Ready to race the Half Distance Oceanside Triathlon? This race isn’t just scenic—it’s demanding. With a 1.2-mile swim in the chilly Oceanside Harbor (avg. 61°F/16°C), a 56.2-mile ride through Camp Pendleton’s military base, and a 13.1-mile coastal run with elevation shifts, success requires more than grit. You need a smart, structured, and course-specific plan—and that’s exactly what this is.
