Answer:
The route is handicapped accessible is the correct inference.
Explanation: To infer something from a text, it must be suggested but not explicitly stated. The passage explicitly states that the route is 10 kilometers, as well as stating the approximate time needed to complete it for fast runners. However, nowhere does the passage explicitly state that the route is handicapped accessible, but we can infer this to be true. Otherwise, wheelchair athletes would not be able to participate. Finally, the passage does not state that only wheelchair athletes complete the Peachtree - in fact, the next sentence says explicitly that "wheelchair competitors are not the only ones who compete at a world-class level."
