The 2021 Chicago Spring Half Marathon & 10K is going Virtual!

May 20 – 23, 2021

To keep the spirit of the Chicago Spring Half Marathon & 10K alive, we’ll be hosting the event virtually this May! With the flexibility of a virtual event, our goal is to bring the full race experience and motivation to you, wherever you are. Sign up for this event and continue daydreaming of spring flowers, warmer temps, lakefront breezes and simply running outside!


March 22 – May 16, 2021

We challenge you to Run the L! Run (or walk, wheel or bike) the entire distance of Chicago’s elevated public transit system. We’ll give you 8 weeks to tackle 131 miles. Do it solo or grab a running buddy to divide and conquer this unique challenge!

We’ll give you the motivation you need each week as we take on a new line between March 22 and May 16.

Run the L is a great way to prepare for your Virtual Chicago Spring Half Marathon & 10K.
