Ulrike Meyfarth at just 16 years of age when she won her first of two Olympic titles over an equal WR, doubling as a WJR, and OR of 1.92 in the HJ in Munich in early September 1972. Of course, there were no official WJRs at the time.

Unbeaten over the distance this season, Felix. Behind, Debbie Ferguson McKenzie comes through to grab a late bronze in 22.41 with Muna Lee fourth in 22.48 secs.

Let's recall @allysonfelix as she comes off the bend slightly behind Veronica Campbell-Brown and shifts up gear to sweep past and away down the home straight for a commanding record third World title in 22.02 to 22.35 over the women's 200m (-0.1) in Berlin 16 years ago today

Arguably better than her SB of 22.17 in Memphis (1.2) in mid July and she picked up a few other notable scalps in the process. She was also a close runner-up to Shericka Jackson in 22.21 to 22.17 (SB) in Silesia (-0.3) four days earlier.

Nice win for Olympic bronze Brittany Brown, her first in a final race this season, from the middle in 22.23 over Favour Ofili in 22.31 and Marie Josée Ta Lou-Smith in 22.37 (SB) over 200m on a wet track and into a headwind (-0.5) in Lausanne yesterday

Matt Centrowitz took the race to his strengths from inside in a late burn-up of a roughly 50.6 last lap to earn the Olympic title in 3:50.00 over 1500m, first by a US miler in 108 years, nine years ago yesterday

Having also beaten Marlies Göhr over 100m in similar manner earlier in the programme for a fine sprint double in a night to remember. Pam Marshall takes third in 22.55 some way behind in a strong field by the way.

Let's watch Valerie Brisco-Hooks as she makes a fabulous transition off the bend slightly behind Marita Koch and sears past the WR holder down the home straight for a sensational win in a fast 21.98 (SB) to 22.19 over 200m against a -1.1m/sec headwind in Zurich 40 years ago today

RT @LsabreAvenger: Ryan Crouser produced three PBs and WLs of 22.22 at his second, 22.26 at his third and 22.52 at this fifth, the latter d….

RT @LsabreAvenger: His full series were 21.15, 22.22 (PB, WL), 22.26 (PB, WL), 21.93, 22.52 (PB, WL, OR), 21.74. Joe Kovacs earned silver….

Interestingly, Nelson topped qualification at an almost identical 21.15 earlier in the day.

Adam Nelson opens up out to a solid 21.16 in the first round which, retrospectively, earned him Olympic gold in the SP in Athens 21 years ago last Monday

RT @LsabreAvenger: Let's watch Renaldo Nehemiah as he gets off to a cracking start and blazes through over the sticks, challenged all along….

RT @LsabreAvenger: Nehemiah, of course, beat 13 secs first time in any conditions in a windy 12.91 (3.5) in Champaign (IL) in early June 19….

Pre-race WR holder Maricica Puică, Olympic champion over 3000m, also beats her own marker in an AR of 4:17.33 as runner-up and Zola Budd gets a NR and WJR of 4:17.57 in third.

Splitting a sound 4:00.51+ at 1500m en route to her new landmark for that matter. Decker was actually the very first woman to beat the 4:20 barrier in a WR of 4:18.08 in Paris three years earlier.

Let's watch Mary Decker as she takes it on at 800m to force the pace and contains holder Maricica Puică outside her round the last lap with aplomb before pulling away in emphatic fashion over the last 50m to win in a WR of 4:16.71 over the mile in Zurich 40 years ago today
