Well the good news is that I have discovered why I am struggling so much. The bad news is that it could take another 6 to 8 weeks before it gets better!. I have to be the most stupid person in the entire history of people, why oh why after 53 years of excuses did I choose this time in my life to donate blood?
Searching for a reason for my complete failure this week I googled 'giving blood whilst marathon training' or something similar. There were many answers, all said basically, not a good idea but one explained why, it read:
donating red blood cells, either through a whole blood donation or through an automated process, will have a negative impact on any endurance activity. The reason is red blood cells carry oxygen in your blood. Without those, your muscles will tire extremely quickly. It takes about 8 weeks for red blood cells to regenerate. Unfortunately, I learned this the hard way!
. . . bit like me then!
What an idiot, why didn't I investigate first - because I never do. At least though I Know why and I won't be quite so hard on myself over the next few weeks.
Running for health, happiness and a good laugh whatever your age, size or fitness level
