Adaptation or Wimpishness?

Yesterday was a wipe out. The combination of missing a morning workout followed by the traditional "Pizza Night" led me to crumble.
So best intentions began Saturday. Plan was for a two hour outdoor ride and a one hour swim. I made all the arrangements including correct gear.
Flash forward to 8 am---Temperature around 15 degrees and I cave.
So I did a 90 minute indoor Revmaster workout and now on to a one hour swim.

Adaptable or Wimp?
