Tomorrow, I'll do a long run of 5 miles. I haven't run that distance in four months, so I'll be curious to see how it goes. I know that my low-calories (and low-carbs) have likely made me weaker on my runs/rides. I will have to play with a good target of daily calories for my current activity and weight loss goals. My guess is that it will be around 1,800 - 1,900. This week, it has been less per day.
UPDATE: My run this morning did not go well at all. I intended to do 5 miles, but only got 4.4 miles done and I walked most of the second half. What happened? I am guessing, but I think I was too hot (about 90 degrees), I had too few calories in me the last few days, and maybe I went a bit too hard on my first week back at running after a few months away. I'll rest today and tomorrow and do a 2.5 mile run on Tuesday.
Here is my report from last year's 5K race.
What is your next big race or event?
