The claim that records fall because belief falls first: once Bannister broke the four-minute mile, the barrier was exposed as psychological, and the floodgates opened. The founding parable of motivational speaking.
Documented
The seven weeks
Gunder Hagg's 4:01.4, set in Malmo in July 1945, stood almost nine years. Roger Bannister, a medical student paced by Chris Brasher and Chris Chataway, ran 3:59.4 at Oxford's Iffley Road on May 6, 1954. John Landy answered with 3:58.0 in Turku on June 21, forty-six days later. That August both men broke four in the same race, Vancouver's Miracle Mile. Twenty-three days after Bannister, Diane Leather broke the women's five-minute barrier in Birmingham, to a fraction of the coverage, because the IAAF did not even keep women's records at the distance.
Assessment: Every date, place and time is documented, and the clustering is real. What the clustering proves is contested by construction, since training methods changed at exactly the same time as belief did.
Stories
The mind is the barrier
The motivational canon took the story whole: the body was never the limit, the limit was a shared conviction, and one man running through it freed everyone. Sheldrake filed it as a candidate morphic-resonance signature, a threshold crossed once and then easier everywhere, which is the exact moment the sports story became a physics claim.
Assessment: As psychology the story is plausible and never falsified, since belief and method changed together. As evidence for memory in nature it is an analogy wearing a lab coat, which Sheldrake's own critics note he elsewhere insists on testing properly.
Interesting claims
The debunkers' record book
The plateau had boring causes. Hagg and Arne Andersson, the two Swedes driving the record down, were banned as professionals in 1946, and the war had frozen international competition just as the mark neared four. Franz Stampfl's interval training was a genuine methodological break. Landy had already run 4:02 three times in the 1952 to 1953 season. Bannister's race itself was an engineered artifact: pacemakers, a plan, a carefully chosen day.
Assessment: The materialist account is well documented and explains the timing with no barrier of belief required. The belief story survives because it is the more useful tool, not the better history, and the two get confused in every retelling.

Worth asking
The record book says war and interval training. The poster says belief. Which account of the four-minute mile actually makes people run faster?
