In terms of training, it is best to practice skills like cornering, braking, riding in groups and drafting, and eating and drinking while still on the bicycle. This helps you if you are training for a time-based event where you need to perform your fastest. Next in training would be working on your endurance to sustain your energy levels for a longer period.
When it comes to endurance training, if this is your first time riding a 100, start training a few months ahead with a combination of other work outs like jogging, walking and weight training and incorporate your cycling into your routine. Start out by covering a shorter distance and building up to covering larger distances each week of training.
RIGHT BIKE FIT
To maximize your performance, it is essential to make sure that your bicycle is the right size and fit. Faulty sizes, and fit, will lead to unnecessary pains and efforts with reduced performance.
