Last month, BAA announced a new lottery for runners who met their Boston qualifying marathon time but did not make the cutoff. They will put 1,000 spots aside for these runners, suggesting that the odds of getting in this way will be about 8 to 10%. But an interesting side effect of this lottery is … Read more
A couple of weeks ago, a new study was released that analyzed pacing data from the 2015, 2016, and 2017 Boston Marathons. The title, “Pacing strategy patterns and performance outcomes in marathon runners,” is interesting. But when you dig into the methodology, I’m not sure they actually measured and analyzed what they expected to examine. … Read more
I’m currently working on a longer article about age group winners at the World Major Marathons. I’d been exploring the data a bit, and a simple question came to me while I was out for my run this week: which of the races have the fastest age group winners? I was curious if one or … Read more

I usually reserve these deep dives for the Majors and a handful of other really big races. While Grandma’s Marathon is a big race, it’s not that big. But there were a few things that made this year’s race particularly interesting. It’s the 50th anniversary of the race, and it sold out in less than … Read more
The Boston Marathon Cutoff Time Tracker tracks the net change in Boston qualifiers from year to year and that is the main variable used to determine the projected cutoff time. But not all BQ’s are necessarily equal. Only some of those runners will actually apply to run Boston – and that conversion rate of qualifier … Read more
The Presidential Fitness Test is a core memory for many Americans, especially if you’re a millenial or Gen X. For decades, we participated in an annual ritual that included, among other things, a mile run. The standardized test was phased out in the 2010’s, but it’s been back in the news since the president announced … Read more
