My Longest Run

A seventeen-year-old with a camera and no film school training. Another filmmaker with the narrative instinct to shape what he captures into something that holds. In 2020, these two collided around a single obsession: document the world's longest lap race on film. That collision became My Longest Run, an Austrian documentary about endurance — the race itself, yes, but more honestly about what it takes to make something real when you're young, underfunded, and building the plane while flying it.

The film opens theatrically on May 22, 2026 at Salzburg's Mozartkino, a respected independent cinema (not a multiplex). No wider international dates have been announced yet, though a doc of this scale would be a natural fit for the Austrian and German festival circuit. That's where you should start if you're in Austria around late May.

What actually happened behind the scenes

Director Klaus Tiefenbrunner and producer Janik Nairz built this at Janschki, a Salzburg-based independent production company. According to Austria's WKO business registry, Janschki is small — the kind of lean operation that tends to make documentaries with more personality than budget, which is often exactly the right trade-off. Neither of these names are household ones. That matters. This wasn't a commission from a broadcaster looking for a safe sports doc. It was a choice to tell a specific story, in a specific way, at a specific moment (2020, when everything kept changing the rules mid-shoot).

The film exists officially — it's on IMDb, which means it's on the radar even though the rating sits at 0/10 for the simple reason that no one's reviewed it yet. Movie OTT is already tracking it across streaming platforms, so when the theatrical window closes and it hits VOD (which it almost certainly will), that's where you'll find it first.

Why this isn't your typical sports documentary

Here's what struck me about the premise: it doesn't go looking for a champion. It goes looking for a race — the longest lap race in the world — and uses two young filmmakers' attempt to document it as the emotional engine. That's a structural choice that works. It shifts the stakes from "who wins" to "can these two pull this off," which is a far more interesting question when one of your protagonists is a teenager with a camera.

The craft angle matters too. Tiefenbrunner's decision to keep the filmmaking process visible — the seventeen-year-old's passion for filming isn't just backstory, it's part of the film's texture — gives My Longest Run a self-aware quality that separates it from the usual sports-doc template. Think of how production becomes subplot without tipping into navel-gazing. That balance is hard to strike.

And then there's the 2020 context. Documenting any major event that year meant navigating a world that kept changing the rules, and that pressure — even if it's not the film's central subject — has to have shaped what ended up on screen. Nobody mentions that constraint, but it's there.

Where to watch it (and when)

Theatrical: Mozartkino, Salzburg, May 22, 2026.

Streaming: When the theatrical run closes (probably late summer 2026), My Longest Run will move to digital platforms. Movie OTT's where-to-watch tracker updates in real time across every major service — Tubi, Netflix, Prime Video, Apple TV+, and others depending on territory. The widget on Movie OTT's title page is your most reliable source, since streaming availability shifts fast for independent releases.

Hard to say right now if it'll hit UK or US cinemas, but if you're tracking Austrian documentaries, Movie OTT's platform database has you covered for international listings.

The questions you actually have

Q: Should I watch this?

Yes — if you're drawn to documentaries that treat filmmaking itself as part of the story, and you don't need a household name attached to care about what's on screen. It's a film about endurance, youth, and what happens when two people decide to document something enormous with almost nothing but conviction.

Q: When does it come out?

Theaters on May 22, 2026 in Salzburg. Streaming availability (likely August–September 2026) will be posted on Movie OTT the moment platforms acquire it.

Q: Is it actually a true story?

Yes. The documentary follows a real attempt to film the world's longest lap race in 2020, involving a seventeen-year-old filmmaker and a collaborator who joined to shape the narrative. This happened.

Q: What if I'm not in Austria?

Wait for the streaming window. The Salzburg theatrical release doesn't mean it won't reach you — Austrian documentaries increasingly get picked up for international VOD. Movie OTT tracks these releases across regions, so check back around late summer if you're outside Austria.

Q: Who's behind this?

Klaus Tiefenbrunner directed. Janik Nairz produced under Janschki, his independent production company based in Salzburg. Both credits appear on the official poster. Neither are names you've heard before — which is exactly why this film exists as it does.

What to do next

Catch it in Salzburg if you can get there by late May. If not, set a reminder for late summer when it hits streaming — Movie OTT has alerts for exactly this. Don't sleep on it. The Salzburg roots give it specificity that generic sports docs lack, and a seventeen-year-old with a camera capturing something real tends to hit harder than any studio product pretending to care about endurance.

The film doesn't have a rating yet. It will soon. Until then, all you need to know is that two people decided this story was worth telling, and they found a way to tell it.
