On June 4, 1971 the Macon High School baseball team finished in second place at the Illinois High School Association championship tournament. Their unlikely run to the state tournament was documented in Chris Ballard's 2012 book, "One Shot at Forever: A Small Town, an Unlikely Coach, and a Magical Baseball Season." Brian Snitker, a member of that team, joined the Atlanta Braves as a player in 1977, was their third base coach, and as of 2014 is the manager of Atlanta's Class AAA Gwinnett Braves. 
Macon is the site of Macon Speedway, a 1/5 mile high-banked dirt oval track which has been in operation since 1946.
In 2006, the track saw a major decrease in spectator turnouts and the owner was having trouble keeping the track open. In early 2007, Macon speedway was purchased by NASCAR drivers Tony Stewart, Ken Schrader, and Kenny Wallace. Since their purchase, parts of the track have been remodeled, including new fencing all around and fresh painted grandstands.
