My group is pacing at a 17min mile and I have no problem with it. At first I was a bit disappointed in myself because I knew I could do better. But then look what happened, started too fast, pushed too hard and bam! Shin Splints. So I am really starting to learn what my body can take and how fast it can take it. And right now my body is telling me that I should stick with my pace group and not push it too fast. I'm already on pace to finish strong, I know I can get stronger, but I still have a full 9 weeks to get me there. I'm finally in no hurry. Took me 6 weeks to listen to my body, slow down, and be ok with it. But hey, at least I'm there.
So, I have no problem slowing down. Coaches say that when you slow down you are actually training your body to burn fat and strengthening those muscles. And strong muscles is what I need right now. Get my skinny legs going!
