Did my first ten just over a week ago, so know how you're feeling.
Broke the strap on my helmet before the warm up, and then the chain came off during the warm up, so I approached the start line with oil all over my face and hands and a broken pointy helmet.
Felt so nervous that I forgot to peddle when the starter released me and nearly fell off!
After about 3 miles into a head-wind, I felt like giving up and throwing the bike over the nearest hedge, so hard was I finding it. But you carry on, and, when you eventually trundle across the line, lungs burning, chest pounding and having aged by at least two years, you feel.......fantastic!!
Good luck. It really is worth the misery.
