The 3m Half Marathon and Half Marathon Relay has reached its cap of 6000 runners and is a sell out. Registration for the January 29th event has closed out and 3M will no longer accept any entries.

The 3M race is one of the fastest half marathon courses in the country and is a perennial favorite. It starts at 6:45 a.m. on Stonelake Boulevard, just outside of the Gateway Shopping Center in north Austin. The course follows a mostly downhill route, but this year the race finishes at the Bob Bullock Museum, just north of the Texas State Capitol.
