Reaching for the Cure Half Marathon, 10K, 5K & 1K

Sunday, March 26, 2023 • Irvine, CA • Course Map

Set for its 25th annual running here in this Southern California city near downtown L.A., this half marathon is part of the Pediatric Cancer Research Foundation Reaching for the Cure Run & Ride, to help support children with cancer and find cures for the cancers that affect children.

The race also features a 10K run, a 5K run/walk, and a 1K fun run, all of which will share the same starting and finish line near the campuses of Kaplan International College and Irvine Valley College, just off Jeffrey Road. (With the exception of the bike tour, which will start the previous day, Saturday March 27, also at Irvine Valley College.)

From there, runners in the half marathon will follow an out-and-back route that takes them along a combination of city streets and tree-lined trails, including stretches past Oak Creek, Windrow and Woodbridge Community Parks as well as William Mason Regional Park, a 345-acre Orange County park where runners will follow the route right through the heart of the park in the second half of the race.

Runners will experience an overall downhill slope during the first half of the 13.1-mile route, the first few miles of which unfold along the roads and trails that run roughly parallel to the Barranca Parkway.

Once runners hit Woodbridge Park and turn left toward South Lake, they begin the stretch that takes them down into William Mason Regional Park, which also starts the uphill incline that unfolds through the second half of the course.

Following the race at the finish line, organizers add that runners and their families and friends can take in a range of entertainment, from live mariachi bands to an interactive video game truck, rock climbing wall, kids bounce houses, train rides, and more. For the adults, there will be a beer garden and plenty of food.

Prizes are awarded for the top 3 male and top 3 female finishers in each age division for the half marathon, 10K Run and 5K Run. Prizes also will be awarded for the top overall male and female runners in each race as well.
