Japanese Record of straight 24 weekly sub-3s

Today, I ran the Kasumigaura Marathon in Ibaraki Pref., and my time was 2:52:47. It's basically flat course with some up-down, and the course of later half is along the Kasumigaura Lake. The participant number for Full Marathon was 14506. The total participant number was ~25,000.
As I achieved sub-3 today, I achieved straight 24 weekly sub-3s, and achieved 30th sub-3 in these 24 weeks. I'm  keep breaking the Japanese Record of straight weekly sub-3 as far as I know.
I don't know the World Record on this. If you know it, please let me know.
