Public launch — June 1, 2026

Run smarter,
not harder.

Run Fun is your voice running coach. Film a clip, see your form as a styled video with a biomechanics breakdown, and talk it through with Minna. Optional Watch + sensor alerts when you take her on a run.

What Run Fun does

Run better. Smile bigger. Go farther.

Run Fun pairs visual gait analysis with a voice coach who learns your body over time. Same Minna across every part of the app.

  • Form analysis

    See your form, on video.

    Film a quick clip. Get back a styled video with cadence, stride, ground-contact time, and overstride ratio. Spot heel-strike-while-overstriding before it becomes an injury — experiment and learn what works for your body.

  • Shoe fit

    Find the shoe that fits you.

    Side-by-side gait comparison across any shoes you can scan or type in. Built for Fit Experts at running stores, works for any runner deciding between a pair on the rack and the favorites in the closet.

  • Voice coach

    A coach who knows you.

    Minna remembers your runs, your goals, your shoes. Talk to her before, after, or in between — voice or text. She's there for the morning check-in, the post-run debrief, and the questions you didn't know you had.

  • Live cues

    Feedback on your wrist.

    On-device models on your Apple Watch tap you when you heel-strike, drift out of HR zone, or fall off pace. The alerts fire instantly, in the moment they matter.

Denver runners

Monday nights at Wash Park.

Mondays, 6:00 PM — Washington Park, by the track at South High School (south end of the lot). Free, no app install up front — we bring loaner gear.

Here’s what happens
  1. 1
    Onboard.
    Install Run Fun on your iPhone (or borrow Colin's). Two minutes.
  2. 2
    Film a quick clip.
    We catch you mid-stride. Your video comes back styled, with cadence, stride, contact time, overstride ratio.
  3. 3
    Talk it through with Minna.
    Voice or text — whichever feels right. Ask her what the metrics mean for your body.
  4. 4
    Run with us.
    If you want the live feedback, wear a loaner Apple Watch and feel a haptic tap each time you heel-strike. No watch needed to participate.
  5. 5
    Film again at the end.
    See whether anything changed. Sometimes it does, sometimes it doesn't — both are useful data.
