I coached Mark 5yrs ago and he made the trip up from Cornwall to work predominantly on jumping. He wanted to learn to judge distance for jumps as well as gaps too. I worked on his line choice and looking for this as well as his positioning for cornering too. I built the session up gradually so Mark could process the techniques required and explore the effect of them. By the end , he was jumping gaps to 9ft and also linking drops, gaps and turns together sweetly.
