If you require a gear check bag, you may pick one up at the dedicated gear check area located at the southwest corner of Maggie Daley Park. Gear should be dropped-off prior to entering the start corrals.

In order to leave your personal items at gear check, participants must:

  • Step 1 – Remove all contents from your backpack or purse, place them inside the clear plastic bag, and fold your backpack to place it in the clear bag.
  • Step 2 – Attach the gear check tab from your race bib, using the beaded tie provided, to the bag for easy identification. You must display your race bib to drop off and pick up items from gear check. Baggage will not be accepted if your items are not properly stored inside the clear bag. All checked items must be visible.

Please note:
All items must be placed inside the CLEAR PLASTIC BAGS provided at gear check on race morning. Baggage will not be accepted if your items are not properly stored inside the bag.

  • Do not give your items to anyone other than the volunteers assigned to work at gear check. Life Time is not responsible for any lost or stolen items.
  • All bags are subject to search and seizure by the Chicago Police, event security and race officials.
  • Gear check closes promptly at 12:00 p.m. If you do not claim your items in time, please contact Athlete Services by email: All unclaimed items will be donated to a local charity 30 days after the event.

Life Time has partnered with Fleet Feet Training x CES to help you reach your next half marathon personal record! Pacers will be available for the pace/mile times listed in the graphic on the left.

Pacers will be wearing a specific blue “Chicago Half Marathon Series PACER” tank. Look for the Fleet Feet Training x CES Pace Team wearing blue tanks and holding their respective pace sign in the start corrals.

You do not need to sign up for a pace group in advance. Simply join the group on Race Day.

*Goal pace does not supersede corral assignment. Participants must start in their assigned corral.
