Today's training session was a Fartlek. While it may sound like a body malfunction, Fartlek actually means "Speed Play". I haven't done a lot of these because I don't really enjoy them. I prefer a constant speedy (tempo) run than the burst of speed that Fartlek calls for. I'm not even sure if I do them properly, looking at my pace chart I'm kinda satisfied that I did some burst of speed. I may try to sustain the bursts for longer periods next time I get around to doing another speed play session. I shortened the duration a bit since I didn't have enough time to do the entire distance prescribed by my training plan.
I think that the out of breath and close to collapsing feeling is normal for this type of workout. If there were two things I would like to see on my next chart is a more constant pace for the easy sections and a longer burst duration. Other than that I'm fairly happy with ~49 minutes for 10 kms. One thing I never know when I do these types of speed workout is how the total time is supposed to compare to a tempo run.
How weird street fair in the mix.
