Endurox R4: Recovery Nutrition for Runners and Cyclists
By Best Nutrition - Singapore · · 2 min read

Quick answer
Endurox R4 is a recovery drink with a 4:1 ratio of carbohydrate to protein, designed to help endurance athletes replenish glycogen and support muscle recovery after long sessions. It is most useful after runs, rides or races lasting more than about 60 to 90 minutes, or when you train again within 24 hours.
Why carbohydrate matters for endurance recovery
Long runs and rides drain your muscle glycogen, the stored carbohydrate your body uses for fuel. Replacing it quickly matters most when you train again the next day. Adding some protein alongside carbohydrate supports muscle repair.
How to use Endurox R4
- Drink it within about 30 to 60 minutes after a long or hard session.
- Mix with cold water; chilled drinks are easier to get down after training in the heat.
- Follow up with a balanced meal a few hours later.
Who it suits
Marathon runners, cyclists, triathletes and team-sport players training multiple times a week get the most from a carbohydrate-protein drink. If you lift weights or train for less than an hour, a regular protein shake is usually enough.
Frequently asked questions
Is Endurox R4 good for weight loss?
Endurox R4 is designed for recovery and contains a significant amount of carbohydrate, so it is not intended as a weight-loss product.
Can I use Endurox R4 after a gym session?
You can, but it is best suited to long endurance sessions. For shorter strength workouts, a protein shake is usually sufficient.
