Lap-by-lap (interlap) pacing was analyzed using a 1-way ANOVA for mean time and mean velocity.

Within each lap, a high degree of oscillation in velocity was observed, which broadly reflected changes in terrain, but high-resolution data demonstrated additional nonmonotonic variation not related to terrain.<\/jats:p><\/jats:sec><jats:sec sec-type=\"conclusion\"><jats:title>Conclusion:<\/jats:title><jats:p>Participants adopted an even pace strategy across the 5 laps despite rapid adjustments in velocity during each lap. While topographical and technical variations of the course accounted for some of the variability in velocity, the additional rapid adjustments in velocity may be associated with dynamic regulation of
