From the Organizer
The 4 on the 4th is back!
We're returning to our traditional 4-mile out and back course up Oenoke and West Road, starting from St. Mark's Church and finishing in the Nature Center driveway.
One definite change: No in-person race day paper registration! Online registration will remain open until the 8 AM start time. Register at home prior to the race, or on your phone when you arrive at the race site, then go to the check-in station.
There will be pre-race check-in at Darien Running Company Friday July 3 from 3 to 6 PM (not 2-5 as originally posted).
