Understanding these changes can inform targeted training to enhance performance. In previous work, we identified two technique-based clusters of runners: the \u201cneutral pelvis\u201d and the \u201ctilted pelvis\u201d clusters. This follow-up study examined whether fatigue induces cluster-specific technique adaptations. Sixty runners (neutral pelvis,\n                    <jats:italic>n<\/jats:italic>\n                    \u00a0=\u00a032; tilted pelvis,\n                    <jats:italic>n<\/jats:italic>\n                    \u00a0=\u00a028) completed a treadmill run to exhaustion at 5% above their individual lactate threshold speed. Stride frequency, duty factor, trunk and lower limb kinematics were compared between clusters at the start, middle, and end of the run using a 2-way repeated measures analysis of variance (ANOVA). All runners reached exhaustion in \u223c20 minutes, covering \u223c5 km. Runners from the tilted pelvis cluster consistently showed greater trunk-to-pelvis extension, more pelvic anterior tilt and greater hip flexion, and a smaller duty factor compared with the neutral pelvis cluster throughout the run. Fatigue-related adaptations were similar across clusters: reduced stride frequency, increased duty factor, greater trunk flexion during stance, increased plantar flexion, and higher coordination variability (trunk-to-pelvis\u2013hip, hip\u2013knee, knee\u2013ankle) during swing. Although fatigue affected both groups similarly, the underlying technique differences suggest these adaptations may have distinct mechanical or performance consequences. Understanding such cluster-specific responses can help coaches tailor training and fatigue management strategies to individual running styles.\n
