A race is usually a test of speed, but they can also be a test of endurance. Four drivers put their own endurance to the test as, over the course of more than a week, they cleared 100% of Gran Turismo 4 in a single, continuous marathon session.
Gran Turismo 4, released in 2004 for the PlayStation 2, is a pretty substantial game in terms of things to do, cars to drive, and courses to clear. Over the course of about nine days and change, four drivers—Tyler, Shawn, Jonah, and Paul-cleared every one of them, completing a 100% No B-Spec run that's been archived in this thread on the Speedrun subreddit.
"No B-Spec" is especially important, as that essentially means the drivers never let the game's internal AI handle the course driving. For every course in this run, someone was driving behind the wheel. While that might not seem daunting for an average race, Gran Turismo 4 has a variety of events, including three 24-hour races. They're literally 24 hours long.
In a FAQ on Pastebin, the four drivers estimated it would take "around 200 hours or a little over eight days." They took no breaks, playing straight through and swapping out drivers along the way to keep themselves fresh. As for why they're doing this, the drivers say they having nothing better to do, due to staying inside because of the ongoing COVID-19 pandemic, and point out they're the world's first. "Nobody has ever completed this category before—let alone routed it—and we figured we might as well be the first," they wrote.
This isn't the world's longest speedrun (pretty sure Baten Kaitos still holds the record), it's nonetheless a groundbreaking accomplishment. While they've been spending their quarantine time perfecting a world's first marathon run, I've been farming tarantulas and watching old Bon Appetit videos. Their record can, for the rest of us, at least be an example for what we can achieve with all this newfound free time.
And though there have been a handful of new Gran Turismo games over the years, this record in Gran Turismo 4 is likely to stay unchallenged for some time. That is, unless these four ever feel like picking up the wheel again.
