GOOD LUCK, ATHLETES!
Celebrate the City in Bloom
Revel in the changing of the seasons at the Life Time Chicago Spring Half Marathon & 10K! Get ready for a breathtaking race experience just for you. The Half Marathon, 10K, or Junior Dash distances are designed to help you celebrate spring along our scenic lakefront, with amazing views and refreshing lake breezes. And the run is only the start of the fun. After the finish line, join us in our Spring Market Festival, featuring a delicious brunch, picturesque photo ops, a lively beer garden, live music, and even a flower planting station where you can take home your own spring bloom. It’s the perfect way to celebrate spring!
JOIN THE FUN!
There’s a race for everyone.
Sign up for the Chicago Half Marathon Series (the Spring Half and the Chicago Half) and experience the thrill of running in one the world’s most iconic cities, in two different seasons. Complete both and earn some extra hardware!
Our half marathon is perfect for runners looking to test their endurance or for those seeking a new challenge. With stunning city views, surrounded by supportive spectators, you’ll be motivated to reach your personal best.
Looking for a shorter distance? Our 10K offers a great opportunity to challenge yourself without tackling the entire half marathon. Enjoy the same vibrant atmosphere and scenic course, while still pushing your limits.
Bring the whole family! Our Junior Dash is designed for young runners under the age of 12 and lets kids experience the excitement of a race in a fun and supportive environment. It’s the perfect way to get them stoked on running!
