Hopefully someone has the time and expertise to take a deep dive in to this situation...Marathoninvestigation.com?
If he really ran those times, he deserves all the glory and accolades of an amazing series of results. But our sport, its records, and verified record setters deserve certainty regarding the integrity of official times.
Here are a few issues of concern for me;
1) He was originally lauded by Runners World in 2015 as one of its Masters Runners of the Year for his 2:52:33 finish at the 2014 California International Marathon (
https://www.runnersworld.com/advanced/a20848209/2014-masters-long-distance-runners-of-the-year/
). But this results was later scrubbed from the official results of CIM when it was discovered that Meza had missed several timing mats AND apparently did not appear in race photos throughout the course. There is another discussion thread on Letsrun that mentions this situation.
2) A quick search of various results shows that Meza ran solid times for his age while he has in his late fifties and early sixties but nothing like the times he has been posting since the 2014 CIM (at times age grades above 95%!).
3) I did a somewhat thorough exploration of his 2017 and 2018 Long Beach Marathon photos. I found no photos on the back side of the course. I am familiar with this race. If you run that fast, you are alone on the back side of the course. Race photographers would have many photos of you. Other racers of his speed in those same races have dozens of photos throughout the course. He does not.
4) Now somewhat obsessed I checked out his LA Marathon results from the year of the CIM controversy. Very strange. He ran a 25:01 5K from 15K to 20K...then followed it up with AN 18:34 FROM 20k TO 25k. Again, I found no photos of him in the middle section of the course. He reappears in photos late in the race.
If the guy is setting world records, he deserves the praise and glory. But based on the CIM DQ in 2014, I think race officials should triple check their video footage or any other technology they have available to verify his performances since they are being touted as World Record setting performances:
