By Davy Crockett For most elite ultrarunners, as they reach their mid-40s, their competitive years are mostly behind them. But for Ted Corbitt, his best years were still ahead of him, as he would become a national champion and set multiple American ultrarunning records. Read/Listen to Part 1 and Part 2 of Corbitt's amazing history as he became "The Father of American Ultrarunning." Perhaps Corbitt's most notable achievements in the sport of long-distance running was his groundbreaking work in course measurements. He said, “My initiating the accurate course measurement program in the USA is easily the most important thing that I did in the long-distance running scene.” He understood that “for the sport long-distance running to gain legitimacy, a system was needed to verify performances, records, and ensure that courses were consistently measured in the correct manner.” Learn about the rich and long history of ultrarunning. There are now ten books available in the Ultrarunning History series on Amazon Learn More Course Measurement Standards Obtaining accurate measurements for courses had been important for over 150 years. During the 19th century pedestrian era of ultrarunning, indoor tracks varied in length depending on the size of the arena. Professional surveyors and engineers were employed to measure the tracks down to the inch. This was important in six-day races as runners would circle the tracks thousands of times and massive wagers were made on how far runners would go. Mistakes were made at times. In October 1879, a couple weeks after the Fifth Astley Belt race held in Madison Square Garden, won by Charles Rowell (1852-1909) of England with 530 miles, the track was remeasured for another race and was discovered to be several feet short per lap which meant that Rowell actually instead covered 524 miles. The controversy resulted in a lawsuit because the error affected the distribution of enormous winnings earned by the runners. After that debacle, race managers were much more careful about certifying their tracks. In the 20th century, ultrarunning returned to road courses. With the introduction of the automobile, odometers were typically used. But those devices were rarely calibrated accurately as auto manufacturers liked to have them register more miles than actually traveled. Off-road course measurement was even more difficult. In 1959, a five-mile cross country course was used in the Bronx, New York. A careful remeasurement after the race discovered that the course was short by 490 yards. Another important example: As the famed Western States Trail was used by the horse endurance race, The Tevis Cup, in the 1950s, 1960s, and 1970s, and for the early years of the Western States 100 foot race, it later was discovered in the 1980s the course was not even close to 100 miles, it was no more than 89 miles, more than 10% short. It wasn’t initially a 100-mile race. John Jewell As Corbitt went to England in the early 1960s to compete in London to Brighton, he became acquainted with John Jewell (1912-2001), a founding member of the Road Runners Club in England. In 1961, Jewell wrote a paper describing the process of road race course measurement in England. He refined a method of using calibrated bicycle wheels for measurement. Jewell measured the London to Brighton course that Corbitt competed on. Corbitt was convinced that a method of accurate course measurement was needed for America’s long-distance races. He pointed out, “The U.S. has sent marathoners and walkers to the Olympic Games who thought they were in a certain time range, but who in reality were several minutes slower on full length courses. This is unnecessary since it is possible to measure courses accurately." He exported many of Jewell’s ideas, did his own research, and published a historic 29-page booklet in 1964, “Measuring Road Running Courses.” He evaluated all the typical methods of measuring courses and concluded ...
