My Swim Benchmark Session

Why It Matters

Data‑driven swim benchmarks translate directly into faster Ironman and 70.3 finishes, giving athletes a measurable edge in an increasingly competitive endurance market.

Key Takeaways

• Monthly swim benchmarks track performance and biomarker trends
• Supplement regimen boosted testosterone but vitamin D remains low
• Structured swim plan targets 110‑115s/100‑yd 2K pace
• Avoid equipment crutches; focus on consistent, purposeful training
• Benchmark times directly affect Ironman and 70.3 race odds

Summary

The video documents an ultra‑endurance athlete’s routine monthly swim benchmark, a data‑driven test designed to gauge both swimming efficiency and physiological markers. The creator explains how regular blood work—tracking testosterone, iron, vitamin D, and magnesium—has guided supplement adjustments, resulting in a 61% rise in testosterone and a cautious approach to iron dosing.

Key insights include the athlete’s target swim metrics: a 2,000‑yard continuous effort in roughly 110‑115 seconds per 100 yards without a wetsuit, and a 24‑minute 2K as a baseline for race‑day readiness. He stresses that elite triathlon success now hinges on meticulous planning; talent alone no longer guarantees podium finishes. The discussion also highlights the psychological hurdle of blood draws and the importance of mental resilience when confronting performance data.

Notable quotes underscore the philosophy: “Failing to plan is planning to fail,” and the comparison of his benchmark to world‑class swimmers, noting that even a 90‑second split in a 70.3 can dramatically improve winning probabilities. He warns against reliance on “cheater shorts,” wetsuits, or paddles as performance crutches, emphasizing that true improvement stems from disciplined, repeatable effort.

The implications are clear for competitive triathletes: systematic testing, precise biomarker monitoring, and strict swim pacing benchmarks provide actionable feedback loops that can shave minutes off race times. Athletes who integrate these practices are better positioned to meet the escalating performance standards of Ironman‑level events.

Original Description

Swim benchmark day.

Nothing fancy here—just a repeatable session that helps me understand where my swim fitness is right now.

One swim won’t win a race. Just like one workout won’t win a race. What matters is stacking consistent training over weeks and months.

In the middle of the session we also end up talking a bit about Mark Dubrick and training philosophy—how to approach intensity, how to keep workouts repeatable, and why consistency matters more than hero sessions.

Right now the focus is simple: build consistency again.

Train well.

Recover well.

Repeat.

That’s what actually moves fitness forward.
