Cortana, the most personal digital assistant on the market available on Windows Phone devices, and Danny MacAskill, world-renowned trials cyclist, have successfully completed one of the largest loop-the-loop challenges to ever be set on water. Danny rode round a monumental five-metre loop, illuminating the Cortana signature in front of one of London’s most iconic landmarks in the process.

Microsoft’s personal assistant Cortana is renowned for her instantaneous, intelligent and customised approach – she knows what you want and how to #makeithappen. With her proactive help, useful advice and instant solutions, Danny was able to fulfil a life-long aspiration seamlessly.

The loop-the-loop stunt adds to Danny MacAskill’s hugely impressive collection of challenges including the ‘Imaginate’ video, which has already received over 27 million views and ‘Way Back Home’ boasting over 32 million views.

Cortana acted as Danny’s personal assistant throughout his training for the activation, arranging his meetings, setting appointment reminders, playing his favourite music, warning for bad weather and finding maps.

“A career as a professional athlete can be quite hectic and as I prefer to spend as much time on my bike as possible – any help in organising meetings, travel plans and projects is great. This is one of the biggest set-ups I have ever ridden and the location is amazing. To have a five-metre loop floating on a barge is something surreal. I always look for new challenges and the chance to ride this massive loop with the help of Cortana is another achievement I can be proud of,” said Danny MacAskill.

“We’ve designed Cortana to be the most personal digital assistant – she adapts to individual personalities, learning by experience to become not only an instant reactive helper, but also an indispensable proactive influence. Danny’s London stunt is proof that she can enable even the most outlandish inspirational ideas to become reality,” said Adam Johnson, marketing director mobile devices at Microsoft.
