In 1978, Martin was selected by the U.S. Olympic Academy to be one of three representatives to the International Olympic Academy. Even before then, he had begun to compile a database of top-level men's and women's performances. His work has continued, and the list now tops 44,000 performances. This provides an unparalleled resource for his research on the use of mathematical modeling techniques to assess performance trends in distance running. And since 1989, he has been marathon statistician for the ATFS, taking over the role pioneered by coauthor Roger Gynn.
Martin lives in Decatur, Georgia.
Roger W.H. Gynn began documenting marathons in the late 1950s and is today one the world's foremost experts on marathon statistics. In this role, he was responsible for producing documentation on the marathon for the ATFS Annual, the definitive source for track and field performance statistics. Gynn resides in Watford, Hertfordshire. Table of Contents Chapter 1. Race Chapter 3.
