Double world record holder Usain Bolt has quelled speculation about a growing rivalry between himself and his training partner Yohan Blake, after the latter emphatically announced his arrival on the big stage with a World Championships 100m triumph, followed by a 19.26 clocking in the 200m, a time that is only bettered by Bolt's world record 19.19.

Bolt, who works out at the University of the West Indies alongside Blake under the guidance of Glen Mills and his Racers Track Club set-up, has welcomed the extra competition and credited claims of a growing split to controversy-seeking individuals.

"Everything's fine with me and Blake," Bolt said, before referring to the younger Jamaican as "The future of Jamaica. He's the one ... If he beats me, so be it. I don't want him to."

Bolt, who said that he would stop giving advice to the former St Jago athlete immediately after his 19.26 showing in Brussels, said he was only joking when he made that statement.

"I was actually laughing when I said it," Bolt said.

Blake's time was only seven hundredth of a second slower than Bolt's world record, but the more popular Jamaican is not getting overly concerned by abilities of his young friend.

"First they said it was Tyson Gay and then they said it was Asafa Powell. Then all of a sudden they say it's Blake," Bolt quipped.

"You can't focus your energy on one person and then they drop out," Bolt added. "What do you do? I focus on the seven people in the lanes with me."

Bolt, who was speaking in California, where he raised US$100,000 for his foundation, also seemed to have a change of heart as far as the false-start rule is concerned. Bolt jumped the gun in Daegu at the World Championships during the 100m final and was subsequently ejected by the race officials. He, however, stated immediately afterwards that he had no issues with the current rule, which states that should any runner who false starts at any point prior to a race, he or she would immediately be disqualified.

The 25-year-old now believes that it's time that the authorities consider a revisit of the previous rule, which sees the first false start charged to the entire field, with all subsequent false starts resulting in ejection for the offending athlete.

"They (IAAF) really should go back to the one false start and charge it to the field. It's easier. Somebody makes one mistake and everybody can relax," Bolt said.
