I'm 34 years old, been riding for 10 years on and off and I'm determined to start racing this year. I have a race-training ride this saturday with a group and frankly I'm a bit intimidated by what I might experience out there. We're going to do some race simulation and some sprint work. I'm definitely not new to cycling. I have spent a lot of time out on the road and some time riding in groups, but never at high speed and my training this year is still in the foundational period until the beginning of Jan. I'm prepared to accept whatever fate hands me on Saturday and I'll keep training, but do the more experienced folks have any tips to help me make it through?
