Career Mod Help

[DaveC187]

I am trying to create custom career series. I have been successful setting up series races set by laps. But I wanted to create race series set by 30 mins (or time rather than laps). Does anyone know what I need to change to create race series by time instead of laps?

This is what I currently have, at this set-up, the AI cars pit at the end of lap 1 and stay in pits. Any help would be appreciated.
