The previous post formatting didn't come out quite right, so I'll try again.

The topic here is racing a marathon on limited mileage. The paragraph Richard_ posted tells us two things, both of them meaningless in terms of this topic: One, that three world-class marathoners managed to break 14:00 for 5K and/or 8:20 for 3K and/or 4:00 for the mile -- not only unsurprising but a virtual given; and two, that the entire group of runners studied, not the marathoners alone, averaged 50 to 60 miles a week. I'd bet good money that this average resulted from the 17 non-marathoners putting in around 50 to 55 miles a week while the three marathoners dis considerably more than that.
So until Richard_ can provide training logs or credible testimonials regarding the training of Yawa, Sinqe and Mtola demonstrating that the members of this trio all ran low mileage, he'll remain enmeshed in his usual biased and nonsensical babbling.[/quote]
Quoting from the study:
"Despite comprising only 20% of the competitive distance runners in this country, black South Africans dominate all distances, usually filling equal to or greater than 90% of the top finishing positions in races from 5 to 56 km...
In contrast, white runners dominate the shorter middle-distance running events in this country. Thus, 42 of the 50 fastest 800-m and 41 of the fastest 50 fastest 1650-m (1-mile) times have been recorded by white South African runners...
Accordingly, the aim of this study was to further examine the possible mechanism(s) underlying an apparently superior running performance of black South African runners in races greater than 5km...
To ensure only the very best white and black South African athletes were included in these investigations...
Eleven black and 9 white runners qualified for the study on the basis of the personal best time achieved within the competitive season during which they were studied...
Among the black athletes studied were four of the five all-time best performers over 10,000m in South Africa, the South African champions over 5,000 and 10,000m and the world's two fastest performers in the half-marathon at that time.
...the athletes...were interviewed to obtain details of their training regimens. Each athlete's weekly training program was analyzed for the 8 weeks before each important race. Particular attention was paid to daily distance run, running speed, total running time per day, hill training, sprinting, gymnasium exercise, and details of fartlek, interval, and other speedwork sessions."
According to table 2 in the paper, the black athletes averaged about 92 km per week of running (SD of about 20km per week) while the white athletes averaged about 84km per week per week (SD of about 30km per week).
Based on the above data, your suggestion that the marathoners ran much more mileage than the other athletes appears to be inaccurate.
