OLYMPICS champion, Usain Bolt said American sprint rival Tyson Gay "probably just hates my guts" because he has dominated major championships.

Bolt won both the 100 and 200-metres titles at the 2008 Olympics in world-record time, and helped Jamaica win gold and set another world record in the 4x100-metres relay.

A year later, he again set world records in the 100 and 200 at the world championships in Berlin.

"I think Tyson sits at home and curses me," Bolt told BBC radio.  "He just really gets upset because every time he runs fast, I run faster than he does. At the world championship he ran 9.71 and that's the fastest a US athlete has ever run and he was still cursing. So deep down I think he probably just hates my guts."

The 24-year-old Bolt hadn't lost an individual race in two years until last month, when Gay beat him in Stockholm in a 100-metre race.

"It's no stress. This year is not a cham-pionship year, this is my year off I would say, so it is no problem," Bolt said. "I am always ready, prepared and on top of my game (at the championships)."
Bolt says that he doesn't speak to the 28-year-old Gay away from the track.

"We are cool but we aren't the best of friends," Bolt said.
