The Lake Monona 20K Run and 5K Run/Walk, taking place on Saturday, May 2, 2026 offers a beautiful course with springtime temperatures ideal for running, and combines small-race feel with big-race perks. For those with longer distance ambitions, this “almost” half marathon is a great way to peak your spring training, or to prepare for a spring marathon. For those interested in a shorter distance to tackle, there is also a 5K run/walk option.
