Bundled workout guide
Mona Fartlek Workout
The bundled Mona Fartlek moves from longer hard efforts to shorter fast ones, each paired with an equal-duration float. See every set and its app configuration.
What is this workout?
Fartlek means changing pace within a run. In this Interval Run template, each faster interval is followed by a float recovery of the same length. The effort blocks shorten from 90 seconds to 15 seconds.
The Interval Run template takes 35 min in total, including its warm-up and cool-down. The timed steps below describe the bundled app configuration, not a personal training prescription.
Choose the workout and effort that fit your experience and training plan. Stop if something feels wrong; consult a qualified professional about health concerns.

A detail to check before running
A float recovery is the easier interval between faster efforts. The app supplies the timing; choose the effort level using your own training guidance.
Use the timers as a guide to the structure; your training plan determines the effort and recovery that suit you.
