History: w1d1 completed last week after 3 tries. criteria for completion was simply making it through all 8 jogging intervals without having to stop jogging during the run sections.
Today I took at stab at successfully passing w1d2. My criteria for passing this day is that
I finish all 8 intervals without feeling dizzy/pukey/jittery. I found last week (and again today) that by interval 7 I start feeling those things. I force myself to run through them, but I know it's not good/normal/healthy to be feeling those things during the cardio. I will keep repeating this day until I pass. I'd like to find out what is causing it- possible culprits include low blood pressure, low blood sugar, lack of oxygen (pushing my heart too hard/going about my max output), or heat exhaustion. It was cooler today- only in the 80s, so I don't think it was heat exhaustion. I'm going to take my pressure and sugar readings before and after my run on thurs to try to shed light on the problem. I did see that a lot of people have this problem though: http://cafty.wordpress.com/2008/09/25/dizzy-while-running/
Once I pass this day (hopefully soon), I will work on w1d3 and my criteria for success of that day is making it through all 8 runs without feeling out of breath at the end. The podcast dude tells me during the session each time that I should be feeling as though I am working hard but still able to hold a conversation while jogging without being out of breath. I am definitely not there yet and want to accomplish that before moving on to week 2.
Man, this is going to take forever. :(
Positive note: when I was running during intervals 1-5 I felt fantastic. Full of energy and I think I naturally found a faster pace that felt great. I was so excited that it was coming so easily that I actually laughed out loud and cheered for myself.
