My dad has done a half ironman and loads of triathlons (specifcally London and Blenhiem). It's not that hard if you like pain and have the right mindset and intention.. It was hard work watching them cross the finnish line and 50% keeled over, you should see the medic team they have!
Yeah I took some before pics, I'm *text deleted* post some after pics in 1 months time. It's a shame he didn't do some mega amounts of push ups too, his upper back is lacking important muscles to look sexy
