I completed my 3rd ZA SF Kickr workout, VO2 Intermittent, Wednesday evening … OOMPH this one was another doozy!
The workout consisted of a WU, 5 min recovery, and then 5 min at just under FTP, immediately into 10x 15sec seated sprints/25sec rest, followed immediately by another 5 min at just under FTP. This was then repeated 2 more times, with 5 minutes of recovery in between.
I rolled into that first interval feeling great, but by the time I hit the seated sprints, my legs were already feeling quite heavy! I gave the sprints everything I had (OUCH!), and then settled back in for the 5 min post-sprint Threshold Interval… hung on for dear life & completed it successfully, but Dear God it nearly killed me! 
🤣
🤣It’s workouts like these that make me so very thankful that my body recovers quickly during rest intervals… I was feeling pretty good again by the time the 2nd & 3rd Interval started, but by the end of each sprint section, I was 1/2 second away from passing out & falling off my bike again!
As I’ve said before, sprinting is a weakness of mine that I’m working hard to improve upon… so a workout like this was about as far from my “wheelhouse “ as it gets, & despite my BEST efforts, I didn’t hit the RXd sprint # a single time, BUT I did a really good job with the pre AND post sprint Threshold Intervals (thank you engine!

I have to admit, I’m really looking forward to this one (15 min Test)
