Anyway, I ran 3.1 miles again, so now I know I can do this and the first time was not a fluke =P Here are my split times from today compared to Monday.
As you can see, even though it did not feel like it as I was running, I did it faster too: almost 1 1/2 minutes faster. If I can just shave off one more minute, I can run a sub-40 5k! I think I can do that :) Though I need to remember that it will be a lot hotter on Saturday, so I shouldn't be disappointed if I it takes me longer.
When I started walking, I felt a slight twinge on my right knee; it was nothing major but I was conscious of it. I think I was overcompensating for this the whole time so I would not get hurt and my stride suffered (it did not really hurt when I was running but I think I was being overly cautious so it wouldn't). This knee (on top and just below the knee actually) tends to act up from time to time, so I think is overuse. As much as I want to, I don't think I'm going to run again until Saturday because I do not want to risk injury and not be able to run Sat. I would be so mad if that happened. I think I will stick to my biking and just go for an easy walk on Thursday. Maybe do a bit of strength training on the knee. What are good exercises for that? Squats and lunges, right?
