I want to run a variety of races in 2011 - a few half marathons, 1 full, and some other random distances just for fun. One thing I struggled with this summer/early fall is training for a half marathon and a 5k at the same time. It was hard to balance speed work with quality distance runs for me, plus I was still trying to build up my iron count. After looking at various race calendars, the earliest half I could do would be in March, with gives me plenty of time to train. Although, I must admit, I'm already in half shape, and pretty good half shape. On Friday I ran 10 miles at a 7:38 pace. However, being in half shape is far different than being in 5k shape.
I know that speed work is an ideal part of most training plans for half and full marathons, but I'm just not a real fan of it, and never have been. I am going to do a 5k for St. Patrick's Day on March 12, so I decided this weekend that I better start to train for it, as I want to PR (21 here I come!). Today I did 5 miles at a 7:25 average, but my miles got progressively faster as I went along. I think today's run was a nice building block for me for the next couple months of preparation for my 5k and possibly half/halves in the spring.
One thing that I have noticed much more with quick runs as opposed to slower run (8:00 miles) is the impact on my blood sugar. Although I might end my workout with a blood sugar of 70, which although is not ideal, is fine for me, I spike big time post-workout. I used to completely disconnect from my pump when I ran, but now I leave it on the whole time and don't bother to reduce the basal rate. I eat some Shot Bloks as I workout because I need the energy anyway. It just seems to work better, although afterward I'm still going higher than I would like. I realize it is not possible to always be between 80-100, especially after a meal, but I don't like to see my blood sugars going higher an hour after I work out for no apparent reason on some days, but stays fine on other days. It is a mystery on life to me.
Does this happen to you? Or, do you know the cause?
