6 x 400m Races in 5 Consecutive Days?

October is the 48th anniversary of the 1968 Summer Olympic Games in Mexico City. You’ve probably seen the highlights on Facebook.

Those Games will be best remembered by the Tommie Smith & John Carlos protest, but other track fans will remember sub 10 for 100m, sub 20 for 200m, and sub 44 for 400m. And let’s not forget the 8.90 (29′ 2.5″) Long jump by Bob Beamon. And, Richard Fosbury high jumping with his back to the bar in “only” 2.24m (7′ 4″)! (There are much more events to highlight)

400 meters, Then and Now

Not taking away anything from recent 400m greats, but today’s 400m has:

only 3 rounds, not 4 rounds
sometimes, there is a rest day between Semi Finals & Finals, as seen in 2015 World Championships
400m individual event is early in the 9 day program, with the 4×400 relays at the end of the program, and usually the very last event
You can name 6 members to the relay team, so in 2 rounds, you can save 2 fresh runners to only run the Finals (assuming you make the final! There are no guarantees, especially with the DQs as seen in Rio! 2016)

6 Races in 5 days… Whoa!
