The Log is on the other side of the monorail track, which you can reach by sprinting and jumping at the last second. I failed to jump across during my first attempt, so I found my own way across: I knocked the sign from above down onto the ground, pushed it slightly over the gap, then ran to the end of the sign and jumped, easily clearing the gap. This isn’t at all necessary, as it can be cleared with a standard sprint jump, I just wasn’t aware of this at the time
