Starting point
Marc came in as a 5K runner — a single-discipline athlete with no long-course triathlon history. Everything beyond the run had to be built rather than sharpened.
The goal
Finish a full-distance IRONMAN — without the build costing him his clinical work, his research, or time with his three children.
The constraints
In Marc's own description, the training had to fit around clinic, the lab, and three kids. That is three hard, non-negotiable time blocks competing with a 140.6-mile build, so the week had to be efficient rather than long.
The result
Marc finished IRONMAN Arizona in 9:35 at age 39 — his first full-distance race. Along the way he ran a 16:57 5K and went 4:30 at the half-iron distance.
How is the result documented?
These results are attributed to Marc’s supplied testimonial. The original archive links an IRONMAN results directory, but it does not provide a matched individual result record. This case is labeled athlete-reported rather than independently verified.
