I've been away (13 years)

Hi Everyone-

I was a member here, and very active in the triathlon scene 2005 to 2012. Been doing life - kids are older - I have more time for myself - and I'm jumping back in. What did I miss? What is different since then? Different gear? Different mindset? Different sport? Different world?What will I be surprised by as I dip my toes in? (literally and figuratively) I defaulted to this community - it still looks pretty active - but Im sure there is another hot online community in Reddit, FB, etc.
