Help wanted.....

Does anyone else experience terrible nerves before going for a run, not only before races but when you're trying out a new distance or just getting out there? I always get really nervous when I'm waiting to run in a small distance race of 5km but sometimes it's before I do my usual runs during the week. The nerves always give me an upset stomach so it makes me feel terrible before I start, any ideas as to how I can reduce this happening. It's not about confidence as I know I can run and I enjoy it so why does it happen?

Anyway this morning I went out for a little 3 miler down to the beach, despite the fact it had been raining all night it was still warm so had to take my waterproof off half way. Not an easy run, I didn't feel very spritely but I'm glad I went. Off to do some sit ups and a press up!

Edit: 50 sit ups and 5 pathetic press ups that probably wouldn't actually pass as a press up.
