Agree with you on so much here. 
I have now run two 10ks and a few 5ks. I did my first Tri (spring tri: 400 meter swim, 12 mile bike, 5k) last year, and I must tell you it was the most rewarding feeling I've ever had. I absolutely loved it - way more than just running alone.
And you're absolutely on point about John and normal.
