The two weeks trip to Siurana turned out to be a very successful one. After a couple of days of working on „La Rambla“ David could finally tick his first 9a+ ever. And right before leaving he finished the trip with a quick ascent of „La Reina Mora“, just next to La Rambla.

The trip to Catalonia was originally planned together with Ruben over New Year. But just before David got a foot injury which made it impossible for him to go. So he had to shift his climbing in Catalonia to February.

The main objective of the trip was to send La Rambla. In January David started to train for the upcoming bouldering season. Together with his coach Urs Stöcker he put up a new training plan in Zurich. Since the trip to Catalonia was actually planned earlier he didn’t train his endurance specifically. Instead Weiterlesen

Ascending “Action Directe” in the past and today

Wolfgang Güllich and Action Directe

With the first ascent of Action Directe in Frankenjura Wolfgang Güllich introduced a new dimension to climbing. During the years before, he had already revolutionized the difficulty levels. In 1984, he climbed the worldwide first 8b, “Kanal im Rücken” in Altmühltal. And in 1987, he also sent the world’s first 8c, “Wall Street”, in Frankenjura.

Taking difficulty to the next level in 1991, Action Directe became the test piece for the world’s climbing elite. At first Güllich assessed it UIAA XI, corresponding to 8c+/9a on the French scale. But then, during the following years, the climbing community agreed to make it a gold standard for the 9a level. Even today it is considered a very special route. Many world class climbers found it a hard nut to crack.

However, Action Directe might not have been the first 9a. Weiterlesen

We hope you also like the short article and the pics down below. They were originally published on the Hompage of the Escaladrome. We have translated the text into English as we believe it gives a good summary about our climbing achievements in 2016.

Let’s crush together in 2017!

From North to South and setting high



By Simon Lenke, David Firnenburg and Susanne Lieberknecht

Despite their young age, David and Ruben Firnenburg already belong to the climbing elite. No matter if it is bouldering or sport climbing, on rock or at competition, their name is often ranked top in the end. In recent years, the two native Hanoverians have achieved national and international success in climbing. Weiterlesen

Between lecture room, competition and rock

We’ve contributed our first article to the thecircuitclimbing.com below which is run by Eddie Fowke. He is a well-known and very friendly photographer and writer in the climbing scene and travels to almost every IFSC World Cup around the world. He’s a friend to every athlete in the circuit of rock and competition climbing. We are happy to work with him more often from now on!

If you like the article, spread the word so that everyone can benefit from our thoughts about the dual task of combining performance climbing and education in life. There are more articles about more topics to come!

Anyone who wants to study psychology at the University of Zurich (UZH), has to undergo a packed program with a year-round average of 40 hours per week or sometimes even 60-70 hours during the lecture period – and this within the confines of a public university where there is neither integration nor support of the sports system or athlete’s commitments. This sets a pretty tough schedule for athletes like David where competitive sport training often depends on free space and individual design of the study course, and where training starts to amount to a full time job. “In fact the first year at the UZH in psychology is a screening year. Virtually, they want to clear out every second student. That’s what here is called the assessment year“, David explains. Weiterlesen

“The Fine line”

Santa Linya in Catalonia is a very impressive sport climbing destination. Not only because of the steep power moves in the big cave and the spectacular shots in this film by Hening Wang. It´s also because of the many falls, frustrations and failure that are behind a sucessful climb. Ruben is showing this fighting spirit in “Seleccio Natural” (9a) that has turned out to be his hardest project up to now even though it is not his first route in the grade. And by keeping working on it he fires all our inspiration for hard climbs.

The last stage of the German Lead Championships took place at Neu-Ulm (Bavaria) last Sunday. As last year, this year’s championships consisted of 3 competitions, in Germany known as German Lead Cups. The first cup was hosted at the brand new DAV climbing gym at Munich Freiman and the second at a rather old but gold climbing gym at Frankenthal in Pfalz close to Mannheim. For us two it was a nice series with various challenges because the Cups had different route settings. Weiterlesen

In the beginning of October we’ve spent three days at Swiss Rätikon for some multipitch climbing. Rätikon to climbers is well known for its hard alpine climbs on outstanding limestone and the surrounding beauty of mountain nature. It is located up in the mountains on an altitude above 2000 meters and is divided into two parts, a Swiss and an Austrian but the walls are mostly south facing so you predominantly climb on the Swiss side. The closest village is called Schuders consisting of only a handful houses. This time we were climbing at the Schweizereck in the region around Grüscher Älpli besides the other parts of the wall such as Kirchlispitzen (known for routes like Silbergeier, Unendliche Geschichte and WoGü), Drusenfluh and Drusentürmen.

David was supported by Axel Hake (IG Klettern / DAV-Landesverband Niedersachsen).  Weiterlesen

In this 10 minutes film we get portrayed talking about how everything started, our passion for climbing, the experiences we made, training, competition and rock climbing and many other things. During the film we climb “The Essential” (9a) in Frankenjura while testing Vertics.Sleeves, one of our hardest co-ascents on a rope to date. We don’t want to say too much here. Follow the link below and enjoy ;-) Cheers David & Ruben

New Base Line (8B+) in Magic Wood

This April I went to Magic Wood for a couple of days to work on hard boulders I couldn’t finish the last time I was there. On the very top of my tick list there was New Base Line, a boulder problem which was originally put up by grand master Bernd Zangerl as an 8C. Meanwhile it has seen several attempts by the world’s best boulderers and got downgraded to 8B+.

It is not only hard. It looks also fine. A noble crack line running from right to left with a slight rise through an overhanging wall. In the middle of the wall above the crack line there are nicely shaped crimps and side holds heading up to the top edge. It is just perfect. A dream boulder. This is probably why it is supposed to be one of the best in the world. Weiterlesen
