BYB is your training companion for long distance runners only.

Training well requires a lot of experience and doing it right is actually closer to an art than an exact science.
Here comes BYB; an analytics tool that helps you understand when you train rather well or - on the contrary - when you over train.

Key features:
- Journal for runners. Go beyond a simple time/distance log, and record your interval training or long run in the best way

- Contextual analytics:
 All “one hour activity” are not run equal. BYB helps you answer questions like “How did I do?” And “Am I on track for a Personal Best”?
