When Dennis Kimetto lowered the marathon world record to 2:02:57 last fall, it renewed speculation about when we might see the first sub-2:00 marathon. It happened in Limerick, Ireland, on Sunday, but it took 105 runners to pull it off, I Love Limerick reports.

A group of men and women from all over Limerick came together to surpass the existing Guinness World Record for the marathon relay by running 1:56:54.

Each of the 105 runners ran 400 meters, except Gary O’Hanlon, who led off the relay with a 200-meter leg, since a track marathon is just under 105.5 laps of a 400-meter track. O’Hanlon later ran a 400-meter leg as well. The group’s average time per 400 meters was just under 66.5 seconds, roughly a 4:26 mile pace.

According to the Guinness World Record web site, a group from the United Arab Emirates ran 2:04:32 in March 2014. The new record is unofficial until all of the necessary evidence is collected, submitted to Guinness World Records, and has been reviewed and approved.

The Guinness record entails a large group running individual 400-meter legs. Sub-2:00 marathon relays have been run on the roads by world-class ekiden teams, in which six-person teams run legs of between 5 and 10 kilometers.

The group ran to raise money for Cliona’s Foundation, an organization that provides financial assistance to critically ill children all over Ireland. They are still accepting donations.

The relay was anchored by Liam Reale, once a national-class runner for Ireland, who graduated from Providence College in 2005.
