iRacing: Week 13 2025 Season 2 Schedule

Like every season, the last week of the season is the famous week 13. Week in which iRacing launches its new content and gives us all a chance to test the new content we have acquired in tests for fun.

However, there are still a handful of official series for those daring who prefer to compete and risk their licenses and iRating in this dangerous week. Let’s remember that every day we race on a different circuit.
