March always has been a busy month for organizers of the Allstate Sugar Bowl Crescent City Classic.

But their month’s work was taken to another level when the Allstate Sugar Bowl St. Patrick’s Day Classic was added to the running calendar three years ago.

This year’s St. Patrick’s Day Classic will be at 10 a.m. Sunday, and it will precede the Metairie Road St. Patrick’s Day Parade. The two-mile race will begin at Gennaro’s Bar, located at 3200 Metairie Road and North Causeway Boulevard. The race will travel along Metairie Road, and end where it meets Frisco Avenue.

Only 1,000 participants will be allowed to register, and CCC Event Manager Laine Thomas said she expects all spaces will be filled by the time the race begins. Last minute-registrations — if available — will begin at 8:30 a.m. at Gennaro’s on Sunday.

“The St. Patrick’s Day race is very close to the Classic this year because Mardi Gras was so early,” Thomas said. “So this is the last chance people will have to qualify for the Classic. Plus, it’s also a chance to qualify at the shortest distance. We’re expecting a lot of people to try to qualify for faster spots in the Classic by coming out to this race.”

To qualify for the A group in the CCC, you must run the St. Patrick’s Day Classic in 10 minutes, 50 seconds or faster. To get in the B group, you must run a 12:25. You have to post a time of 14:00 or faster to be in the C group.

Both races are open to competitors of all abilities, but the faster groups in the CCC offer talented runners coveted spots with less racing congestion.

Cost to register for the St. Patrick’s Day Classic is $25 if signed up in advance (online registration closes at approximately 5 p.m. Friday. Cost on race day is $30. Fee includes an official race T-shirt and access to a postrace party at Winston’s Pub and Patio (531 Metairie Road.) Different establishments along the course will offer drink specials to race participants throughout the day.

A $5 registration discount is offered to all military personnel, including active duty, retirees, reserves, National Guard, dependents of military, and U.S. Deptarment of Defense employees.

A portion of race proceeds will benefit ongoing improvements to Wally Pontiff Jr. Playground. The remainder of the proceeds will go to the Crescent City Classic Foundation and the 15 local “Run For It” nonprofit organizations it supports.

Walkers and persons with strollers are encouraged to register, but asked to line up near the back of the pack on race day. Parking is first-come, first-serve in on-street spaces. Arriving early or being dropped off near the starting line, is advised.

The 10K Crescent City Classic, one of the largest races in the South each year, will be held March 26.
