On Aug. 13, CTA columnist Tracy Swartz completed the "L" challenge: consecutively visiting all 145 CTA stations. Only public transportation and walking/running was allowed in between the stations. Taxis/bikes were not OK. It took 9 hours, 17 minutes to complete. The start point was the 95th Street Red Line station and the finish point was the 54th/Cermak Pink Line station. Here are photos of the rest of the journey.
