Hi all - I am re-doing a programme to get me back to 10K (the Zenlabs C210K one). I have just finished week 9. I found the last 2 runs really hard - they were 4x10 min runs, with 1 min walking in between. I wimped out on the middle two, so they were more run/walk.
I gave blood about 10 days ago and have been feeling tired since then. Has anyone else had this kind of issue after blood donation?
