart-rate zone to stay in, and what the run is for — in plain words. Zone 2 means you can still talk. Tempo means short phrases, not full sentences. Most runs are easy on purpose: that’s how fitness builds without wearing you down.

Coach’s insightTap to ask

Keep your heart rate in Zone 1-2. You should be able to hold a conversation easily. If you’re breathing hard, slow down.

Your zones

  • Zone 1: RecoveryEasy enough to talk in full sentences. Moves blood, builds nothing — that’s the job.

    ≤ 135
  • Zone 2: AerobicWhere most of your running lives. This is the engine that carries a long run.

    136–148
  • Zone 3: TempoComfortably hard. Steady and sustainable — short phrases, not full sentences.

    149–161
  • Zone 4: ThresholdHard but repeatable. Trains you to hold a faster pace before it starts to unravel.

    162–174
  • Zone 5: AnaerobicShort, near-maximal reps. Raises your ceiling. You can’t hold it long — you’re not meant to.

Easy days easy. Hard days hard.

Twenty seconds too fast,
and Pulsar says so.

The plan rides along: your pace against the target, the next segment, when to walk, when you’re done — in your earbuds, only when there’s something to say. Start on Apple Watch and leave the phone at home.

The voice coach, in your earbuds: “Slow down, 20 seconds fast.”

Ask why. Get a straight answer.

After every run, Pulsar tells you what it meant, with your numbers. Between runs, ask it anything: why easy runs are so slow, what to eat before a long one, what Zone 2 should feel like.

Coach’s insight

3.4 mi easy, and you kept it easy.

Heart rate stayed in Zone 2 the whole way and your pace held steady — exactly what easy runs are for. Rest tomorrow; Thursday is the 400s.

PULSAR Coach

Why is my easy pace so slow?

Because easy runs do a different job. They build your engine — heart, lungs, legs — without leaving you tired for Thursday’s 400s. If you can talk in full sentences, you’re right where you should be.

Why Pulsar exists

I trained for three marathons alone.

Pulsar is the coach I wish I’d had.
