Map and notes courtesy Lifetime Chicago Triathlon.

The bike leg begins by traveling to the left of the middle of the cul-de-sac.  Using the on ramp to northbound upper Lake Shore Drive the course heads north using the inner two lanes.

The riders continue on Lake Shore Drive until the turnaround near Foster and then return on the inner two lanes (heading south).

At Chicago Avenue, the sprint distance competitors continue south straight through to the bike finish while the international distance competitors U-turn to complete another lap of the section to Foster.

The bike finish is executed by U-turning onto the southbound Randolph entrance ramp to Randolph and turning right onto Randolph.

Please Note: We have made a significant change to ensure a safe and competitive racing landscape in 2010 for our Professional Race which starts at noon. We will be enforcing a very strict age group division cut-off on the bike course. There will be a 12:15pm 2nd lap cut off for age groupers. You WILL be allowed to finish the race but will NOT be included with Age Group Awards. You will still get finish time/splits.
