PROGRESS YOU CAN UNDERSTAND
A run is just the beginning.
A level backed by evidence.
RUN LEVEL is a model estimate from suitable runs. The evidence grows with enough recent, varied data.
More than a higher number.
Easy runs and a sustainable rhythm matter too. Not every workout needs to raise your RUN LEVEL.
Can I download the app yet?
RUN B RUN is still being tested. Leave your interest below; a public download will appear here when available.
What does the example level of 5.2 mean?
This is a fictional profile with 42 runs. The app calculates its level and evidence score from those runs. The growth from 3.0 to 5.2 is example data, not a prediction of your progress.
Does every run contribute to my level?
No. Only runs with suitable measurement quality and effort contribute level evidence. Your other runs still remain in your history.
How does drawing a route work?
Place your own points. The editor connects them with straight segments. Check that each segment follows a suitable path; manual drawing does not automatically follow roads.
Do I need an account?
Friends and challenges require an account. The app also includes local tracking and local run history.
Does RUN B RUN work with a sports watch?
Wearable data import is built and being tested. Support and reliability on physical devices still need further validation.
