When I do a deep dive review of marathon results, I employ a variety of methods. The method that I use the most often is looking at split data. I look for missed splits, especially when coupled with a significant increase in pace over the portion of the course where the runner did not register a split.
I also look at a runner’s history to flag potentially suspicious results. Below is a perfect example of how I use history to catch cheating.
Looking at this result in a vacuum, nothing would have flagged it for review. The runner missed no splits, and ran a very consistent pace with a slightly negative split.
The most basic review that I do in looking at a runner’s history is to compare results with previous years. I have the data from the prior few year’s results from Philadelphia. My first task was to look at all runners with finishing times from both 2018 and 2017.
The runner above showed a 2017 Philadelphia Marathon time of 5:18:10. When I sorted the list by percentage variance between the two years, he was near the top of the list to review. It was at this point that I pulled up his race history.
The result was a huge outlier. The runner never approached this pace in any other races. At this point I was certain that someone else ran with the runner’s bib. The race photos were not immediately available, but they confirmed my suspicions. Below is the photo of the winner of The Male 60-64 Age group.
This runner will be reported to the Philadelphia Marathon, and further results will be flagged for review.

He’s aged really, really well!
I usually just read your articles and finish them confused on peoples motives. This one cracked me up. The expression on the 60 year old is so perfect 🙂
I’ll have what he’s having.
How pathetic.
His bib says “Maroon.” I can believe it.
Looks like he got it changed from green at the expo, thus the “maroon” sticker.
I used to use the ‘Maroon’ title for dumb people…akin to Bugs Bunny who was always saying “What a maroon.” I thought it was Bugs mispronouncing ‘moron.’ Turns out it’s actually a racial slur too. So be careful out there.

It’s also a slur on University of Chicago sports.
Bayesian, the maroon in question is pictured wearing a University of Pennsylvania singlet, yet not the bubble bee singlet the track and cross country teams wear
This guy just ran on someone else’s bib, check out winner of 75 AG in Philly, who appears to have deliberately cut the course. Probably just wanted his medal and didn’t think that 3.05 would be near AG world record!
Have him flagged. 2 minute pace for 2nd half. I believed I referenced his result in my initial article. Was giving the race a little time to clean the results. Planning a follow up article.
Actually, there was a different runner that was removed. This runner was not even in the initial results. Not sure how he got added. Looks like I have work to do.
