1. What is the difference in distance between a metric and imperial century?
A metric century is 100 kilometers (62.13 miles), while an imperial century is 100 miles (160.93 kilometers). An imperial century is roughly 61% longer and typically requires 2 to 3 additional hours in the saddle.
2. How long does it take to complete?
Moving times depend on terrain, elevation gain, and drafting:
Metric Century (62 mi): 3.5 to 5 hours (averaging 12–18 mph).
Imperial Century (100 mi): 5.5 to 7.5 hours (averaging 13–18 mph).
Total elapsed time usually includes an extra 45–90 minutes across aid stations and mechanical breaks.
3. How far in advance do I need to train, and what should my longest ride be?
Most training plans span 8 to 12 weeks. You do not need to ride the full distance in training:
For a metric century, completing a long ride of 45–50 miles 2 weeks prior is sufficient.
For an imperial century, peaking with a 70–80 mile ride provides enough physiological conditioning and confidence without excessive fatigue.
4. How much should I eat and drink during the ride?
Under-fueling is the primary cause of bonking.
Carbohydrates: Target 30–60 grams/hour for moderate efforts, or 60–90 grams/hour for harder paces (using a mix of chews, gels, bars, and liquid carbs).
Hydration: Drink 16–24 oz (500–750 ml) per hour, alternating between plain water and an electrolyte solution. Start fueling within the first 30–45 minutes rather than waiting until you feel hungry or thirsty.
5. How should I pace myself to avoid blowing up early?
The golden rule is staying well below your threshold. Keep efforts in Zone 2 (endurance) for 80%+ of the ride. Spin a smooth cadence (85–95 RPM) and strictly cap your power or heart rate on early climbs; burning matches in the first 25 miles almost always leads to severe late-ride cramping or deceleration.
6. What gear, spares, and tools are mandatory to carry?
Self-sufficiency is critical, even on organized events:
Flat kit: 2 tubes (or tubeless plug kit), tire levers, and a mini-pump or 2–3 CO2 cartridges.
Multi-tool with a chain breaker and quick-link.
Pre-loaded offline route on your GPS computer or phone, emergency cash/ID, and basic first-aid/chamois cream.
7. How do I prevent saddle sores, neck/shoulder pain, and hand numbness?
Discomfort over 4–7 hours usually stems from bike fit or contact-point issues:
Get a professional bike fit before logging peak training volume.
Wear high-quality bib shorts without underwear, and apply chamois cream generously.
Change hand positions frequently between hoods, drops, and tops, and regularly drop your shoulders to release tension.
8. What should I eat before the ride and the night before?
Night before: Eat a high-carb, moderate-protein, low-fiber, and low-fat dinner (e.g., rice bowls, pasta, sweet potatoes) to top off glycogen stores without causing GI distress.
Morning of: Eat 2–3 hours before rolling out (oatmeal with banana and maple syrup, bagels with jam, or toast with eggs).
9. Organized event vs. solo: which is better for a first attempt?
Organized events offer substantial advantages for beginners: marked courses, mechanical support, fully stocked rest stops every 15–25 miles, and groups to draft behind (saving 20–30% energy). A solo ride offers flexible scheduling, but requires carrying more gear and planning water/refueling stops at convenience stores along the route.
10. When should I taper before the ride?
Begin reducing volume 7 to 10 days out. Cut total mileage by 40–50% while maintaining a few short, race-pace efforts to keep your legs responsive. The week of the event should prioritize sleep, light spinning, and carb-loading rather than trying to build last-minute fitness.
