- You need two things for a century: enough endurance to ride 5–7 hours, and enough pacing/fueling discipline to not blow up. The training builds the first; the strategy delivers the second
- 12-week plan: 8 weeks base (building long ride from 2 to 5 hours), 3 weeks build (adding tempo and a few threshold efforts), 1 week taper (rest before the event)
- The century is won in the first 50 miles: ride at Zone 2 endurance pace — conversational, not pushing. Most first-time century riders go too hard in the first half and fade badly after 60 miles
- Fuel from mile 1: 60 g carbs per hour, one bottle of carb drink per hour, a gel or food every 45 minutes. Bonking at mile 70 is a fueling failure, not a fitness failure

What it takes
A century (100 miles / 160 km) is a test of endurance, pacing, and fueling — not of speed or power. You don't need to be fast; you need to be able to sustain a steady, moderate effort for 5–7 hours, eat and drink enough to not bonk, and pace yourself so you arrive at mile 80 with enough left to finish.
The fitness prerequisite: before starting the 12-week plan, you should be able to ride 2–3 hours comfortably (40–50 miles). If you can't, spend 4–6 weeks building base endurance first — consistent 2-hour rides, 3–4 times per week — before starting the century-specific build.

The 12-week plan
A simplified 12-week century training plan. The key session is the weekly long ride — it builds the endurance the century demands.
| Phase | Weeks | Weekly volume | Long ride | Key sessions |
|---|---|---|---|---|
| Base | 1–4 | 6–8 hours | Build from 2h to 3.5h | Long Z2 ride, 2 midweek endurance rides |
| Build | 5–8 | 8–10 hours | Build from 3.5h to 5h | Long Z2 ride, 1 tempo session, 1 endurance |
| Peak | 9–11 | 9–11 hours | Two 5h+ rides (weeks 9–10), one 4h (week 11) | Long Z2 + some Z3 tempo in the final hour |
| Taper | 12 | 4–5 hours | No ride over 2h | Rest, 1 easy ride with a few openers, eat well |

Event-day pacing
The century is won in the first 50 miles. Most first-timers start too hard — the group is excited, the legs are fresh, and the pace feels easy. It's not. Every watt above Zone 2 in the first half is borrowed from the second half, with interest. Ride at a pace where you can hold a full conversation for the first 3 hours. If you can't talk, you're going too hard.
If you have a power meter, target Zone 2 (69–83% of max HR, or 56–75% of FTP) for the first 60 miles. After that, if you feel good, you can push into Zone 3. The most common century mistake is riding the first 30 miles at threshold and the last 30 miles at a survival pace.

Fueling the century
Eat from mile 1. Don't wait until you're hungry — by then it's too late (your gut can only absorb ~60 g carbs per hour, and the deficit accumulates). Target: 60 g carbs per hour (one bottle of carb drink + one gel or half a bar, per hour). Spread it: a sip of carb drink every 10 minutes, a gel every 45 minutes, real food (banana, rice cake) at rest stops.
Drink to thirst, but don't let yourself get behind. In warm weather, that's a bottle (500 ml) per hour; in cool weather, less. Add electrolytes (sodium) to one bottle to prevent cramping. The century is long enough that pure water without electrolytes can lead to hyponatremia (low blood sodium).
