Toward a record-eligible sub-2-hour marathon: an updated integrative framework of Physiological, technological, and cognitive determinants.
Worth trying if it fits your goal and context.
ELI5
In plain language
Breaking the sub-2-hour marathon barrier under record-eligible conditions requires the coordinated contribution of physiological, biomechanical, psychological, environmental, nutritional, and technological factors. (narrative review; participants).
In this narrative review, the abstract suggests a positive relationship with Time-trial performance. Treat this as a signal, not a guarantee; confirm methods and context in the full paper.
Takeaways
What the abstract suggests
- • Study question: Breaking the sub-2-hour marathon barrier under record-eligible conditions requires the coordinated contribution of physiological, biomechanical, psychological, environmental, nutritional, and technological factors.
- • In this narrative review, the abstract suggests a positive relationship with Time-trial performance.
- • Population: participants.
- • Protocol cues (title/abstract): 6 mg • 2 h • 21 km.
Protocol
Protocol (as reported)
- • Intervention/exposure: pacing.
- • Dose/time/duration cues in abstract/title: 6 mg • 2 h • 21 km.
- • Outcomes: Time-trial performance.
- • Replication note: abstracts often omit adherence and timing; confirm details before changing training or supplementation.
Fit
Who it helps, and who should skip it
Who it helps
- • Athletes similar to the study population (participants) working on pacing.
- • Athletes who can measure Time-trial performance with a repeatable workout or time-trial effort.
Who should skip
- • If you have symptoms or conditions that make the intervention risky, get professional guidance.
- • If you’re near race day and can’t safely test, defer the experiment.
Methods
What the study actually did
- • Design: narrative review.
- • Population: participants.
- • Outcomes measured: Time-trial performance.
- • Protocol cues mentioned: 6 mg • 2 h • 21 km.
- • Source: PubMed PMID 41351755 (2025) — European journal of applied physiology.
Results excerpt
What the abstract reports
“It synthesizes multidisciplinary evidence to propose a conceptual model illustrating how physiological, mechanical, cognitive, and technological domains interact to constrain or enhance endurance capacity.”
Note: excerpts are short; for full context, read the paper.
Limits
Limitations & bias
- • Abstract-only summaries can miss critical details (population, protocol, adherence, and context).
- • Reviews and consensus statements mix protocols and populations; recommendations may not match your exact constraints.
- • If your context differs (elite vs recreational; cycling vs running), adjust expectations and be conservative.
- • This is performance information, not medical advice.
