Join Caren Ware Events for the Lucky Trails Half Marathon & 5K, a scenic Irvine race weaving through the Jeffrey Open Space Trail and the Irvine Spectrum area. A community favorite kicking off the Southern California spring race season.

Course Description

Both distances start and finish at William R. Mason Regional Park. The 5K stays on flat paved trail loops around the park's lake. The Half Marathon heads out along the Jeffrey Open Space Trail before looping back through quiet Irvine neighborhoods — mostly flat with one gentle rolling section between miles 7 and 9.
