JACKSONVILLE, Fla. -

Gate River Run Race Director Doug Alred announced that online registration for all River Run events will close at midnight on Monday.

The 15K registration will close sooner if the 20,000 entry limit is reached. He urged all who are planning to run the 15K to register now to avoid the possible disappointment of a closed field, and noted that the 20,000 limit for the 15K could be reached before the Runners' Expo begins on March 8.

Runners may register at gate-riverrun.com. The Florida Times-Union 5K for Charity, Adidas Junior River Run, and the Brooks Mile Challenge will accept registrations throughout the Runners' Expo at the Jacksonville Fairgrounds March 8 and 9.

Additional information is available at gate-riverrun.com or the race hotline at 904-731-1900.
