Chicago Lakefront 50K - George Cheung Memorial Race Description

Registration is planned to open on 1/1/2021 or sooner! 

Race details below may change due to COVID restrictions

 Location: Southside Location. The Start/Finish Area is located at Jackson Park, 6300 S. Lake Shore Drive, Chicago, IL 60649, on the West side of Lake Shore Dr.

50K race starts at 8:00 AM (8-hour time limit)

Early Start Option:
Early starts are available to any runner who wants to do so but you will not officially be in the competition (overall or age group).  The way it works is to first see Pat Onines (Co-Race Director) on race day at the Start/Finish area.  He will add you to the early start list.  He will also mark the bottom of your bib # with an “ES”.  You may then start whenever you wish and time yourself.  You’ll be responsible to know the course especially where the turn-around is, and aid stations might not be available until the official race starts.  When you finish, you’ll get a medal and a “Finished” in the official results with no time.  Be sure to let the finish line crew know you were an early starter to avoid any confusion with those being timed.  They will take the bottom of your bib # and give it to Pat as evidence of your finish. 

Please remember that early starters or those that finish after the race time limit will have a “Finished” in the results but will not receive a position or a time.


  • Consists of 3 out-and-back segments for the 50k.
