IRONMAN Santa Cruz
IRONMAN 70.3 Santa Cruz on 13 September 2026 starts with a 1.9 km swim in Monterey Bay, off a coastline where the water stays cold all year.
That is the headline fact. The Pacific here is fed by cold upwelling through the summer, so September brings no relief. A full wetsuit and a proper warm-up in the water rather than on the beach both repay the effort, and kelp is normal here rather than a problem.
The 90 km bike climbs out of town into the coastal hills before returning, so it is a rolling ride with a fast finish rather than the flat day the seaside setting implies. The 21.1 km run then works along the waterfront and the trails.
Fog is the other variable. Mornings on this stretch of coast are often grey and cold and can burn off into a hot afternoon by the time the run starts. Dress for the swim, plan for the run.
