Welcome aboard, Ges (I was excited to meet him too, but don't tell him, it'll go to his head

)
I'm very new to this myself, but HR training has been good - I like the precision of knowing how hard I should be (and am) working. Not sure about even getting to z4 on the bike, though. Even z3 felt pretty hard to me ...
Ironman, then, eh? 2013, 2014???
