🏃‍♂️ From Sprinter to Developer

For years, I’ve been chasing faster times on the track — and learning the hard way that there aren’t many affordable tools to help sprinters like me analyze form, track progress, or plan smarter training.

So I decided to build one.

🎥 Watch: Why I Built SpeedTrackr

In this video, I explain the why behind SpeedTrackr — and how it blends my passion for sprinting with AI and coding.


💡 What Is SpeedTrackr?

SpeedTrackr is a web app for sprinters, coaches, and sports enthusiasts. It provides:

  • 🎯 AI-Powered Sprint Form Analysis using Kinogram-style pose detection
  • 🧠 Training Plan & Season Planner with smart periodization
  • 📖 Training Journal that includes weather and nutrition data
  • 🤝 Coach-Athlete Connect to get feedback
  • 📊 Performance Insights & Trends with beautiful visualizations

Built by a sprinter, for sprinters — no big sports tech budget needed.


🔍 The Problem I Wanted to Solve

  • No tools for athletes to self-analyze sprint form easily
  • Training data scattered across notes, spreadsheets, and memory
  • AI tools too expensive or not athlete-friendly
  • Lack of personalization in generic training plans

👨‍💻 How I Built It

  • Frontend: Next.js with React and Tailwind
  • Backend: Node.js with API routes
  • AI: Gemini 1.5 Flash + MediaPipe + custom analysis pipeline
  • Storage: Kinogram generation, S3, and DynamoDB for user data
  • Credits System: 1 free AI credit/week, additional via top-up

🌍 Who This Is For

  • 🏃 Solo sprinters without access to coaching
  • 🏋️‍♀️ Athletes who want to optimize based on weather, nutrition, and form
  • 📈 Coaches who want to track and analyze athlete progress
  • 💡 Techies who want to learn how to combine sport and software

📈 What’s Next?

I’m currently working on:

  • Google Fit + Nutrition tracking (inspired by HealthyfyMe)
  • Strava integration for cyclists and endurance runners
  • Coach dashboard + API licensing
  • Export tools and team tools for academies
