Created by someone who has been participating in marathon and ultra running events throughout the Chicago-land area over the past 15 years, Running Is Fun Sometimes aims to bring more affordable, well-managed ultra races closer to Chicago.

The Inaugural Half Day at the Lake 6 and 12 hour race which took place on September 14, 2024 was the first of such efforts. Thanks to all the volunteers and runners for making such a successful race, we are now offering another 50K individual or relay race in July of 2025 in addition to the 2nd annual HDATL race which will take place in September 2025.

Running Is Fun Sometimes is dedicated to donating all proceeds in excess of race expenses to non-profit organizations in the area. Currently any additional proceeds from the Half Day at the Lake race will be donated to Connections for The Homeless in Evanston and/or the Cara Collective in Chicago.
