MOSCOW, Russia — Usain Bolt believes it’s going to be hard to break the men’s 4x100m relay record achieved at last year’s London Olympic Games.

In London, the quartet of Nesta Carter, Michael Frater, Yohan Blake, and Bolt combined for the first sub-37-second clocking, 36.84 seconds, to erase the 37.04 mark Carter, Frater, Bolt and Asafa Powell set at the Berlin World Championships in 2009.

Asked if the Jamaican team, without Frater and Blake, can lower the record, Bolt replied: “I can’t answer that. I will always do my part.”

He added: “As long as everybody does their part, we have some good athletes, some good competitors, so hopefully we can get the baton around, get it around quickly, and hopefully it will work out, but it’s going to be hard because we kind of put the record at a certain level.”

Meanwhile, the superstar sprinter he is here to win both sprints and is happy with his lastest training sessions.

“Everything will come good together,” he said, while adding yesterday’s workout was “on my starts and it felt good, so when everything comes together you may never know (what might happen).”
