I am setting a goal of riding a full Century on June 7th. It is our annual charity bike event to benefit cancer patients families. I trained for the metric century last year and it was rained so I decided not to ride. Right now it is too cold and dark for me to ride after work and I have other obligations on most weekends. I have joined a new gym here that will offer my normal water aerobics classes I usually do in the winter/spring and they will offer a spin class. My brother's riding group can ride year round (Houston) and he is already faster than I am. He has offered to ride with me (he did his first century this summer). One of the ladies I ride with suggested that I concentrate on building leg muscle this winter. Do you ladies have any suggestions for gym work that would help me this winter prepare for the century? Do I need a cycling specific workout? I also have another 40lbs to lose before my doctor will be happy. Thanks in advance for the suggestions.
