hello, i have a dh mountain bike race coming up in about 3 weeks. i have a single pivot bike with fox dhx in the rear. i have 04 boxxer shocks too. they have two courses, i have rode both many times. they are both very technical and usualy wet. i have 2 years dh mtb experience, and i can make it down the mountain in about 4:58secconds (my friend timed me) the pro's make it down in 4:10. am i ready to race? im only 13, 65 inches, weigh 114, and have good stamina. just wanted to know how i would possibly do. also, what tires should i get? because the course is many slanted rock faces that are more than likely going to be wet and slippery. the rest is a standard rock garden, random steep declines, jagged rocks, mud, turns, the normal. any suggestions on what to do? anything that will help me during the race will be apreciated
