No no no no no. It's only a corporate logo.
I used to have a TVR which I loved, I'd longed to own one for years. I still wouldn't have it tattoo'd on me though. Nor would I have a Nike tick tattoo'd on me just because I've run in Pegasus trainers for more years than I can remember.
Seriously though, Tattoo's are a personal choice. If that's the sort of thing you go for then fair enough, but don't feel it's something you just 'must' do because you've raced an Ironman.
Give it 10 years and their solicitors will be chasing you down for breach of copyright anyway
