Mary King is the queen (geddit?!) of cross country! In the first part of PONY's cross-country masterclass with Mary (which you can read all about in September 2010 PONY Mag), gorge' dun Mr Skips takes to the water! He's being a bit strong, but Mary has some nifty hints for his rider, Poppy, for getting back a bit more control.

Scroll down to check out some cool cross-country video footage of the pair as they tackle all kinds of fence's in Mary's clinic, at Stonar School in Wiltshire...

Pssssst!

Can you spot Penny@PONY in the vid? Hint: she's doing the journo thing!
