I tried to run today, I think I did OK on speed but distance is of big concern.
After my first lap I was tired, my head was not in it, so I slowed to a walk. Ask I walked I noticed I was spitting blood.
I think it was not coming from my chest though, I think it was my sinus.
Will continue to monitor the situation, tomorrow hope to get up early for a run even though it is 1 lap.
