BMImpossible

Off target
Today's run (street): 3.5 miles

It's always nice to have a three day weekend, because it gives me an extra day to run during the week. If I'm lucky, the weather will cooperate. Unlike yesterday when the rain chased me indoors, today looked sunny and clear. Except for the near freezing temperature, it looked like ideal conditions for a run.

I dressed for cold but didn't put on too many layers this time. I stepped outside and confirmed that my gear matched the weather. I noticed that the driveway, that was covered by a shadow, had a thin coating of ice. When I reached the sunnier road I was happy to find it ice-free. That happiness was short-lived. By the time I reached the half mile point, I was dealing with patches of ice where the sun didn't reach the road.

It wasn't bad enough to stop, but I needed to be careful. I put aside any thoughts of performance and focused on landing on my mid-foot to maximize my stability. I didn't have any close calls like yesterday, but it didn't make for a very pleasant experience. For a fairly short run, it was exhausting.

I've continued to watch my portion sizes and have already lost a few pounds (I believe this is the primary reason women resent men). Based on the advice I recently got from a nutritionist, I did 12 push ups after finishing my run. I considered doing 15, but didn't want to invite upper arm soreness on top of of my diminishing (but still present) sciatica. Fellow running blogger Renee recommended the Matt Fitzgerald site to calculate my ideal racing weight and BMI (see graphic at top). Will I get down to 14.8% body fat? That would be a no.

  1. I went to that site and they told me my ideal racing weight was 108 from very little information (age, sex, weight). What if I was 5'10"?

    1. Yes. That's my point. I would need to go without food for a month to reach 14.8 BMI.

    2. Not BMI, which is body mass index, but body fat percentage.

    3. I thought they were the same thing so I found a body fat calculator online. Still no.

  2. Thanks for the link. Surprisingly encouraging. I came in at 185 lbs, and 12.9 %. 185 has been my goal weight, and it's doable I think.

    1. Mine was 155 lbs. I didn't get that low when I had pneumonia. I'll stay with my current target.

    2. http://www.cdc.gov/healthyweight/assessing/bmi/

      BMI calculator, for what its worth. I'd still be considered overweight by BMI at my ideal racing weight.

  3. Thanks for the mention :) Matt Fitzgerald’s book "racing weight" is a really great read on running nutrition and weight loss principles whilst training but maintaining enough fuel for training load… my "ideal racing weight" is 14.8% bf, which I won’t be getting too either ;) but is what I would gun for if I was an elite… lucky for me I am a recreational runner ha ha.

    1. I'll look for the book in the library. I'm not going anywhere near 14.8% bf but I'm hoping that getting closer to my weight target (not Matt's) will yield some increased speed.

  4. Estimated Ideal Racing Weight: 101
    Estimated Target Body Fat Percentage: 16.2

    I've gotten down to 102 and 19% and thought I was too thin. I ran the 10 miler at 105 and 21% (according to my aria scale.) Weirdly, I've always thought that I ran best at 105. If I could stay at that weight and increase lean mass at the same time I'd be thrilled.

    1. You and SIOR weigh nothing. I'm surprised you don't get carried away in a strong breeze. I'd also like to get to target and increase lean mass. I'm afraid that if I lose the weight I'll lose some muscle mass as well.
