And the one who held the record for two decades now, Brian Charles Lara, feels it's about time that someone breaks it. However, not just anyone but two Indian batters - Yashasvi Jaiswal and Shubman Gill, are the ones he thinks will surpass that number in Tests.
Brian Lara broke his (375) and Matthew Hayden's record (385) to become the first and only man to date to register 400 runs in an innings in a Test.
He did it against his favourite opponents, England, during the Antigua Test in 2004. No player since came close other than former Sri Lanka Mahela Jayawardene, who scored 374 against South Africa during the marathon stand with Kumar Sangakkara in 2006 in Colombo.
Twenty years later, Lara admits several players during the past two decades, including Virender Sehwag and Sanath Jayasuriya, challenged it, but none could break it.
However, he now feels two Indian batters have it in them to get past 400 in a Test inning.
"There were players in my time, who challenged, or at least went past the 300 mark - Virender Sehwag, Chris Gayle, Inzamam-ul-Haq, Sanath Jayasuriya. They were pretty much aggressive players," Lara said in a chat with The Daily Mail.
Although he also mentioned how just attacking batters have a chance at this shot, he mentioned the English duo of Zak Crawley and Harry Brook, who can also push for this record.
"How many aggressive players do you have playing today? Especially in the England team.
Zak Crawley and Harry Brook. Maybe in the Indian team? Yashasvi Jaiswal, Shubman Gill. If they find the right situation, the records could be broken - both of them," Lara continued.
Top-order batters have a chance
In today's age and game, several players have shown potential to become future greats in Tests, but going by what's happening around, only top-order batters look like someone who can get this job done.
Talking of Jaiswal and Gill - both have immense potential to score massive runs up front, with the young left-hander showing promise during the England Tests earlier this year.
With two tons, including a maiden double hundred and three fifties, Jaiswal topped the runs chart with 712 runs in five Tests.
However, Gill has shown his skill during several overseas series in the past two years, with his match-winning knock against Australia during the famous 2021 Gabba Test being the highlight.
