CHICAGO -- Tens of thousands of runners are expected to hit the streets for this weekend's Chicago Marathon.
The Chicago Transit Authority wants spectators and participants in Sunday's race to know there will be plenty of bus and rail service available. The CTA will run longer trains and run trains more often on certain rail lines during the marathon. Trains on certain lines also will start service earlier Sunday. Marathon events begin at 7:20 a.m.
About three dozen CTA bus routes will be detoured because of the marathon course. The CTA says the reroutes will last until 4 p.m. Sunday.
CTA officials recommend that those attending the marathon buy fare cards ahead of time. The CTA also says it will have employees on duty at select rail stations to provide travel information.
