Anduril 250

The Anduril 250 moves NASCAR's street-racing experiment to the West Coast, closing the Cup Series' three-year run through downtown Chicago and opening a new chapter on the San Diego Street Course. At 3.4 miles, the temporary circuit is among the longest tracks on the Cup schedule, a sprawling layout that mixes long acceleration zones with tight, walled corners where track position is won under braking. The race runs 75 laps and 255 miles with stages at laps 20 and 40, and it streams exclusively on Prime Video, part of NASCAR's push to pair new venues with new audiences. Street courses compress the field's usual hierarchy: there is no historical notebook, practice time is short, and the walls punish the small errors that ovals forgive, which opens the door for road racing specialists and bold strategy calls. The inaugural 2026 running delivered on that promise, producing 20 lead changes among 13 different leaders before Corey Heim, the Truck Series star moonlighting in a 23XI Racing Toyota, drove off to a 10-second victory from 13th on the grid. A points-paying Cup race on California streets would have been unthinkable a decade ago; now it anchors one of the most ambitious weekends on the calendar, with all three national series racing the same city blocks.
