So I was at the Track yesterday to gauge myself on how the 6 week recovery treated my Cardio Vascular endurace. I was not very pleased with what I found out: I had trouble running a single 800meter sprint, let alone the 10 repeats I was planning to do with only a minute's rest between each sprint. I was throwing up after the third, but I continued on for 8 repetitions and finished with a 3 mile cool down.
Needless to say, I need to do more speed work to get back what I used to have (and beyond that), so I will be at the track my 2 days off from work at 6 am sprinting my heart out :-)
I'll keep you up to date on how it's working out for me
