This post marks the beginning of the SFS story.

We are building SFS around one simple but important goal: to make training for endurance athletes more effective, more accessible, and, above all, safer.

Our aim is to bring together data, technology, and real training experience to help athletes better understand their condition, manage training load more precisely, and make better-informed decisions throughout the training process.

This is only the beginning. In the next posts, we will share how SFS is evolving, the problems we are working to solve, and the technology behind the system.

The SFS story begins.
