Since having kids and then breaking my arm falling off a few years back, I've had no balls at all and I've barely ridden. As we were away and DD and I wanted a bonding session we booked a hack.
JESUS! Wales is REALLY HILLY!! 
I had a huge TB (a long way to fall!) which was admittedly really well behaved, and the going was a quite hairy!
I made the whole ride. I got to the end, was still on the horse, didn't cry and I had my eyes open for most of the time! 
GO ME!!
