To put this into context, I think the video that is being referenced is by Durian Rider, nutter from Adelaide in Australia who has made a big deal about exclusively eating bananas. He and his (nutter) girlfriend made the video about the "toughest climb" in the world, which is purportedly in India. I believe she was demonstrating her way of refuelling on the ride. She is, however, very slim and obviously does ride a bike a lot.

Personally, I couldn't stomach the sickly sweetness. Full horsepower Coca-Cola is about my limit (and it's been a ride saver on randonnees on more than one occasions for me).

Maybe they were also taking the mickey. Who knows. And frankly, who cares.
