Questioning my Decision

After a much needed break for my muscles, I finally went for a run yesterday. I felt really good. I was thinking, "Okay, we are back and ready to go." Tonight I had my first official training session for the race. It was quite a humbling experience. I was really worried about it. I was just hoping that I could hang with everyone. I did fine with the running, however not so good with the rest. We did push ups - did ok. We did pull ups - I had to do the assisted machine pull ups. We did tricep work - no problem. We did hanging chin ups - huge problem!! I could hang for 15 seconds, but I could NOT pull myself up and hang. It was awful. I felt defeated. I have been lifting for a year now and I thought that I was much stronger than that. I am already sore. I can't imagine how sore I will be tomorrow and Thursday. I have a lot of work to do and much ibuprofen to take! I am now wondering if signing up for this race was a good idea.
