Lightning Bolt could go faster
World 100m record holder Usain Bolt could break the nine-second barrier if he gets a start as fast as that of his training partner, Yohan Blake, according to the former world 200m record holder Tommie Smith.
Bolt, who was beaten by Blake in both the 100m and 200m at this year's Jamaican trials, set his world record of 9.58 seconds at the 2009 Berlin World Championships.
He reduced his own world 200m record to 19.19 in Berlin.
"If he gets a Blake start, we are looking at 8.9, 8.88, three eights in the 100m," Smith said.
"If he gets a Blake start in the 200m and comes off the turn with that technique of his, he might really go sub-19."
Smith set a world record of 19.83 in the thin air of Mexico City at the 1968 Olympics, a mark which stood for 11 years.
On Smith's own reckoning, if he had not lost speed by raising his arms in triumph over the final strides he would have been pushing "18.9, 19.1".
"I thought I was great when I ran," Smith added.
"I didn't have the start and I didn't have the power.
"He's taller than me and more powerful. It scares you."
