Race 1- I was the sucker closing things down
Race 2- Crashed, misjudged a descent when on the front
Race 3- Got in the early break which got reeled in, made a move on the final climb and took 3rd to move up to 3rd cat
Took me another 5/6 races to get my 2nd
The point I was going to make is that before this I spent a year commuting 60km everyday, and doing a chaingang twice a week. Racing will bring your game up, but you need to have a pretty good game beforehand.
I'm not sure i'd encourage anyone to get involved with 4th Cat only races unless you are fairly confident you can move up quickly. Crashes are inevitable at any level, but just seem extremely prevalent at 4th.
