In the early 1970s, several highly competitive 100-mile races had been held in England, but they were still only organized for  attempts to break British or world records. In 1975 another classic race was held, perhaps the greatest and most competitive 100-mile race ever held. It left one reporter speechless, witnessing something that he would never forget, watching some of the fastest 100-mile runners ever, and experiencing the sportsmanship of ultrarunning for the first time. This story must be retold.

In America, 100-mile races were being held, open to anyone who wanted to give it a try, even the naïve. In 1975, the annual Camellia 100 held in the Sacramento, California area was held for the fifth year.

But the oldest annual American 100-miler that tends to be forgotten, was the Columbia 100 Mile Walk held in Columbia, Missouri. In 1975 It was held for the ninth year. There had been 23 sub-24-hour 100-miler finishes in its history. But this was nothing compared to Great Britain. There, 100-mile walking races had been held annually since 1946, for 30 years, with more than 450 finishes in less than 24 hours.

Elsewhere, the Durban 100 held every-other year in South Africa, had been competed six times, with at least 33 finishers (only partial results have been preserved). In Italy, 24-hour races had been held every year since 1970 with 100-mile finishers. In 1975, a 24-hour race with many 100-mile finishers was competed inside the Soviet controlled iron curtain, in Czechoslovakia.
