The purpose of this study was to analyse and compare pacing profiles of senior men and women competing in the 2017 World Cross Country Championships. Finishing and split times were collated for 118 men and 81 women competing over the newly introduced race distance of 10 km (five laps of approximately 2 km). Athletes were grouped according to finishing time, and changes in pace measured using lap times, except between Laps 1 and 2 because of a shorter first lap (times relative to the winner were used instead). Within both men's and women's races, groups slowed during the early stages, but then either sped up or maintained pace during the last lap. There were few differences between groups with regard to overall pacing profiles, or between sexes. The men's fast finish contrasted with slower finishes found in previous editions (over 12 km), and the degree to which women were slower than men (approximately 12%) was very similar to track racing and showed the decision to equalise the distances run by both sexes was sound. As in other distance events, athletes are recommended to try to achieve an even pace throughout, an approach that proved beneficial to both gold medallists.
本研究的目的是分析和比较参加2017年世界越野锦标赛的老年男子和女子的配速情况。收集了118名男子和81名女子在新引入的10公里比赛距离（约2公里的五圈）中的完赛时间和分段时间。运动员按完赛时间分组，用每圈时间测量配速变化，但第1圈和第2圈之间除外，因为第1圈较短（改用相对于冠军的时间）。在男子和女子比赛中，各小组在早期阶段速度减慢，但在最后一圈要么加速要么保持配速。各小组在总体配速情况方面，以及男女之间，几乎没有差异。男子冲刺阶段较快，这与之前几届（超过12公里）较慢的冲刺阶段形成对比，而且女子比男子慢的程度（约12%）与径赛非常相似，这表明使男女比赛距离相等的决定是合理的。与其他耐力项目一样，建议运动员在整个比赛过程中尽量保持均匀配速，这种方法对两位金牌得主都很有益。
