While it's Friday night here, three Nike-sponsored athletes are up early on a Saturday morning in Italy. The company has made it a quest to break the two-hour barrier for a marathon run, as Lelisa Desisa, Eliud Kipchoge and Zersenay Tadese go for that 1:59:59 time on the F1 track at Monza. You can watch live on Twitter or Facebook right now (we're as shocked as you are that no network jumped to broadcast a two-hour run). They're running with a pack arranged for maximum aerodynamic efficiency while following a Model S (no exhaust fumes) to find an optimal pace at an average of 4:34 for each mile. Sure, it's no reusable rocket launch, but we'll follow along with this potentially amazing feat from the couch.

Update: In the end, they didn't quite make it, but Eliud Kipchoge finished in 2:00:25, under the IAAF world record time of 2:02:57 (this run is not eligible as a WR time).
