What's New in Endurance Debrief

3.3

October 11, 2026

Refresh older workouts. • When you import a file again, you can now replace the existing workout: zones, best efforts and TSS are recalculated, title and sport stay. The preview shows the previous TSS first. • Several files at once: Debrief re-imports workouts that already exist after a single confirmation. • This way, GPX and TCX runs from before 3.2 get the more accurate pace zones too. • Importing several files: a note when GPX rides contain no power data. • More accurate fitness curve when replacing workouts around midnight. As long as you don't re-import anything, all existing values stay unchanged.

Absolut Empfehlenswert

Ich bin absolut begeistert von dieser App! Was mich am meisten überzeugt hat, ist die problemlose Handhabung von TIF-Dateien. Während diese bei Garmin bei mir ständig zu Upload-Problemen geführt haben, lädt diese App sie absolut reibungslos und ohne jegliche Fehlermeldung hoch.
Auch die Datenanalyse ist einfach genial – extrem übersichtlich, präzise und bietet genau die Einblicke, die man für sein Training braucht. Ein riesiger Pluspunkt ist für mich zudem der Datenschutz: Es ist alles komplett privat und nur ich selbst kann meine Ergebnisse einsehen.
Vielen Dank an die Entwickler für dieses tolle Tool. Absolute Weiterempfehlung!
