The Olympics always felt like it was going to be a watershed in men's sprinting. The only question was what lay on the other side. The world got a glimpse of what lies ahead in Lausanne on Thursday when Yohan Blake won the 100m in 9.69sec. Only Usain Bolt has run quicker. Twenty minutes later, Bolt was out on the track, winning the 200m in 19.58sec.
Both set meet records, but not for the first time, you suspect, in years and months to come, Bolt's performance was a little overshadowed by that of his young training partner. Blake destroyed a field which included three Olympic 100m finalists, leading from start to finish, accelerating away as the race went on. Blake's time cut six-hundredths of a second off his personal best, and left him tied with Tyson Gay as the second-fastest 100m runner in history.
Kirani James won the 400m in 44.37sec.
