I am hoping to start racing some cat 5 races (RR, TT, and Crits) in the spring. I've never done any bike racing but have done about a dozen triathlons. Right now I am only building base milege and will start with some tempo rides and repeats after the 1st of the year. My speed seems to be getting better without too much hard riding right now, and yesterday I rode 65 miles @19.5 mph solo. I was riding steady and got my HR up on some climbs, but wasn't pushing all that hard. My question is, if I keep riding and start some serios riding soon, will I be OK for some Cat 5 racing in the spring? I really don't want to get dropped quickly and struggle through races, I would rather wait until I am in good enough shape to compete before I start. Also, does anyone have any advice to keep me from looking like a fool as I attempt this?
