The Chicago "L" challenge is one of the oldest independently tracked transit speedruns online, with record listings dating back to 2011. The "L" network has been in flux for several years since, with numerous station closures and reopenings meaning that it has been difficult to define the true nature of this challenge.
State/Lake is closed until 2029. We will NOT reset the leaderboard during this closure, but you will still be required to pass through the station on the Loop.
