IRONMAN 70.3 Santa Cruz 2026
A cold Monterey Bay swim around the Wharf, an out-and-back on Highway 1 to Pigeon Point, and a coastal half marathon finishing on the sand.
4 weeks to race day: the sharpening window
A full build no longer fits, but a sharp one does. This close in, the job is specificity and freshness: race-pace touches, open-water or brick rehearsal, and a taper your nervous system actually absorbs. No heroics; arrive fresh.
Building for this one? 70.3 training plan covers the sessions, the weekly shape and how the block is paced. The R.A.C.E. Framework explains why it is built that way.

Commit to the date and the work gets a shape: your countdown starts, the emails arrive in step with your build, and the app anchors a recovery-led block so the final week lands exactly on race day.
One confirmation email, then the road begins. Registering for the race itself stays with the organiser.
“Sixteen degree Pacific water and a finish run on soft sand. Neither is hard on its own; both are worth one practice session each before you get there.”
The race
The course
No course maps for this race. IRONMAN publishes no downloadable route for any leg of this race, only a live tracker that runs on race day, so there is nothing to draw a course map from. Everything below comes from the official course page, checked on the date at the foot of this section.
Starting on Santa Cruz Main Beach next to the Boardwalk, clockwise around the Wharf, exiting at Cowell's Beach. Cold Pacific water at around 16°C. The official page does not state a lap count.
From Depot Park north on Highway 1 along the coast to a turnaround near the Pigeon Point Lighthouse, then back the same way. An out and back rather than a loop, on one of the best-known coastal roads in America.
An out and back from Depot Park over the West Cliff Bridge onto the West Cliff Path, around Natural Bridges State Park and out to a turnaround on the bluffs at Wilder Ranch. Mostly flat and fast, and the last 100 yards are run on the sand at Cowell's Beach.
Not yet confirmed for this edition: swim lap count, bike lap count, bike elevation gain, transition locations, cut-off times, water temperature history. We publish these only once they are on the official course page, so check there before you pace off anything here.
