Last week's Guinness World Records Day celebrations (Thursday 9 November) saw thousands of records broken all over the globe, including at the Guinness World Records London HQ.

To honour the special occasion, we invited British sport stacker James Acraman to visit the office (for the third time) and attempt to break his record for the Fastest time to build a 171 cup pyramid.

He achieved a time of 1 minute 26.9 seconds in January 2017 – a record that earned the sport stacker a coveted spot in the Guinness World Records 2018 book.

With this tough time to beat, and the added pressure of having the attempt streamed live on Guinness World Records’ FacebookTwitter and Instagram accounts, the pressure was on for James.

Fastest time to build a 171 cup pyramid attempt

Official adjudicator Alan Pixsley gave James three attempts at breaking the record and he managed to better his time twice!

Watch the video below to find out the record time plus get some sport stacking tips from this serial record breaker:

James says he loves this particular cup stacking challenge because it requires "speed, balance and skill – and also looks visually spectacular".

He has been a dedicated sport-stacker for almost eight years now and practises his skills for up to two hours a day.

Launched to celebrate the day in 2004 when Guinness World Records became the world's bestselling copyright book, #GWRday 2017 saw thousands of people around the world attempting to secure their place in the history books.
