Alan Jones was born in 1937 in Ridley Park, Pennsylvania. He became a runner at Ridley Park High School, Pennsylvania and continued running competitively at the Pennsylvania State University (Penn State). In 1971 he invented the Jones Counter that is used to measure virtually all running race courses in the world.
He began timing running races in 1970 and developed the program RunScore which is used to time running races and triathlons. In 2019, the RunScore program was sold to Race Roster in London, Ontario, Canada.
In 2005, he created age-grade tables to allow one to evaluate a running performance based on the time and the runner's age and gender. These tables were updated in 2010, 2015, and 2020 based on newer performances. A website created by Howard Grubb's provides an age-grade calculator[1]. The tables can be accessed on GitHub. The method used in developing the tables is documented at the GitHub site.
