Since the 60s every event has improved significantly - except the 800. Take away the rarified air at Mexico City and this is even more evident.
Run a 1.44 today and you are still ranked well.
1.43.74 was the best time in 2007.
Snell ran 1.44.3 on grass in '62.
Ryun ran 1.44.9 (880 yards - around 1.44.3 for 800 m) in 1966.
Is it because this is the event where performance enhancing drugs have the least effect - steroids or EPO.
Let's look at Ryun's 880 yard World Record
He ran 1.51 in a preliminary heat less than two hours before it.
He wasn't going for the world record.
He won the race by three seconds
He had not run under 1.50 up until then.
The track was asphalt and was run at 4 pm in the heat of the day.
During the race he wanted to save himself for the mile race the next day and ran the first lap comfortably.
His 220 yard splits were - 26.2, 27.1, 26.1, 25.5 (probaby a 1.44.3 800 m)
The last 220 yards was the fastest. 800s just aren't run this way.
What if he went through in 24.2?
The last 200 should be the slowest not the fastest.
At 300 to go he took off and "kept looking around because I couldn't believe they were so far back".
