Spinervals 6.0

Today is supposed to be my day off, but I was frankly too tired yesterday to consider putting in a reasonable effort on the bike or swim.  So, I biked today.  Spinervals 6.0 Zoot Challenge.  Quite a bit of high-cadence work and sprint sets.  This workout, I feel, was a good effort.  I wonder if I need to change the location of my bike on the trainer.  The wheel keeps squeaking no matter how much air/pressure I have on it.  I also need to adjust my rear derailleur.
