The prototype is live at plan.getlecka.com.
I want to be clear about what it is before I explain what it does. It's not a product recommendation engine dressed up as a tool. I've seen those. They ask you three questions and serve you a cart. That's not what I was going for.
The thinking was: if you're a Lecka customer, or even just an endurance athlete thinking about race nutrition, what do you actually need to know? Your carbs per hour. Your sodium. Your fluid intake. Your caffeine if you use it. These are the variables that matter on race day, and most people don't have a clear number for any of them.
The planner takes your race information, your training data, your physical stats, and calculates a nutrition plan based on 27 research inputs. I spent a significant amount of time on the research side to make sure the formula was grounded in something real, not guesswork.
From there, you can select Lecka products to build your race-day plan. We're also working on a version where you can add competitor products — because most athletes don't fuel with a single brand, and pretending otherwise wouldn't be honest. The goal is a useful tool, not a conversion machine.
This is the fourth version I've built. The first attempt was about two and a half years ago, and the technology at the time made it clunky and frustrating to use. AI tooling has changed dramatically since then — building the logic is considerably easier now. What hasn't changed is the hard part: making it actually useful for a real person trying to figure out what to eat for a 100km race.
The prototype is live. It's free. It's a work in progress. If you use it, I'd genuinely like to know what you think.
