Evanston’s lakefront path is flat and well-maintained, with sections that can be run either alongside or directly upon the shared paved route. Runners will encounter stretches of crushed gravel but also have options to stay on firmer grassy areas if preferred. The weather in early September typically ranges from mild temperatures around 19.8°C (67°F) and lower humidity levels, providing a comfortable environment for endurance runners.
This event has grown significantly since its inception, now attracting over three hundred participants annually who aim to test their limits across various distances. Proceeds support local community initiatives within Evanston, emphasizing the importance of supporting grassroots running communities in Illinois. The Half Day at the Lake offers more than just competition; it is a celebration of endurance and camaraderie among runners.
The race course follows a 2-mile loop along the lakefront path near Northwestern University’s campus, featuring flat terrain that transitions between paved surfaces and crushed gravel sections with nearby grass alternatives for varied running conditions. Participants will start and finish at Sheridan Road in Evanston, where the route offers scenic views of Lake Michigan throughout its entirety.
Weather forecasts indicate mild temperatures ranging from 15.9°C to 23.6°C (60°F to 74°F) on race day with an average wind speed of approximately 11.3 km/h and humidity around 72%. The UV index is expected to be moderate at a level of five, making it suitable for outdoor activities without excessive heat or sun exposure.
The Half Day at the Lake offers runners two distinct options: a 6 Hour Race with an early bird registration fee of $60.00 before July 15th and regular pricing starting from August 1st, as well as a 12 Hour Race initially priced at $70.00 until July 15th and increasing to $85.00 thereafter.
