Zepho
The world’s best coach in your pocket
The Challenge
Most endurance training apps offer the same thing: a generic plan that fails to adapt to the individual. Truly personalised coaching is typically reserved for elite athletes with access to high-cost, one-to-one support and specialist teams.
Our client was frustrated by these apps that didn’t listen to their training needs, they wanted access to an elite coach that could create training plans to meet their exact needs and goals. So they set out to change that.
We designed and built Zepho, an AI-powered endurance coaching app that pulls from an athlete's wearable data to generate personalised training, nutrition, and recovery guidance. Built around the individual, not a template.
Outcomes
At the core of Zepho's experience is a conversational interface: natural and immediate, it allows athletes to build a rapport with their coach. Athletes can ask about their training plans, review completed workouts, and get advice that accounts for how they're actually feeling.
Athletes in the early test program are already seeing real results from training with Zepho, enjoying the benefits of working with an elite level coach who adapts and grows with them. A coach who understands exactly how to get the best performance out of them, even when they aren't feeling 100%.
Endurance athletes generate a lot of data: raw activity metrics, sleep patterns, nutrition logs, mood, travel schedules.
Instead of dumping raw athlete data into a language model, we created a hybrid layer that processes and aggregates key metrics first, producing clearer insights.
We also tuned the AI specifically for endurance coaching, delivering far greater precision and a noticeably stronger experience than a general-purpose model.
Project Summary
Zepho partnered with Mettle to create an app that adapts to each athlete's goals, performance, and needs. Designed to integrate with leading wearable platforms, it enables smarter training, faster progress, personalised support and in depth analysis for endurance athletes of all levels.
