Students Run LA (SRLA) is bringing together alumni and runners from across Los Angeles for an easy, flat 5K course around the Griffith Park Golf Course. Walkers and runners of all levels are encouraged.

Following the 5K, enjoy a post-race picnic, DJ, and time with some of SRLA's longest serving volunteers.

All proceeds support Students Run LA.

SRLA creates a safe, supportive community at 180+ public schools across Greater Los Angeles, welcoming more than 3,000 students of all backgrounds and abilities to train alongside their volunteer mentors to complete the Los Angeles Marathon. Through this life-changing experience, students discover their best selves and learn how to make plans for the future.

Each year, students become active 10+ hours a week; 95+% of the students who attempt the Marathon, finish it; and 95+% of SRLA seniors graduate from high school with plans to attend college the following fall, with 2/3 being the first in their families to do so. Students also incorporate healthy living in their daily lives with 87% continuing to exercise after SRLA ends.
Join SRLA alumni and your favorite LA run crews for a 5K race.

2018 Tikim Filipino Food Fun Run @ Los Angeles Historic Park
Dec 15 all-day
2018 Tikim Filipino Food Fun Run @ Los Angeles Historic Park | Los Angeles | California | United States

Race day is coming up and we still need more volunteers. We're on the lookout for people to help with some of the below. Not all races need all areas, but this is a general idea on where you may be assigned the morning of the race:

Parking Direction

Positioned near and at the entry to designated parking areas to direct athletes, attendees and other volunteers to correct parking areas, registration area and event plaza.

Water Stations Along the Course

Fill cups of water at water stations along course. Maintain filled water cups for runners/walkers as needed. Clean up post race, throwing all empty water cups into trash receptacles.

Food & Beverage Tables

Cut bananas, oranges and bagels as well as set up tables. Additionally, hand out to runners and walkers before and after they run/walk.

Course Direction & cheer stations

Positioned at various key points along the course, volunteers will point or holds signs to keep runners/walkers on the proper course. Cheer the runners and walkers on as they participate in the race.

Course Worker

Assist with the set-up and breakdown of course by removal of cones, signs, course water tables and containers of water.

Event Day Registration

Welcome athletes, collect registration information, distribute race packets, race t-shirts and goodie bags on race day.

Finish Line

Assist with sorting of athletes as they finish the run/walk, handing out finisher medals and keeping order in the finish chutes.

Awards Booth

Assist with sorting and distributing age group awards to top three finishers in each age group.

Breakdown and Clean-up

All volunteers are asked to assist with the breakdown and clean-up of the course, start & finish line area and event plaza area.

Depending on the race, Kiddie Fun Run Course Volunteers

Positioned along the Kiddie Fun Run course, volunteers will ensure all participants follow and stay on course.

As an A5 Events volunteer you will be fed and hydrated.

If you have any friends or family that also may be interested in volunteering, please have them sign up through this website or show up with you on the day of the event. You will be assigned a job at the event.

Without our amazing volunteers, this race simply would not happen. So on that note, thanks and we look forward to hearing from you.

Please show up at 7:00am.
