I believe this is a community challenge and should unlock once the time finishes. Simply start the game, jump around some with the
button and you should get credit for this.
This counts the progress from everyone that is playing and connected online, so you really shouldn't be worried about the community hitting the total.Update!
Please discuss the challenge in this thread on TA:Made a thread on the Saints Row site about the community challenges
I've got one reply from the devs so far.Update v2!
It should have unlocked for everyone.
