I took second at USATF Nationals Cross-Country when I was ten. I was 6th at nationals in the 3000 in 2004.
Personal:
I did lots of competitive running growing up. I'm now 23 and have fibromyalgia and CFS. I just finished nursing school and am going back for my MSN in a few months, but I want to get back in shape and be able to run again.
I walked for 20 minutes and jogged for 20 minutes. I went 2.6 miles, I wanted to do an hour but my shins were hurting so bad by the end I was almost limping, so I did 20 minutes of pool running to finish my workout.
Today I ran 1.5 miles in 17:35, and then I walked till I was at 20 minutes. I then lifted a few weights on my arms. My shins hurt and towards the end it was almost too much. I don't think it's from overuse because I don't think I'm doing enough for that. I just got new shoes so that shouldn't be the problem either. I think they are just weak and as I build the muscles back up the pain will subside. At least I hope that's the case.
