Find your crew, keep your streak, and train with the clubs in your corner. SideRep is the social layer for endurance athletes — the daily training loop, made social.
Clubs are the wedge. Retail reaches runners through their clubs. We're building the home base for everyone who trains on purpose.

One home base for your crew — group runs, RSVPs, streaks, and your people in a single place built to get them out the door.
Reach the runners who already train with you. Events, group runs, and drops land native in the app — not lost in a feed.
Plug into clubs and athletes directly. Show up where training actually happens — no ad auction, no middle layer.
Founding partners get me, personally. Build your page below and you're on the founding list — I'll work with the first clubs and businesses by hand to take it live, and we'll shape this exact flow together for everyone who comes after.
So we can set your page up with you and hand you the keys.
You're on the founding list. I'll be in touch personally to take it live — and we'll build the flow around how you actually run.
SideRep is a production-grade app, in preview today. It turns the daily act of training — the run, the ride, the swim, the lift — into something social: a streak you keep, props you trade, gear you track, clubs you belong to.
The strategy is simple. Clubs are the wedge. Run clubs already hold the runners; SideRep gives them the tools to run their chapters, events, and members across cities. Retail is the bridge — shops, insole brands, and gear makers reach those runners through the clubs they already trust.
"Show up. Keep the streak. Never break the chain."
SideRep is built product-first and founder-led. The app is real and in people's hands before the pitch — we'd rather show than tell.
SideRep is built by Lund Studio — an IP-house venture studio in Colorado. Lund Studio holds the Divinity Rule: a design system built on φ, the golden ratio (1.618), and its application to how software and AI get made.
That’s how a product this large came together this fast. One rule governs every surface — the proportion of a card, the pace of a streak, the way a screen comes alive. When the whole thing composes from a single system, it moves at a different speed.
The principle names are open. How each one is applied lives behind the work — the Divinity Rule, held by the Luense Family Perpetual Equity Trust.
From the feed you wake up to, to the gear on your feet — every part of the training loop, in one app.
Your feed, your rules. Filter by sport, crew, or club, drop props and toasts, and mute the noise.
The chapters worth keeping. A sacred archive for your milestones — private, witnessed, or sealed forever, with a Stillpoint reading mode.
Find your people. Vibe-based matching pairs you with crews, clubs, and partners who run your pace, your hours, your way.
Pin and reorder the tabs you actually use, then set a Solar theme that tints the whole app — and even shapes your coach.
Merch & drops. SideRep and club-exclusive gear, limited kits, and member-only drops.
The second-hand market. Give your gear a second life — buy and sell pre-loved shoes and kit, runner to runner.
Plus Clubs, race-day live tracking, and dashboards for businesses and brands — with more landing all the time.
Routes, pace, segments, and a real social feed — rebuilt on Apple Maps with Burn Trail. Strava's recent map and social changes haven't landed; SideRep is built the way tracking should work — for every sport and every level, from a first 5K to elite training blocks.
Crisp, fast, accurate maps — no muddy tiles, no clutter. Your routes look as good as they felt.
Your effort drawn on the map — heat where you pushed, the story of the run at a glance.
Props, crews, and clubs in the feed — built for your people, not an algorithm.
An aspen grove looks like a stand of separate trees. It isn’t. A whole grove is one organism — a single root system underground, every trunk fed from the same source, holding each other up through the winter. Lundr, the name behind our studio, is Old Norse for a sacred grove. That’s not decoration — it’s the model: a network that looks like individuals and lives like one root.
SideRep is that root system for runners — crews, clubs, and partners connected under the surface, so when one of you heads out into the cold, the whole stand keeps growing.
And it’s no accident we’re building it here. Colorado is a runner’s home: trails out every back door, more peaks above 14,000 feet than any other state on the horizon, mountain towns built around moving, and a culture that’s chased thin-air miles for generations. Come run where we’re from. If you’ve ever thought about it — this is a good place to live. Move to the Front Range, find your crew on day one, and never run alone again.
A few details computed the instant you opened this — on your device, just for you, gone when you leave. The kind of small, exact, slightly obsessive touches a product built for 2100 leaves lying around.
SideRep is built on one idea: a chain you don't break. So this knows what time it is where you are, and exactly how much of today is left to keep it lit.
Folded from a single number — the millisecond you showed up — into a sigil no hand drew and no one else will ever see.
Operators are how SideRep grows — city by city, club by club. These are the roles that build the network where the running actually happens. Hands-on, ownership-minded, and close to the community.
An operator is the person who owns SideRep in their corner of the map — one lead per market. Think of it like a local franchise built on relationships rather than real estate: you're the face of SideRep to the clubs, shops, and runners in your city.
You already know the morning crews, the Saturday long-run groups, the shop with the good treadmill. Your job is to bring them onto SideRep, help them actually use it, and grow the network from the ground up. We build and run the product; you build and run the community.
Own a market. Stand up the local chapter, recruit clubs, and grow the network on the ground in your city or region.

Every day you show up is a day the fire stays lit. SideRep turns the streak into something you can see, share, and never want to break. Keep the flame — that's the whole game.
Burn, don't break is the surface. Underneath it, every screen, streak, and spacing in SideRep is laid out on one ratio — φ = 1.618, the Divinity Rule. It opens with Heaven and closes with Earth: the going out, and the coming home.
The transcendent that opens the rule. In SideRep it's the run that hasn't happened yet — the ember you light when you head out the door. Reach, ascent, the chain extended one more day.
The transcendent that closes it. The return is where the streak is logged, the flame is fed, and the work becomes something witnessed and kept — in the Vault, for good. The loop that lets the next day begin.
The nine principle names are open. How each one is applied lives behind the work itself — the Divinity Rule, held by the Luense Family Perpetual Equity Trust.
Your streak is personal — your flames are shared. Run with the same crew or training partner and a flame grows between you. Keep showing up together and it climbs; let your sessions together slip and it cools. The streak, made social.
A crew flame burns as long as the group keeps its standing session. One shared run a week is all it takes to keep it lit — the whole crew sees it climb.
Every route has a keeper — the fastest time anyone in your circle has logged on it. Take the top spot and the route is yours until someone burns it down. Your local trails become a living leaderboard.
Hold a route 30 days straight and it becomes a Grove crown. Lose it and you'll get the alert the moment it's taken — so you can go take it back.
Drop into a challenge whenever you want one — most miles, longest streak, fastest 5K, most vert. Run solo or throw your whole crew in. Climb the board and stack up the heat.
Crew challenges pool everyone's miles into one total. Pull a few teammates out for a weekend long run and the whole crew climbs at once.
SideRep isn't built to be flipped. It's built to be handed down — a network meant to outlast the people who started it, the way the best run clubs already do. Drag the horizon and watch the streaks compound.
Some chain that's unbroken today will still be lit in 2100.
A founder's ambition — held in trust, not sold. Numbers shown are vision, not promises.

Social media that gets you out the door.
Every other app is built to keep you on the couch, scrolling. SideRep is built to get you outside — and to keep your people out there with you. The only number we ever want falling is time spent staring at the app.
Quick respect. Rare ceremony.
Someone in your crew just closed a long run. You send a prop for the work — or, when it’s a real milestone, you raise a toast. That’s the whole language: a fast nod for showing up, and a glass raised for the moments that matter.
Live · tap the reactionsRespect for the work nobody saw.
The 6 a.m. in the rain. The boring Tuesday miles. The streak day you almost skipped. Props are lightweight, specific, and earned — the everyday current that runs between people who train.
You raise a glass.
The PR. The first sub‑20. The comeback run after injury. The 365th day of a chain unbroken. Toasts are rarer and bigger — witnessed by your people and kept in your Vault for good.
Your people, not strangers
No influencers, no algorithmic randos. Your crew, your chain, your Saturday at the lake.
An algorithm with one job
Seven signals — pace, schedule, geography, goals — to match you with people who actually fit, and get you out the door.
Out, not in
Every nudge ends with you lacing up. Time on the app is the one metric we want to fall.
No ads, ever
One customer: the runner. One goal: your next session. Nothing in your feed is for sale.
The original sin of social media was serving advertisers instead of you. SideRep’s algorithm has one customer — you — and one goal: the next time you head out the door.
