Smarter Training Through AI Video Analysis

For Runology

Overview

A mobile platform that turns a simple running video into detailed biomechanical insights — helping athletes train smarter and reduce injury risk.

The Situation

Professional running analysis was reserved for elite athletes and expensive labs.

For most runners, improving technique meant either hiring a coach, visiting a specialized sports center, or simply guessing what to fix. Biomechanical analysis — the kind that tracks joint angles, body posture, and movement phases — required expensive equipment and trained professionals to interpret the results.

Runology set out to change that. The vision was clear: give every runner access to the same quality of technique analysis that professional athletes get — using nothing more than a smartphone camera.

The Real Problem

Recording a video is easy. Turning it into actionable insights at scale is not.

The real challenge wasn't the AI itself — it was everything around it. Each uploaded video needed to be processed through an AI engine, enriched with skeleton overlays, phase markers, and angle measurements, then cut into segments with slow-motion highlights. All within 20–30 minutes.

Now multiply that by dozens of users uploading simultaneously. The platform had to handle unpredictable spikes in demand while keeping costs low enough to offer affordable pricing — all without compromising the quality of visual feedback that makes the analysis genuinely useful.

Key Decisions

Serverless Video Pipeline

Each analysis runs independently in the cloud, scaling automatically with demand. No servers to manage, no bottlenecks when dozens of runners upload at the same time.

AI-Driven Biomechanics

The platform tracks key body points — knees, shins, feet — measuring angles at critical moments and comparing them against optimal movement patterns.

Rich Visual Feedback

Results go beyond numbers. Skeleton overlays, running phase markers, and angle visualizations are rendered directly onto the video — making insights intuitive and actionable.

Sub-Dime Unit Economics

The entire video processing pipeline costs under €0.10 per analysis, enabling an accessible price point for everyday athletes.

The Outcome

Professional-grade analysis, available to anyone with a phone.

Runology turned biomechanical running analysis from a specialized lab service into something any runner can access in minutes. Record a video, upload it, and receive a detailed breakdown of your technique — complete with visual overlays that show exactly what to improve.

The serverless architecture means the platform scales effortlessly with growing demand while keeping operational costs minimal. For runners, it's a personal coach in their pocket. For Runology, it's a scalable product with strong unit economics built into its DNA.
