Challenge yourself and train your body for endurance by completing the distance of 1500km on any route before the end date. Work on your stamina and cardiovascular conditioning by building your aerobic fitness and endurance with long and short rides.
Endurance TIP:
Try to keep your cadence at the high end to improve your speed skills and prevent fatigue from setting in too soon. Aim for 2-3 times per week and two longer rides on the weekend. Prepare your pain cave with enough liquids and nutrition. The stunning landscapes and scenery revealed along the way make it well worth the effort!
Ride 1500km on any route in Time Trial, Race, or Just Ride mode without lowering the "reality level".
