The 2016 Summer Olympic marathons in Rio de Janeiro, Brazil, will be run on a course with a loop being run multiple times and we wanted to create something similar, said Tracey Russell, the CEO of Conqur Endurance Group, the trials local organizing committee.
It has a little bit of everything, said Tracey Russell, Atlanta Track Club executive director and Peachtree race director. The course is downhill through the first three miles, and then theres a tough climb through mile four.
