The Sun Run welcomes runners of all ages, walkers and families to come out and enjoy beautiful Forest Park in the heart of our city. The 5k run features chip-timing from Start 2 Finish St. Louis and the 1-mile offers a casual walk option. Every run / walk registrant will receive the official Sun Run t-shirt and sunglasses. If you are a past or current patient of SSM Health Cardinal Glennon, you can choose to receive the special red Sun Run t-shirt signifying you are a Glennon Kid! Shirt sizes are not guaranteed for registrations after September 21.
