He placed sixth at both the 2010 World Junior Championships in Athletics and the 2011 European Athletics U23 Championships. The 2012 Thorpe Cup saw him reach new heights in the senior division.
However, again he was ranked outside of the top three nationally and was not selected for the 2013 World Championships in Athletics. He regarded this as a good thing, saying: "We have got a really strong Decathlon squad in Germany and I am really happy about that.
We can learn so much from each other..I get an enormous amount from it".
