This 12-week cycling plan is for the individual who has already been riding 2-3 hours per week. The participant should have been exercising regularly for at least 3 months. The focus of the plan is to provide a sensible and systematic approach to cycling regularly to achieve the initial goal of finishing a 100K ride (62 miles) and/or setting the stage for more extensive cycling (i.e., longer or faster races) in the future.
