Question: What style of running also known as 'natural running', practiced in parts of Africa and Latin America was championed by South African and Great British athlete Zola Budd?

Barefoot running, also called "natural running", is the act of running without footwear.  With the advent of modern footwear, running barefoot has become less common in most parts of the world but is still practiced in parts of Africa and Latin America.  In some Western countries, barefoot running has grown in popularity due to perceived health benefits. <SEP>  She competed at the 1984 Olympic Games for Great Britain and the 1992 Olympic Games for South Africa, both times in the 3000 metres.  In 1984 (unratified) and 1985, she broke the world record in the women's 5000 metres. Zola Pieterse ("née" Budd; born 26 May 1966) is a middle-distance and long-distance runner.  She was also a two-time winner at the World Cross Country Championships (1985–1986).  Budd's career was unusual in that she mainly trained and raced barefoot.  She moved with her family to South Carolina in 2008, and competes at marathons and ultramarathons.  She volunteers as assistant coach at Coastal Carolina University in Conway.  Her mile best of 4:17.57 in 1985, still stands as the British record. <SEP> The Great South Run is an annual 10 miles (16.09 km) road running race which takes place in Portsmouth, United Kingdom providing an intermediate distance between the ten kilometre and the half marathon (21.097 km) runs.  Launched in 1990, it is part of the Great Run series created by former British athlete Brendan Foster.  It was originally held in Southampton, but the race moved to its current course after the first edition. <SEP> Born in Blood and Fire: A Concise History of Latin America is a book by John Charles Chasteen, professor of history at the University of North Carolina at Chapel Hill.  Chasteen covers the history of Latin America from 1492 to the present with an integrative approach that follows a chronological framework.  The book is divided into chapters that address themes that were common throughout Latin America, such as colonialism, independence, progress, neocolonialism, nationalism, and revolution.  Other themes that frequently come up in the book include issues of race, ethnicity, and class as well as the formation of republics.  A timeline is provided at the beginning of the book; and various maps, photographs, and images are used throughout the book.  "Born in Blood and Fire" was originally published by W. W. Norton and Company in 2001.  Three other editions have been published since, the most recent in 2016.  Later editions include updates and expansion of colonialism, nationalism, the Cuban Revolution, and current political and economic issues.  W. W. Norton and Company published Chasteen’s companion reader entitled "Born in Blood and Fire: Latin American Voices" in 2011.  This book includes narratives from a variety of sources that illustrate life in Latin America during the last six centuries.  Many of these excerpts from books, essays, and newspaper articles were translated by Chasteen.  Other books by the author include "Americanos: Latin America’s Struggle for Independence", "Heroes on Horseback: A Life and Times of the Last Gaucho Caudillos", and "National Rhythms, African Roots: The Deep History of Latin American Popular Dance".  Chasteen is also known for his translation of Tulio Halperin Donghi’s "The Contemporary History of Latin America".
