The return of the blood faries

I did 10miles this morning. Felt good. Legs where a bit stiff. Then I did 5 miles this afternoon. However, when I started out I started to cough up blood. It's more annoying then worrying. I hope I'm ok for my fast 10miles 2moro. I also have huge blisters which decided to bleed today. So basically my body is slowly turning into a sieve. I'm running out of time on the Internet so I shall keep this short and sweet.
