I've been watching him his entire career, (Since he was playing for the Wales u20s as an Ospreys academy player) and the furthest I can remember was on the 10 metre line inside his own half for the Cardiff Blues in a league match. (I think it was against Munster, but don't quote me on that) That'd be around 60 metres.
from watching him, about 5 meters from behind the halfway line so quite far!
