im 5''11 and weigh 11 stone (150 pounds) i have been cycling since last year, and recently joined a club, to start racing against people my own age, instead of just training with my 40 year old neighbours, who during the winter months forget about cycling, where as i train on myself. as of now, i am averaging 18 mph over 30 miles +. and my cadence is averaging around 100 over any distance. but there are a few things i would like to find out about, should my cadence be so high, i do not feel comfortable at a cadence of 90 or below, especially climbing, and i cant increase my cadance as i am in lowest gear for most of the steep hills were i live in northern ireland. so shud i start doing squats with weights to build thigh muscles or get a lower gearing, or shud i just grind through the hills at a cadence of 80 or 90 until my legs do get stronger. another topic is heart rate, my heart rate is averaging around 180 - 185 for training, and the highest i haveseen my heart rate at is 205, all out effort, is this correct for my heigh, age etc. and finaly, my weight, i have seen on other threads, someone said we are all to fat for this sport, but should i be considering losing weight,as i have got a bit of a gut that i wudnt mind replacing with a six pack btw i have finished growing. i would like to thank anyone who replies with a viable response, on one or all of the topics stated.
