Rock & Run 5K - El Segundo

Rock & Run 5K - El Segundo takes place in El Segundo, California, on October 24, 2026, with a single 5K (3.1 miles) starting at 9:00 a.m.

Short and single-format, this is the kind of race you can drop into a training block without rearranging anything around it. Run it hard and it becomes a fitness test; run it at threshold effort and it is simply a good workout with a crowd. Either way you will not need more than a couple of easy days afterwards. If you are targeting a personal best, spend four weeks on repetitions slightly quicker than goal pace — 400s and 800s with short jogs — and keep one longer run a week so your endurance does not slide. Beginners can finish 3.1 miles on two months of running three times a week.
