Visit our course page for more information.
Lineup at Start of 5K and Kids’ 1-Mile Races
All participants in the 5K and Kids’ 1-Mile races will line up at the start/finish line based on their self-predicted finish time: the race director will call participants to line up in groups based on finish-time ranges. Each participant’s timing begins only when her/his bib passes the start line. Please check your bag at gear check before proceeding to the start line area. Strollers are allowed in the 5K but must begin at the back of the pack at the start line.
Determination of 5K and Kids’ 1-Mile Race Winners
The 5K and 1-Mile races will be timed on a digital clock connected to an electronic sensor (at the start/finish line) which detects the timing chip on each participant’s bib. In compliance with CARA (Chicago Area Runners Association) rules, the winner (male and female) of each of these races will be the registered participant who the race director sees crossing the finish line first, even if (highly unlikely) the digital timing indicates that another participant finished in a faster time.
Gear check will be available to all registered participants from 5:15 PM to 8:30 PM. Please be sure your bag is clearly labeled with your name before leaving it at gear check. The LeaderShop is not responsible for lost, damaged or misplaced items.
Bags may be left at the official gear check table ONLY. Unattended bags at the event will be immediately removed and discarded.
Each participant’s race bib will include a B-Tag timing chip. Please do not remove the B-Tag from your bib! It is the only way our timing system can tell when you cross the starting line and cross the finish line.
Results for each participant will include finish time and pace. Official results will be posted online (at active.com) by the following Monday, June 11th.
In order to receive an accurate time, please be sure your bib is:
- Yours . . . not accidentally switched with another participant’s
- Clearly visible on the front of your body (preferably above waist-level)
- Unaltered and unmodified: do not fold, crumple or add markings to it
- Pinned in all four corners
- Not covered (jackets, runner belts, water bottles, etc.)
