This workout is one that I read about from a well-respected online triathlon coach who uses power meters in his bike workouts. It is supposed to be a 1 hour workout, but I cut it short to 45 minutes, because I got up a little late, and I need to be at work early today. The workout involves an easy warm up followed by 5 x Work Interval, where the work interval involves riding at about funtional threshold power (FTP) + 5% until your heart rate reaches lactate threshold (LTHR) + 3-5 bpm and then recover. For me, FTP = 275 watts and LTHR = 168 bpm.
The graph makes it pretty clear that these intervals are not uniform. It took several minutes for my HR to get to LTHR+3 in the first interval. However, by the last one, it was only a minute or two. Following the intervals, I finished off the session with some spin ups shake out my legs a bit. Those PPIs really start to hurt! I'll be very busy at work today, but hopefully, I can get in a L4 run. I haven't run since Saturday, and I really need to keep these legs moving!
Dude, you are going to thrash me on the bike. Looks like I will need to run you down. You'll be my rabbit!
