On July 12, a 23-year-old world record will be in serious jeopardy.

The women's Monaco mile, renamed the "Brave Like Gabe Mile" in the late Gabe Grunewald's honor, is absolutely stacked as its top headliners have run sub-4:15: The Netherlands' Sifan Hassan (4:14.71 PR), and Ethiopia's Genzebe Dibaba (4:14.31 PR), who ran the indoor world record, 4:13.31, in 2016. 

In a meet known for favorable racing conditions and a historically fast track, the world-record 4:12.56 that Russia's Svetlana Masterkova ran in 1996 will certainly be in play once these women toe the line. 

The field will also benefit from the presence of Kenya's Beatrice Chepkoech, who obliterated the 3000m steeplechase world record at this meet last year in 8:44.32. She hasn't ever raced the mile, but owns a 4:02.21 1500m PR from 2018. 

Dibaba and Hassan are also no strangers to setting world records in Monaco—Dibaba set the 1500m world record, 3:50.07, at Herculis in 2015, and Hassan recently ran the 5km world record, 14:44, on Monaco's roads in February.

Adding to the intrigue, both women are fresh off running the fastest 1500m race the world has seen in years at last week's Rabat Diamond League meet, which delivered seven sub-4:00 performances and the world's best time since 2016 as Dibaba won with a 3:55.47 world lead, followed by Hassan, who turned in a Dutch-record 3:55.93 PR.

There couldn't be a more fitting setting for the Brave Like Gabe Mile. Grunewald, who dedicated herself to racing to her full potential no matter the circumstances, ran her 1500m PR, 4:01.48, in Monaco in 2015.

Today, Grunewald would have been 33 years old. 

The men's 1500m is shaping up to be quite the intriguing event, as well—defending world champion Elijah Manangoi,  2016 Olympic champion Matthew Centrowitz, and indoor world record-holder Samuel Tefera announced their entries today.
