The story

A lifelong athlete, back on the bike after 18 years.

I got in the pool at three and started running and playing hockey at six — and never really stopped. Twenty-four-plus years of running, three decades of swimming, and a hockey career that ran from AAA as a kid to the club team at Iowa built a base — and a set of legs — most people spend a lifetime chasing.

I've also been hurt since I was fifteen. The engine was never the problem; the body has been the project. A shoulder kept me off the bike for eighteen years until I had it repaired in summer 2024 and finally got back on — then a torn hip labrum went under the knife in February 2026. Every surgery, I rebuilt, and the lateral, explosive power from a life of hockey kept translating straight into watts.

So now, months out from hip surgery, I'm all in on one goal: my first triathlon. Off the course I'm the founder of Dump Days Ride Club, Warmup Running, SideRep and Lund Studio — I build fitness brands, communities and stories for a living. This isn't just a training log. It's a comeback, and I'm looking for the partners who want to help me tell it.

All in.
Hurt since 15.

Laguz · the water
Thirty-one years
in the water.

The pool came first. I started swimming at three — before I could really run, before a hockey stick, before anything. Three decades later it's still the most familiar place I train, and the one leg of the three I've never had to learn from scratch.

It's where the whole endurance story began, and it's the leg I worry about least. For Boulder, the work isn't fitness — it's turning pool yards into open-water rhythm: sighting, contact, and pacing across 1.2 miles in my strongest discipline.

Year one
on the bike.

Eighteen years off the bike, and back on it at thirty-four. The shock wasn't the fitness — it was how fast it came. A life of hockey built lateral, explosive power, and it's translating straight into watts.

It's the newest leg and the most fun I've had training in years — no streak to protect, no decades of history. Just a rediscovered love of going fast on two wheels, and the leg with the most room left to grow.

Twenty-eight years
on the road.

Running started at six and never stopped. Twenty-four-plus years without missing a day — not a training plan, a daily rite. It's the discipline the whole comeback is built on.

It's the leg I trust most, and the reason I started a club: Let's Go Run Club at Standley Lake, every Saturday. The road is where the grove keeps its rhythm.

Swim. Bike. Run.

One athlete, told through the three ages each sport entered my life. Each one stacked on the last — and now they meet at one start line.

My first sport and my oldest habit. Three decades of pool time means the water is the leg I worry about least — it's where the whole endurance story began.

The discipline that defines me. Running nearly every day for over two decades, and now the founder of a run club that meets at Standley Lake every Saturday.

Bike
After 18 years off

A shoulder injury kept me off the bike for eighteen years — until surgery let me ride again. Now I'm all in on a new aero race bike and an all-day e-road, and a life of hockey is making the power come fast.

The 70.3 is the perfect test for where I am: a 1.2-mile swim in my strongest sport, a 56-mile bike in my newest one, and a 13.1-mile run to finish on the legs I trust most.

Boulder is home turf — racing at altitude, in my own backyard, in front of my own community. The whole build, from first ride to finish line, is the story I'm documenting and sharing.

The line · of the grove
Old Norse — the sacred grove

Carter Luense descends from the line of Lundr, and everything here is drawn by the rule that shapes the grove itself: φ = 1.618, the Divinity Rule. Three sports, three decades, one bloodline — grown, not built.

ᚠ ᚢ ᚦ ᚨ ᚱ ᚲ ᚷ ᚹ ᛟ
  Niall of the Nine Hostages → Uí Néill → Maguire of Fermanagh → Flight of the Earls, 1607 → Wietmarschen → Lundr → Luense

Lundr — Old Norse for the sacred grove. The line runs from Niall of the Nine Hostages to here, and every proportion in this spiral is set by φ = 1.618, the Divinity Rule. The studio I build everything with.

Built with AI.
Building AI.

Off the course, Lund Studio is an AI house: councils that deliberate, rankers that score out of 100, a programming language written in runes. Everything on this page — the proportions, the type floor, the grove — was directed by me, built with Claude, and measured before it shipped.

Councils

The Council Builder

Assemble a council of AI seats from hundreds of frameworks and put your question to it. Every seat argues its discipline; the council answers.

Rankers

DÓMR

The skill ranker. Every Claude skill and open Agent Skill scored out of 100 on the Skill Scale, with the reasoning printed under the seal.

Rankers

Masteor

Who actually builds with AI. The practitioners board, ranked on the public record — and yes, I put myself on it.

Routing

Lundr.ai

One door, many models. Ask once; the model that should answer, answers.

Languages

Runescript

A programming language written in Elder Futhark, with its own compiler. Ancient script, modern machine.

Cards

AISKILLCARDS

AI skills, sold as cards. Makers forge and sell them beside the house shelf, and every card says exactly what is on the tin.
