Early morning workout

We are checking out of the hotel later this morning. I wanted to get my 10 mile run in early, and maybe play in the pool a little later this morning. I woke up at five-something, and finally get out of bed about 6am. My neck and back were stiff and sore. I am looking forward to sleeping in my own bed. I got dressed in my running stuff in the dark, and headed down. My room key wasn’t working to let me in to the fitness area. Finally a security guard came by and let me in. There was a guy already in there. I got on the treadmill and began my running. After a warm-up, I began alternating between 3 minutes at 6mph and 2 minutes at 4mph. The room was really hot today, and it felt like I was running in a sauna. I thought my back and neck would loosen up, but they didn’t. My neck was stiff and I had it was hard time even tilting my head back to drink water. I ended up only running 5 miles, and returned to our room. I took some Ibuprofen which I am hoping will make my neck and back feel better. I will run the other 5 miles on my treadmill at home. Hopefully the soreness goes away from my neck and back.
