Do I have to go fast and upsidedown?
No. On the first two spans you will travel fairly slowly and in pairs, giving you plenty of time to explore the canopy. From Platforms 3-4 you fly fast and solo, and from 4-5 you fly upsidedown, if you dare! The guides control the course, so they can limit your speed if you prefer, and only you can flip yourself upsidedown so it is completely optional. Q.
