After 20 challenges, 200,000 participants, 12 Twitter trends and over 2.5 million YouTube views, the One Direction ‘Save The 1Day’ challenge culminates this Thursday with an exclusive online album listening party for fans across the world.

The ‘Save The 1Day’ challenge began weeks ago when the boys lost their production laptop and it got into the hands of a hacker/gamer/mega 1D fan, 1DCyberpunk. Rather than giving it back, she decided to lay down a series of challenges to see if the Directioners could prove they are as big a fan as she is. If the Directioners win a challenge they get some of the laptop content back. Photos, videos, lyrics, the works!

So far 1DCyberpunk has had the Directioners making origami dolls of the boys, taking part in quizzes, doing complex maths sums and even dressing like her for Halloween. But it seems like Directioners are having a blast winning back the laptop content. Some are saying they run home from school or stay up late in different time zones around the world just to take part in the latest challenges.

Now with One Direction’s debut album about to launch, there is one final challenge before fans can hear Up All Night. 1DCyberpunk has challenged fans to unlock the listening party by taking part in #1DPartyRun, an online video race! Fans will upload videos of themselves or their 1D dolls running to the party and if enough entries are submitted they will unlock the party and arrive in time.

If fans are successful the Listening Party will go ahead tomorrow night.
