San Diego residents will soon have a chance to donate to a worthy cause while keeping in shape. StayClassy, a nonprofit organization, will hold its fourth annual Fire Run/Walk on Sunday, Aug. 29. The event — which seeks to raise funds for several local nonprofit organizations, including San Diego Fire Rescue Foundation, Surfrider Foundation, Make-a-Wish, Jeans 4 Justice and Volunteer San Diego — will begin at 8 a.m. at the intersection of Prospect and Girard streets in La Jolla. It will end at the intersection of Mission Boulevard and Felspar Street in Pacific Beach, event organizers said. Pat Walsh, the organization’s co-founder, said participants will be asked to donate at least $5 to an organization of their choice and have the option of contributing additional funds. Officials expect nearly 3,000 runners and spectators. Walsh said the event has already collected more than $6,000 this year, surpassing last year’s total of $5,000. He said officials are aiming to raise a total of $10,000. “It’s a great community event,” Walsh said. “It’s been a really enjoyable event for everyone.” Walsh said awards will be presented to participants in three separate age divisions. The top male and female runners will earn $500. The event will feature live music, a beer garden and giveaways, Walsh said. A free shuttle service also will be available to get participants back to their vehicles after the race. The advance registration cost is $35 or $40 on the day of the event. Nonrefundable checks may be mailed to End of Summer Run, 7801 Mission Center Court, Suite 204, San Diego, 92108. Runners may also pre-register Saturday, Aug. 28, from 10 a.m. to 1 p.m. at PB Bar and Grill, 860 Garnet Ave. in Pacific Beach. Registration on the day of the run will be from 6:30 to 7:50 a.m. on the 900 block of Prospect in La Jolla. A post-race party, which will offer water, juice, oranges and bagels to all runners, will be from 8:30 a.m. to noon. Sponsor booths and local vendors also will be on hand. The event is directed by Kathy Loper. For more information, visit www.kathyloperevents.com/end-ofsummer4m or www.stayclassy.org/la-jolla-/events/2010-san-diego-fire-run/e2228.
