PURPOSE
To compare finish times across WMM races for Boston, London, Berlin, Chicago and New York Marathons.
METHODS
Race times of the top 10 male and 10 female finishers were analyzed from 2005 to 2014 using the high-performance mixed linear model procedure in the Statistical Analysis System. Venue-to-venue comparisons, as well as comparisons between Boston and other WMM races, with and without factors of temperature, humidity and altitude change were examined.
RESULTS
Performance from 2005 to 2014 in the WMM races was found to improve at a rate of ~1% each 7 years. Despite its higher variability, comparison between Boston's estimated mean finishing time and all other venues revealed moderate positive differences, indicating the Boston event to be typically slower than other venues.
CONCLUSIONS
Across the 10-year study period, performance times improved ~1% each 7 years for both genders for the WMM, with the Boston Marathon being slower on average than other WMM venues. Weather rather than course metrics appeared to impact performance times most.
目的
比较波士顿、伦敦、柏林、芝加哥和纽约马拉松赛在世界马拉松大满贯赛事中的完赛时间。
方法
使用统计分析系统中的高性能混合线性模型程序，分析了2005年至2014年男女前十名完赛者的比赛时间。研究了不同赛事之间的比较，以及波士顿与其他世界马拉松大满贯赛事之间在考虑和不考虑温度、湿度和海拔变化因素情况下的比较。
结果
发现2005年至2014年世界马拉松大满贯赛事的成绩每7年以约1%的速度提高。尽管波士顿的估计平均完赛时间与其他所有赛事相比变异性更高，但仍显示出适度的正差异，表明波士顿赛事的速度通常比其他赛事慢。
结论
在为期10年的研究期内，世界马拉松大满贯赛事中男女成绩每7年提高约1%，波士顿马拉松赛的平均速度比其他世界马拉松大满贯赛事场地慢。天气而非赛道指标似乎对成绩影响最大。
