Today is the last day to register for this year’s Hawaii Pacific Health Great Aloha Run, organizers said. This year’s run, on Feb. 18, will be celebrating its 35th anniversary.

To register online, go to greataloharun.com/registration. There are several categories to select from, each with a different entry fee.

Runners can also register at the Great Aloha Run expo Feb. 16 and 17 at the Neal Blaisdell Center.

Last year, about 18,000 runners ran the 8.15-mile course from Aloha Tower to Aloha Stadium. The race starts at 7 a.m., and the awards ceremony and entertainment will begin at 8:30 a.m. at the stadium. Some downtown streets will be closed starting at 4 a.m.

The race has raised more than $12 million for organizations and groups throughout Hawaii.
