TL;DR - TrainerRoad workout running at 5/8 of real time.
I had Phoenix on the schedule today, and dutifully got after it this evening. As always I was running TR on my PC, connected to my P1s with PowerMatch enabled with my Kickr Snap. I also record rides on my Garmin to have the data is many different places (more data is better right?)
I knew Phoenix is just under 100 TSS for a 90’ workout, and looked at my watch ~30’ in and saw that I was already at 50 TSS for the workout, and thought that was odd. I kept going and noticed that the math kept not working out for a steady state workout. I checked the Garmin and sure enough it was at 56’ minutes when TR had me just past 30’. I was confused. I checked my phone and looked at the time I sent a text to a friend before I started pedaling, and sure enough it was 56’ ago.
At this point I thought I was in a black hole. I was confused. Both clocks were ticking away, but they were diverging. I broke out the stopwatch and realized for every 15 seconds that TR ticked off, 24 seconds passed in real life. I was even more confused. I still wasn’t convinced, so checked how long the movie I started had been playing, and that was 56’ too. Now I was convinced.
Any one else ever had this happen?
On a positive note it explains why the first “30 minutes” of the workout felt like it took so long, on a negative side this was also the start of dialing in my nutrition timing, and it certainly didn’t help that!
Links below show what I mean. TR ride shows 56’ total, while Garmin shows the whole 90’. If I was feeling fancy I would overlay them and make a pretty picture, but dinner sounds better.
