After feeling quite pleased with myself for nailing run one of week 7 on Sunday, tonight's run was an epic fail.
I had to stop after ten minutes, I walked for a couple of minutes and then managed to do another ten minutes of running and the same happened had to stop at around the ten minute mark.
I did manage a third ten minute stint but I'm gutted that I wasn't able to run for a full twenty five mins.
What's happened? Anyone else had a similar experience?
