A “Century” is a single-day 100-mile bicycle ride. For beginning recreational cyclists, a century is a rite of passage. If you can ride a hundred miles in one day, you’re part of a club.
If you’re thinking about riding your first century this fall, here are four things you need to keep in mind if you want to have a good ride: (1) the suffer point, (2) effort, (3) hydration and nutrition, and (4) comfort.
The Suffer Point. At some point during your first century, you’re going to suffer. Which is to say, you’ll be asking yourself, “why did I do this?” That point is your suffer point. If you hit your suffer point anywhere after 80 miles, you’ll be okay. You’ll struggle, but you’ll finish. On the other hand, if you hit your suffer point too early, you’ll be in trouble. Hit your suffer point very early, and you may not finish, or you may risk injury if you try to.
A good training program will push your suffer point backward. Experienced, well-conditioned cyclists have suffer points beyond 100 miles, so completing a century, even a self-supported one, is not a huge problem for them. Most beginners do well to push their suffer point to 75 to 85 miles for their first century. But no matter what your experience level, if you show up undertrained, you’ll hit your suffer point too early and risk disaster.
To do: The centerpiece of your training program should be moderate increases in your weekend ride, say, 10% to 20% each week. The best program is one you design yourself, perhaps with the help of an experienced cyclist acting as your mentor. This allows you to build in flexibility and target the specific areas where you need to improve. Follow this link for some good advice on developing your own training program.
Of course, your suffer point is not a static parameter. Your training program will establish it (in theory), but your decisions the day of the century can move it in the wrong direction. This is what you want to avoid.
Effort. The last thing you should worry about for your first century is how fast your bicycle is moving. The speed of your bicycle is a function of several variables, most of which are beyond your control, such as the wind and the road gradient. Instead of focusing on speed, focus on how hard you’re working, measured by breathing, heart rate, cadence, and gear selection.
Your effort needs to be gauged for the time you’ll be on the bike, about six hours (more or less). So you need to develop a pace that you can sustain for that length of time. If you go out too hard at the beginning, because your adrenaline is pumping, or because you’ve hooked up with a fast group, you’re going to blow up somewhere down the road. Essentially, you’re drawing your suffer point in. If your training has pushed your suffer point to 85 miles, but you fly out of the start with an effort that outruns your training pace, your suffer point will move to 80, then 70, then 60 miles, until eventually the actual mileage and the suffer point meet. Whenever this happens, you’re toast. And the rest of the day will be miserable.
To do: Ride at a comfortable Zone 2 pace, a pace you can maintain for several hours. Choose relatively low gear ratios and a high cadence to shift pressure from your muscles to your cardiovascular system. Resist the temptation to ride hard. Avoid groups that out run your training pace, and save your energy through the first two thirds of the day. If you want to go fast, save something for the last twenty miles.
Hydration & Nutrition. You need to take in at least one bottle of water per hour, and 70 to 80 grams of carbohydrates per hour. If you fail to get enough water and food, you’ll draw in your suffer point, rapidly, even if you’re riding at the correct effort level. If you bonk because of dehydration or hunger, you may wind up on the side of the road making a desperate cell-phone call for help.
What specifically should you eat and drink? It’s up to you. Use your training rides to find what works. Plain water combined with gels, Gatordate combined with Powerbars, Perpetuem combined with plain water and energy bars, or something else. Talk to other cyclists to get ideas and experiment with different combinations to find the right combination that allows you to maintain your effort for several hours.
To do: Don’t change your hydration and nutrition strategy the day of the Century! If the organizers aren’t providing your choice of beverage and food, work out a way to carry what you’ll need. For example, if your choice of beverage isn’t available at the rest stops, consider carrying small containers of powder and mixing it yourself at each stop. (The organizers will certainly make plain water available at each stop.)
Comfort. The issue here is joint and muscle fatigue that develops because of sitting on the bicycle for several hours. You’ll win 90% of this battle by choosing a road bike instead of a comfort bike, hybrid bike, or mountain bike. (Not to mention the fact that those types of bicycles, heavier and less aerodynamic, require more energy per pedal stroke than a road bike for a given set of road conditions.) Staying comfortable is a simple matter of periodically adjusting your hand position on the bars, and standing up to pedel every 15 minutes or so, or on each hill.
To do: Change hand positions often. Stand up to pedal on small hills, or every 15 minutes if you’re on flat ground. Stretch your neck from time and time, and take time to stretch at the rest stops.
