“Centuries,” those 100-mile bike rides that experienced cyclists like to mention in casual conversation, are actually not that casual. How not casual are they? LiveStrong offers a five-step guide to cyclists with their eyes on a “cent.” First, we learn that you should be able to ride 35 miles every other day for several months before attempting a century. Got that? Good. Next, increase your daily and weekly mileage no more than 5 percent per week. Step 2: Add a speed session or challenge yourself on a hilly course every two weeks. Step 3: Do “recovery rides,” for which you slow your pace and ride on a flat, easy course one week a month. Step 4: Get plenty of rest throughout your training and eat clean foods. Finally: Train at your pace, and most importantly, enjoy the ride. Read more at LiveStrong. Wait, there’s more on how to train for a century from The Athletic-Minded Traveler.
