Train like an elite athlete with just your watch.

Diastra plans every week in three heart rate bands and holds you in them on every run.

Every run

Your wrist tells you when you are in the band.

A short voice line says when you are in, when to recover and when the last one starts.

After every run

See if your easy run was really easy.

Diastra draws your heart over your band and credits only the minutes that held.

Every morning

Hard days wait until you are ready.

When Diastra reads Overreaching, it offers to take the hard sessions out of your week.

Every week

Your week gets its minutes in each band.

The plan redraws itself after every workout.

Over the year

See your pace get faster at the same heart rate.

Diastra lines up your steady runs at one heart rate and shows your pace a year ago and now.

As you get fitter

Your bands grow as you do.

Diastra redraws every band when a run shows a higher max heart rate.
