So I had my first race today, the Charm City Cross in Baltimore. It was awesome, I had a great time and a good ride for my first effort. I entered a few weeks ago but even then the Cat 4 was already filled so I entered the 35+ 3/4 masters. The field was nearly 100 deep and my number was 75 so as you can imagine myself and a gaggle of others started way in the back. Long story short is I finished 79th but I had the circle of death around my race number as did about 25 others. I figured this means I got lapped, which is no big deal for my cherry popping, but I am still a bit confused as to how the whole placing and finishing equation works out. After extensive searching and even scouring the "Cyclocross" book, I still can't find a basic explanation. Does anyone have a simple way of explaining it?
