Today my training plan called for baird +6, which is 60 minutes of V02 intervals, followed by 30 minutes of aerobic riding. With the weather improving, I am now able to ride my bike to work. I had a bit of time crunch, so I did the intervals, and then instead of riding 30 minutes aerobic on the trainer, I replaced that with my commute, which is almost exactly 30 minutes by bike. However, in between the intervals, there was about 30 minutes off the bike so I could get ready for work. I didn’t take in any calories in this window.
My question is, am I losing the benefit of the aerobic riding by taking this break in between, or am I just being efficient ?
