How to Use Perpetuem Solids for Long-Distance Endurance
by Steve Born
Perpetuem Solids are chewable endurance fuel designed for running, cycling, triathlon and other activities lasting more than two hours. They provide a portable way to add calories when carrying bottles or mixing powdered fuel is impractical.
Each tablet provides approximately 33 calories, while three tablets provide 100 calories, 20g carbohydrate and 3g protein.
When Should You Use Perpetuem Solids?
Perpetuem Solids are particularly useful during:
- Long-distance cycling and gravel events
- Ultramarathons and long trail runs
- Half and full-distance triathlons
- Hiking and multi-day endurance events
- Any session lasting more than two hours
They can be used alone, but most athletes use them alongside liquid fuel, gels or sports drinks to add calories and provide a change in texture.
How Many Perpetuem Solids Should You Take?
Many athletes begin with approximately 120–180 calories per hour, adjusting their intake according to body size, intensity, conditions and personal experience.
One practical hourly combination is:
- 1 Hammer Gel: Approximately 90 calories
- 1–2 Perpetuem Solids: Approximately 33–67 calories
- Total: Approximately 123–157 calories
Always test your fuelling plan during training before using it in an important event.
How to Chew Perpetuem Solids
The tablets are deliberately larger than conventional energy chews because each tablet provides approximately 33 calories.
For easier consumption:
- Break each tablet into halves or smaller pieces
- Chew half to one tablet at a time
- Consume water after each portion
- Eat during easier sections of your session
- Avoid chewing during hard climbs, sprints or technical sections
Perpetuem Solids are not intended to dissolve in water. Anyone with dentures or delicate teeth should use caution.
Why Use Solids Alongside Liquid Fuel?
After several hours, athletes often want a break from consuming only drinks or gels. Perpetuem Solids provide a chewable option without requiring sandwiches, bars or other foods that may be inconvenient during exercise.

Perpetuem Solids for Running, Cycling and Triathlon
Running: Carry the tube in a running vest and consume small pieces with water at aid stations.
Cycling: Keep the tube in a jersey pocket and use the tablets to supplement bottle-based fuel.
Triathlon: Use Solids during the cycling or running sections when carrying additional premixed bottles is impractical.
Perpetuem Solids are most effective when included in a fuelling plan that has already been tested during training.
