The Municipal District of Birr is an inland town in Ireland known for its scientific heritage and wide streets. L70065 Rush uses this open layout for a 3.7 km loop that requires little technical finesse, making it a gentle introduction to the discipline. With only 7 corners, the rhythm is steady and the transitions are forgiving, though the wide turns demand consistent throttle control to maintain a slide. The circuit plays free in the browser with no account and no install, while Birr sits just outside town.
