More than 4,000 runners and walkers crossed the finish line in both races combined last year at the Chicago Spring Half Marathon & 10K, which is part of the Chicagoland Half Marathon Series (that also includes September’s Chicago Half Marathon).
The race is a largely fast and flat one. It unfolds near the elevation of the lake and the course never rises more than about 25 feet in elevation from its lowest point. There are rolling hills along the route — which starts along the Lakeshore Trail, near North Lake Shore Drive and East Randolph Street — there are also plentiful flat stretches.
Along the race route, runners will get to see some of the sights and attractions for which the Windy City is most famous. You’ll journey from the Navy Pier near the starting line to the trails that run alongside Lake Shore Drive southward down to where the race turnaround points occur, near the Field Museum, Shedd Aquarium and Soldier Field, the home of the National Football League’s Chicago Bears.
Runners make their way south along Lake Michigan for the first six miles of the race. The turnaround point at Morgan Point looks out onto Morgan Shoal. After that, runners then head back north along the lakeshore, passing the 31st Street Harbor, Burnham Harbor and Monroe Harbor to the finish line at Lake Shore East Park.
The course time limit is 3 1/2 hours. Runners will need to keep a pace of 16 minutes per mile or better in order to complete their 13.1 miles within the time limit. Organizers say the race will be open to a maximum of 6,000 entrants.

Hello ,
Yesterday afternoon I signed up for the half on May 21 race day but I didn’t get confirmation thru email can u confirm if it went thru . When I did my Chicago marathon in 2012 I got confirmation. Mybilling went thru thinking I was off a letter or number on my email.
Please let me know .
Thank u !!
WOW. I was very much looking forward to running this race with my mother, like we did a while back in 2010, when it was sponsored by Magellan Development. The price when I registered in 2010 was $58. The price for the same registration period today is $95. What justifies this ridiculous price increase? I’m afraid neither of us can justify paying that much for a casual, fun race.
My guess would be that you looked to sign up too late. I paid $75 for this race. Also, you get allot at this race the breakfast at the end of the race is almost worth the race entry alone!
will they be changing the course map for 2016 to run into town at all?
