I have just completed my third 10 mile TT. I maintain a fairly high cadence throughout the TT and in training (90 to 100). Apart from on loger training rides (50 miles +) I rarely feel any discomfort or burning in my legs. Even after a 10 mile TT at av HR of 175 (92% of max) I cannot feel any buring in my legs. However, where I do suffer is in my heart and lungs. On uphill stretches where my HR may increase to 180 (95% MHR) I am gasping for breath and my chest tightens.
I am following a simple training plan and one of my turbo interval sessions is for strength (6 x 4 mins at 90% MHR/cadence 70rpm with three mins easy pedalling between work). My legs ache at the end of these sessions but my breathing is regular. I have been trying this technique on the road and find that although my HR is 90%+ my breathing is much more relaxed than when I pedal at a higher cadence. I am now considering dropping my TT cadence to 80 RPM. Anyone have any thoughts on this.
