I am/was mostly a runner. Had serious injury problems in the late 90's and all I could do was cycle. I ended up at a LBS and asked for a 'good bike' that I could ride competitively if I chose to do that. I ended up with the Bianchi EL-OS with 8sp Chorus components shown below.

I ran out of time/energy/initiative and became a mixed 'occasional runner/occasional couch pototato' for more than a decade. More recently I recreated my initiative, discovered that at age 65 running was no longer part of my future, so I resurrected the Binachi, upgraded to Chorus 11sp (circa 2014), and am now 'a cyclist'. The before/after is below (after on the left).
