- Accessories Chafe and blisters end more 100 km races than fitness does.
Overview
Held in San Diego, CA, the Happy Chinese New Year 100 km Race is a trail event featuring an exceptionally demanding pace requirement. With an 11-hour time limit, the cut-off is tighter than 96% of 100k races and more generous than only 4%. Meeting this threshold requires maintaining a sustained pace of 6.6 minutes per kilometer across the full 100-kilometer distance, leaving virtually no margin for extended stops or a mid-race slowdown.
Entrants should expect an intimate race day. The event has a smaller field than 83% of 100k peers and is bigger than just 15%, recording 9 finishers in 2026 across its 5 editions. The route itself operates as a trail loop starting and finishing at the Canyonside Park Driveway, tackling 5.5 thousand feet of elevation change that runners must absorb while staying ahead of that aggressive clock.
