An early proponent of Fartlek training, HÄGG broke a total of 15 WORLD RECORDS during his running career [10 of them within just 3-months in 1942]!!!🔥
HÄGG’s prime form during the years of World War II extinguished any Olympic opportunities, but his Legend lives on; in fact he was the first athlete to run 5000m in under 14 minutes [a record that lasted 12 years!] and it also took several years before his 1945 Mile World Record of 4 mins 1.4 secs was beaten [by a certain Roger Bannister in 1954, becoming the first man to go sub-4]…🌟
