Step 1
Tell us where you’re starting
Choose your 5K goal, race date, current running ability, and available training days. Startline uses those details to create a baseline that fits you.
Adaptive 5K training
Always know your next run.
Startline builds a 5K plan around your ability, schedule, and race date—then adapts each next workout to how training actually feels.
Built for beginners and returning runners. No medical information requested.
Our promise
Progress without pressure.
No one-size-fits-all week one
Your first workout reflects what you can do now, from walking regularly to already completing a 5K.
No reckless progression
Startline changes one primary variable at a time and eases off when a session is too demanding.
One continuous loop
A plan that listens after every run.
Startline does not reveal a fixed schedule one week at a time. It maintains a living training state and uses your latest result to choose what comes next.
Step 2
Follow one clear next workout
Open Startline and see exactly what to do next: intervals, an endurance session, or an easy continuous run with warmup and recovery built in.
Step 3
Log how it actually went
Record completion, difficulty, time, and optional distance in about 30 seconds—without turning your run into a data-entry task.
Step 4
Let PacePath adapt the plan
Deterministic rules adjust one training variable at a time. Strong days progress modestly; difficult or partial sessions hold or reduce demand.
PacePath adaptation engine
Progress earned, not assumed.
Transparent, deterministic rules respond to your completion and difficulty. No mystery model deciding your training load.
