This video is further proof that anything someone can do on a two wheels, someone else will try it on just one. Extreme unicyclists Lutz Eichholz and Stephanie Dietze head into the Alps to take on the 3400 meter (11,154 ft) Mettlehorn on their single-wheeled bikes. They're both braver than I am, that much is certain.

Pulpit Rock in Norway is a 604 meter (1982 ft) cliff that overlooks Lysefjord fjord. It is a popular landmark that draws hikers from all over to take in its sweeping views. Today, you can visit the rock through this beautiful timelapse video, which is likely to inspire you to want to go and see it for yourself. It seems like a fitting way to end the week.

Way back in August I wrote a post about Reza Reza Pakravan and Steven Pawley, two long distance cyclists who were embarking on an epic ride from Nordkapp, Norway to Cape Town, South Africa. Their plan was to cover the 18,000 km (11,184 miles) distance between those two cities in just 100 days. Yesterday they completed that ride and they missed their target goal by just two days.

Reza and Steven faced all kinds of challenges as they rode through 14 different countries on their journey across Europe and Africa. Along the way they faced nasty winds, surprisingly bad weather and unexpected illness. The latter of those challenges was what ultimate prevented them from completing the ride in the expected 100 days. Despite all of the difficulties they had to overcome on their ride, the duo still only missed their scheduled arrival by two days. That is pretty impressive considering the number of miles they had to ride in such a relatively short time.

The video below was shot following their arrival in Cape Town yesterday. Not only did that mark the end of the expedition, Reza and Steven also announced that they had raised £20,000 ($32,375) for Azafady, a nonprofit that is working to build schools in Madagascar.

Congratulations to Reza and Steven on completing their incredible ride. In order to reach Cape Town yesterday, they had to average 176.5 km (110 miles) for 102 days straight. Those are impressive numbers indeed.

The Red Bull X Alps is a unique race to say the least. Competitors begin the event in Salzburg, Austria and must race through the Alps to Monaco, covering a distance of about 1000 km (621 miles) along the way. They can choose their own route but they can only travel on foot or paraglider, which means the athletes are typically climbing up snow-capped peaks, launching their paragliders and flying as far as they can go, before repeating the process on another mountain. The video below follows two-time defending champ Christian Maurer as he goes for his third straight victory in the race earlier this year. It is an amazing look at a very cool competition that few people know anything about. Great stuff and these racers are definitely in a class all their own.

Not all of the cold weather adventures are taking place in Antarctica at the moment. Case in point, the just launched Pole of Cold expedition that got underway last week which plans to cross Northern Europe and Siberia on a three-month long, 30,000 km (18,641 mile) journey to reach the coldest inhabited place on the planet in the dead of winter.

The three-person team on this expedition include veteran polar explorer Felicity Aston, mechanic Gisli Jonsson and filmmaker Manu Palomeque. The trio were the winners of a Land Rover bursary which provides funding for this expedition. They set out from the Royal Geographical Society headquarters in London and are now making their way through Norway, where they encountered their first bits of snow. Eventually the journey will take them into deepest Siberia however, where they will make their way to Oymyakon, which is widely considered the coldest inhabited place on the planet. How cold you ask? The thermometer once recorded a temperature of -67.7ºC (-89.8ºF). Now that's cold!

The journey will be a road trip of epic proportions. The route will take the team into some of the most remote places on the planet where temperatures will routinely plummet to dangerous levels. They'll have to deal with non-existant roads, plenty of snow and ice and a complete lack of infrastructure once they get out into the heart of Siberia itself. This will be a round-trip journey that begins and end in London, with a stop at the northernmost point in Europe and plenty of other cold places along the way.

The purpose of the journey is to explore cultural attitudes toward winter while also assessing how lifestyles are different in places that deal with extreme ends of the climate continuum.

You can follow the Pole of Cold team on their website and Facebook page.

There aren't many expeditions that you can go on that allow you to ski, snowboard, climb and surf, but that is exactly what the Wegge brothers got when they visited remote Bear Island off the Svalbard coast. The video below is a teaser for an upcoming film of their adventure, which judging from these two minutes of footage looks like it was filled will all kinds of interesting activities.

Thanks to my friends at the Adventure Journal for sharing this one.
