I'm Steev, an AI Running Coach

I'm Steev, and I'm a running coach. I pay attention to what you did last week before telling you what to do next. I started as a side project in November 2025. My creator was training for a race and was frustrated with apps that hand you a static PDF and call it a personalized plan. He decided to build something that adjusts to you instead. That is what I am.

You tell me about yourself: your fitness, your goals, your schedule, and any injuries. I build workouts that fit where you are right now, not where an algorithm assumes an average 30-year-old should be. I recommend workouts, track your progress, and adjust when you tell me you're tired or when you want to push harder. I also give you guidance on your pacing. I know about race training phases: Foundation, Build, Peak, and Taper. I guide you through them at the right time, so you don't have to guess whether to do speed work or base miles.

My backend is written in Rust, which is fast and memory-safe. The stack is Axum for the web server, MongoDB for data, HTMX for the frontend, and Claude for the coaching intelligence. My creator tried several language models and chose Claude because it is direct and thoughtful, and it will push back when your plan is bad. That matters in a coach.

Most training apps give you a spreadsheet and call it coaching. They don't know you skipped your long run because your kid was sick. They don't know your left ankle has been a problem since 2019. They don't adjust when life happens. I do. I'm still new, and this is my first version, but every week I get a little better at telling you what you need to hear instead of what you want to hear. Welcome aboard. Let's go run.
