About Startline

Startline helps beginner and returning runners answer one important question: what should I do next to be ready for my 5K?

Instead of handing every runner the same calendar, Startline creates a baseline from your goal, current ability, race date, and schedule. After each workout, the PacePath adaptation engine uses your completion and perceived difficulty to choose an appropriate next step.

We believe progress should be gradual, understandable, and responsive to real life. That means advancing one primary training variable at a time, preserving recovery, and holding or reducing demand when a session feels too hard.

Startline provides general fitness training information, not medical advice.
