The Out and Back

Thinking Differently About TSS and CTL (maybe use something else?)

Endurance athletes rely on metrics to understand training load, fatigue, and readiness. But tools like TSS and CTL are built on assumptions that do not always reflect the complexity of the body. In this episode, we’re joined by two product experts from Wahoo, Alia Shafi and Mac Cassin.
