I wish you luck, just keep in mind tho a lot of the people you are going up against, have the skill and the endurance. There is something to a lot of time on the bike. There muscle are very different and the body works different, from someone that is just in great general shape.I am not saying you not going to do good.
But just keep in mind not to cause problems for anyone because of your bike handling skills are not at the same level has the others you are racing against.That is a good way to make a lot of people mad at you, and you can get people hurt also.
