Which of this applies to you?

Answering these takes the parts that are not for you out of Cycling Merit Badge. Nothing is required, nothing is kept on the server, and nothing is ever hidden because a question went unanswered. A step that might apply to you stays on the list and is marked.

Requirement 6: road, or trail and mixed surface?

The badge asks for ALL of one option. They differ in distance, in the safety test, and often in the bicycle, so this is worth settling before you ride anything that counts.

Road biking only: how will you do the 50 miles?

Only asked if you are taking Option A. Either way it is 50 miles inside eight hours; the difference is whether you plan the route or ride somebody else's.
