Just did my 3rd of the year and 6th overall, this morning.
One of my best and worst ones ever.
I dropped my chain at the beginning of BOTH sprints! So I did the only sensible thing… I rewound the video to try again. And I dropped my chain AGAIN! So… I rewound the video for a fourth try. This one started out good, but I dropped my chain a FOURTH time, but this time at the END of the sprint - which was not my best sprint since it was, of course, my fourth try.
The mixture of dropped chains and being tired really messed with my head. I just didn’t want to suffer any more this morning. But, I did it, anyway. I did SOOOO many mental gymnastics to get myself to the end. I wanted to quit SOOO badly during both the 5 and 20 minutes sections. BUT I DIDN’T. And I managed to match my highest MAP score every from the HM I did last week. And I nearly matched my FTP from HM, as well. Only 4w below. But I’m going to chalk that up to doing 4 sprints. That, and my son distracting me by walking in at 6am with 11 minutes left in the 20 min effort and me yelling at him that it was too early and to go back to bed. Father of the year award there, folks. 
However, I had NOTHING left at the end. I was worried about dropping my chain during the 1 min effort, so I try to build into it rather than start out sprinting. That didn’t help. That was the longest minute ever in my life. Longer than in any of the other FF’s I’ve ever done. I got out every last drop of power I had, but still my AC dropped 14w. Despite being in the best shape I’ve ever been in the bike, my AC is now 40w lower than my best ever AC. I’m going to chalk that up to the 4 sprints and dropped chain, too. After the 1 minute effort all I could muster for the final cool down was 30w at 35rpm. Just barely keeping the pedals turning.
Yes, I have suffered today.
