The Marathon Project, featuring many of the best marathon runners in North America, takes place this Sunday. There's a lot at stake on the 4.26-mile loop in the Arizona desert: Olympic dreams, big breakthroughs and maybe even an American marathon record?

Hosts Alex Cyr and Michael Doyle have been heavily covering every aspect of the race all week long in what we've dubbed "Marathon Project Week." In this pod, they break down all the key storylines, big numbers to watch out for, what the weird course is like, what went into putting on this Pandemic-era race, how to watch and who we think will win.

Be sure to follow us live on race day, starting at 9:30 a.m. ET. We'll be doing a live video podcast on YouTube, Facebook and our Twitter feed, covering the event through the whole race.
