What do I need to know?
Ridium's training read and the caveats before you trust the times.
Training read · Ridium AIA 323 km gravel ultra with 4,819 m of climbing demands durable endurance, calm pacing and reliable self-management across long remote sectors.
- Endurance
Build long aerobic rides and back-to-back endurance days so you can keep producing steady power after several hours on gravel.
- Fueling
Practice a simple fueling routine every 20 to 30 minutes, because the route length and remote terrain leave little room for missed calories.
- Climbing
Use low-cadence tempo work and long rolling climbs to prepare for repeated moderate climbs rather than one single decisive mountain pass.
- Technical
Include rough-gravel handling, loaded-bike cornering and controlled descending so fatigue does not make the forest and open-road sectors costly.
- Pacing
Keep the opening hours deliberately conservative and treat the later climbs and wind-exposed sections as the real test of the ride.
