Voice-led pace coaching

Be your
personal best.

Spread the pace

Peanut Butter puts two voices on your run. Drift under your aim pace and your arch-enemy gains ground. Hold it, and someone who loves you carries you to the PB.

“Slowing already? I'm 40 metres back.”

Two poles

One is chasing. One is cheering.

Distance is pace. Slow down and the arch-enemy's voice gets closer; hold your aim and the other voice takes over.

40 m behind and closing

Fires when your pace drops under your aim.

Arch-enemy voice
  • 0.4 km

    Oh, you're running now? Since when?

  • 1.2 km

    I'm gaining. You always did start too fast.

  • 2.0 km

    Nice split. Annoying. Keep it up and you lose me.

  • 3.1 km

    Fine. You escaped. This time.

Worried, proud, and asking about water.

Press play on a voice. Nothing bad will happen, probably.

Real ElevenLabs voices. Press play again for the next line — cloning someone who genuinely annoys you comes later.

See exactly what moved your pace.

Every prompt is marked on your post-run pace timeline. If a taunt or a word of encouragement changed your split, it shows.

    GPS watches your pace in real time and cues the right voice at the right metre.

    See what moved you

    Your pace timeline, every prompt marked, and the seconds you took off your PB.

Aim pace, set once
Aim pace, set once

Pick the pace that beats your PB and how often you want to hear about it. Everything else reacts to that number.

Two voices, one job
Two voices, one job

Drop off pace and your arch-enemy closes in. Hold it and someone who loves you talks you through the last kilometre.

Knows where you are
Knows where you are

Narration is location aware, so the hill, the bridge and the last corner all get their own line.

Proof, not vibes
Proof, not vibes

The post-run timeline marks every prompt against your pace, so you can see exactly what moved you.

Streaks that mean something

A streak counts only when you hold your aim pace. Slow weeks stay honest.
