Was looking on the TAR5 website and the info on it... look at this:
Two pre-determined legs have one FAST FORWARD, which allows the Team that completes the FAST FORWARD task first to proceed directly to the next PIT STOP without having to do any further tasks, including DETOURs or ROADBLOCKs, on the way. The trick is that only the first Team to find and complete the FAST FORWARD on the leg may use it; any subsequent Team that finds it will have wasted their time and must go back and complete all tasks. In addition, a Team may claim only one FAST FORWARD during the entire race.

Only two FF's in the entire race... should make competition for it really interesting.
