Football (particularly enjoying going to watch the mighty Argyle play live along with the Green army , especially away, which I rarely do nowadays, not so enamoured with the Premiership.)
MotoGP
Athletics, particularly long distance running, I like the technical aspects of pacing and the mental strength thing, (a bit like boxing).
Cricket and Rugby sometimes (Internationals)
X Games, love BMX, Skateboarding, snowboarding, etc
Used to enjoy doing jujitsu but still love watching Boxing above all others.
