HOW IT WORKS
Four steps. A plan that feels like yours.
Set your direction, shape your week, then keep an eye on the training ahead. The app gives you the detail without making the first step feel complicated.

MADE FOR REAL LIFE
A good plan should bend before it breaks.
Holidays happen. Work gets busy. Some weeks need to be lighter. Build42 is designed to take your availability into account and let you review changes to future training.
There is a reason behind the plan, and you can see more of it whenever you want.
Explore how plans workGOOD TO KNOW
Start with what you have.
Do I need to link a health service?
No. With your separate permission, Build42 can use recent runs from Apple Health on iPhone or Health Connect on Android. You can also enter your recent running background manually.
Do I need an event date or target time?
No. Choose a distance first. An event date and target time are optional; Build42 does not invent them for you.
Can I download Build42 now?
Build42 is in private testing and is not yet available from the public app stores. You can request beta access through the Project42 Apps contact form.
