This is my first post in this forum and I know nothing about training. I am 6'4 225 pounds at about 15-18% body fat. I ride about 3-5 days a week with no direction on both road and mountian. I eat fairly well but could lose some weight. I was down to 205 last year but looked very thin, almost to the point where my head looked too big. I have always been an athlete. I played football in college and surf a lot now. I would like to get some direction because I finally have a goal and that is to participate in the Wolfpack ride in LA which is a 35-40 mile ride through the city at a very fast pace. (I would point you to the website but its slllllloooooooow) I know that I would get dropped like a rock if I tried it now. I can ride 2 hours about 4 times a week and live at the base of a 3/4 mile straight uphill. I have three bikes: a SS mountian bike which I use once a week on the trails, a geared cross bike which I ride as a road bike, and a fixed gear road bike which is my favorite. A good loop for me in my area is about 15 miles of varied terrian, on bike baths and streets I can make that a 20 mile loop pretty easily. Any help would be very much appreciated.
