In the flurry of high fives, water hand-offs and costumed racers, follow these 6 tips for spectators and you'll be watching the marathon like a pro.

Have a plan
If you have a runner in the race, use the course map to figure out where you will watch the race and communicate which side of the street you'll be on. If you're aiming to hit multiple spots along the route, map out which mile marker your runner will be at during particular times, based on their planned pace.

Track your runner online
Visit to keep tabs of your runner throughout the race. Electronically track multiple runners on the course by entering participant info on the website. Updates will be received as runners cross the 10K, halfway (13.1 miles) and 30K checkpoints, as well as the finish line.

Stand out in the crowd
To help your runner spot you among the sea of spectators, dress up in costume, bring a bright neon sign, or wave a big balloon or flag as they runs past. Be loud and be creative!

Take public transportation
Use the CTA and hop on the ‘L' train to get to the start and finish line, as well as various mile markers near train stations throughout the downtown and neighborhoods. For example, the Blue line stop at UIC-Halsted is near MILE 16 in Greektown and the Red line stop at Grand is near where the runners cross the Magnificent Mile at MILE 1.

Hit the neighborhoods for live entertainment
With 26.2 miles spread out across the city, there's no reason to stay just within the Loop! Cheer on with the locals in the communities of Pilsen at MILE 19 and Chinatown at MILE 21, where upbeat mariachi music and colorful lion dancers entertain the crowd. Mix it up with live animals for the kiddies at Lincoln Park Zoo between MILE 5 and 6, or go for the block-party atmosphere of Boystown surrounding MILE 7.

Make an appearance after MILE 20
After a few hours, the course takes its toll and runners need extra support for the last few miles which are concentrated on the South Side. Show up by taking the Orange line to Halsted (MILE 20.5), the Green line to 35th-Bronzeville-IIT (MILE 23) or the Red line to Sox-35th (MILE 23.25) to give them a final burst of energy before the big finish.
