The last American to win the men’s race was Khalid Khannouchi in 2002.

Tatyana McFadden won the women’s wheelchair race and Marcel Hug won the men’s wheelchair race.

More than 40,000 runners, from all 50 states and 100 countries, trained to run the 26.2 miles.

Security concerns were high this year after a mass shooting in Las Vegas that left 59 dead and injured 527.

The wheelchair participants kicked off around 7:20 a.m. and the first wave of runners took off at 7:30 a.m.

The preparations have been months in the making, but the last few days, the pressure has really been on to make sure the marathon goes off without a hitch.

The race got extra attention, after it was revealed the shooter may have had his eye on this year’s Lollapolooza after it was discovered Stephen Paddock rented rooms overlooking the fest, at the Blackstone Hotel.

Mayor Rahm Emanuel and city officials, worked to reassure everyone that Chicago police and federal officials have done their best to prevent an attack from an elevated level along the 26.2 mile race.

More than 1,000 additional officers were in place for the event and many will be working undercover. Police were also on foot, on bikes, and motorcycles.
