The two completed the challenge and set the record at 7 hours, 29 minutes, and 46 seconds.
The attempt has been made before but nothing has been officially recognized until now.
It will be up to the Guiness World Records to decide if they made the cut.
Along the way the two had to take photos and document each with a time stamp in order to prove they succeeded.
They arrived to Alewife Station on the Red line around 4:45 a.m. this morning and completed the entire line in 90 minutes.
