Carlsbad Marathon & Half Marathon 2026
Carlsbad, United States of America · Monday 18 January 2027
Expect a relatively flat, scenic coastal course with minimal elevation challenge - only 178m total gain keeps the terrain rolling gently between 4m and 21m altitude, making this ideal for pursuing a fast time. The Carlsbad location suggests you'll enjoy Pacific Ocean views and beach-adjacent running, though prepare for potential coastal wind and sun exposure along the exposed sections. This is a runner-friendly course for PRs if you're fit, but still bring sunscreen and hydration strategy for the oceanside conditions.
