These parameters deteriorate during prolonged exercise, and the ability to resist such declines (i.e.,\u00a0durability) is now also considered a marker of marathon performance. This study investigated the durability of markers of endurance performance (V\u0307O\n                    <jats:sub>2peak<\/jats:sub>\n                    , FU\n                    <jats:sub>LT<\/jats:sub>\n                    and RE), and whether the durability of these markers was associated with marathon performance.

Prolonged running impairs key physiological markers of endurance performance, and the degree of this deterioration, that is, durability, is associated with marathon performance. Marathon runners and practitioners should consider quantifying durability to complement existing physiological markers.\n
