Daniel Fernández Raventós

Daniel Fernández Raventós

PhD in sport sciences, specialised in performance analysis in team sports. Ultra-cyclist.

Ulter was born from the need to have the metrics that Strava doesn't provide when you do events lasting many hours: how long you stopped, where you slept, how your performance evolved as the night went on.

A tool built for personal use that we now share with anyone who might need it.
