We breed them tough in Deeside - and they all get used to bouncing over that sort of tough forest grot at an early age! Also they don't know the meaning of fear at that age...
PS Shooting Greens should really be tried at night when the bracken isn't fully down - its true glory is revealed.
Haha - it was too tough for me in daylight and no bracken!!
Not sure I'd want to experience it's dark and brackeny side! ;-)
...but if you can keep going for 70 minutes in that place its got to be a positive. And I'm sure you are glad you didn't take 25 seconds longer :-)
... 25 seconds longer would've ruined my day!!!!
