Is it true that hitting the wall during a marathon is inevitable for all runners?

No. While hitting the wall is a common phenomenon in marathon running, it is not inevitable for all runners, as proper pacing strategies, training, and fueling can prevent severe late-race performance collapse.

Verdict: REFUTED · 0 sources for, 3 against · Last checked

The analysis

The claim states that hitting the wall is inevitable for all runners. However, multiple papers discuss pacing strategies like even pacing and negative splits, and large-scale data analyses show that significant portions of runners successfully avoid severe late-race slowdowns or performance collapse. Therefore, the claim is refuted.
