This is not my typical type of map. Very unlikely to make it with no respons on your first try, so use your first try to learn the route. This may have been considered "Platform" at one time.
Use the rooftops to navigate the first checkpoints. After that the route is fairly clear.
If for some reason you can't find the route, Download the record replay I've attached.
The replay is not my best time. Best time was 2:51:28, but when Nadeo changed the blocks I had to repair and revalidate this track (and most of my others too). This is just a validation run, but does show the route. Watch the beginning of the second lap to see an alternate route to CP-1.
Good Luck!
