This training plan is a generic plan aimed at the beginner rider, yet it can be done by almost any rider looking for some structure at improving their Aerobic Endurance. This is the single most important aspect for cycling and generally is the limiter of most riders. Being committed and stringent to the levels is a must, this will also allow you to become a more focussed rider. Train smart not always hard... Endurance rides at Level are exactly that, do not build additional fatigure into the legs, thereby struggling to complete the harder more focussed rides in the week.
