Welcome

Stop guessing
when to run.

Runcastr reads tomorrow's weather hour by hour and hands you the one window worth lacing up for — skipping anything during work.

Step 1 of 3

Where do you run?

We just need your location to pull real weather for your area — nothing to type.

Step 2 of 3

When do you work?

Runcastr will never suggest a run during these hours.

Step 3 of 3

When do you sleep?

So we never suggest a run before you're awake or once you're winding down for bed.
