Santa Clara, United States of America · Saturday 23 January 2027
The Sun Marathon in Santa Clara takes place in January 2027 on a moderately hilly road course that spans 42.2 kilometers with about 211 meters of elevation gain spread across terrain ranging from 885 to 1397 meters above sea level. The rolling hills mean you'll need to manage your effort carefully rather than settle into a steady flat-road rhythm, particularly in the middle miles where the elevation changes compound fatigue. Santa Clara's location in the San Francisco Bay Area puts you at altitude, so arriving early to acclimate will help you avoid feeling the thin air during the race. This is a solid choice if you want a real workout that tests your hill fitness without being a mountain marathon, and the January timing offers cooler conditions that should help with pacing.
