It is incredible to see how a man with just 26 years does this!! Neither trekking nor just climbing, otherwise, running! The Swiss mountain-runner ran up five 4,000-metre peaks within seven hours and 45 minutes. Breaking thus his own record. What a long way! He did the crossing for the first time in 2013, taking just over nine hours to do it.
In the link I have seen the amazing images of the wonderful landscape that he saw during his adventure in the Swiss Alps.
I have done the exclamation exercise and I have had just three errors. (:
