Roads closing for La Jolla Half Marathon, 5K

As the La Jolla Half Marathon and 5K races wind their way toward the finish line at La Jolla Cove, some roads will be closed for parts of the morning on Sunday.

About 7,000 runners are expected for the 29th running of the signature 13.1-mile race, with an additional 2,000 signed up for the 5K.

With the starting point for the half-marathon at the Del Mar Fairgrounds, the southbound lanes of North Torrey Pines Road will be closed from Carmel Valley Road to La Jolla Shores from 8 a.m. to approximately 9:30 a.m.

Other streets will stay closed later because they are toward the end of the event, which is expected to wrap up by 11:30 a.m. Both sides of the smaller streets are used except along Torrey Pines Road, where one lane is used, and one side of Prospect Street going toward the Cove is also utilized by runners.

Access to La Jolla Shores will not be restricted.

In the past, the race has seen an increase in its participants each year. That trend continues this year as well, but it may be the last time in the foreseeable future. During the last 15 years, the race has gone from 3,000 participants in 1994, to 5,500 in 2007.

On Saturday, a race expo will be held from 9 a.m. to 5 p.m. at the La Jolla Recreation Center.
