02 How it works

  1. Step 01

    Map the course

    Create your runner’s page and mark the moments — the start, the climbs, the wall.

  2. Step 02

    The crew records

    Family and friends each pick a moment and leave a short voice memo. No app, no account.

  3. Step 03

    Each mile unlocks

    On race day every memo opens at its own mile. One voice, exactly where it’s needed.

The moments

A course isn’t hard everywhere. It’s hard in a few places — and somebody who loves your runner should be standing at each one.

  • KM 0Gun

    The start

    Nerves at the line, shoes double-knotted, months of training behind them. The first voice says: you did the work. Go.

  • 21.1Split

    Halfway

    The crowd thins and the middle miles go quiet. Someone they love fills the silence with exactly why they signed up.

  • ~35The hard part

    The Wall

    Where the race actually starts. Legs empty, doubt loud. This is the message that carries them home.

Every runner has a hardest mile. Nobody should meet it alone.

First race or fiftieth, five kilometres or a hundred — the wall finds everyone. High Notes puts the people who love them right there for it.

03 Voices, pinned to the miles

Everyone stands somewhere.

Each supporter picks a mile and their voice waits there. As your runner passes, the right one arrives — never all at once, never a second early.

04 Saved from race day

They keep every voice.

After the medal goes in a drawer, the memos stay. This one got a runner over the wall — it plays exactly like it did at kilometre 35.

“You’ve climbed harder than this. We’re all right here. Go get it.”

A 14-second voice memo from Mom, kept after race day.
