Your running.
Your goal.
Your week.
A training plan should fit your life—not the other way round. Build42 brings together where you are now, what you’re aiming for and the days you can realistically run.
Not yet available in the public app stores. Beta requests are handled through Project42 Apps.
THE BUILD42 TOUR00:30
A silent look inside the app, from first setup to plan progress. Video examples use demonstration data.
One clear path from where you are to what comes next.
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.
02 / AIM
Choose a goal
Pick a distance. Add an event date if you have one; you don’t need a race booked to begin.
03 / PLAN
See what’s next
Choose the days you can train, then see easy runs and long runs laid out week by week.
04 / GROW
Check progress
See completed, upcoming and changed sessions against your plan—without a made-up fitness score.
Screens show a private-test demonstration. The progress example contains self-reported sessions, not imported Health runs.
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.

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.
