Fartlek Interval Trainer

What it does

Fartleks - spontaneous running training sessions without planned intervals - are recommended by coaches to improve stamina and speed. Most interval timers just tell you when to start and stop running - no use if you're being spontaneous. Fartlek Interval Trainer puts you in control. It tracks when you're running, walking or stationary, turning your workout into a visual breakdown showing when you ran hard, and when you rested. Now you can run intervals without having to plan in advance.

The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
