Frequently Asked Questions
- When should I use the GU Roctane Ultra Endurance Gel 24-Pack during a ride?
- The GU Roctane Ultra Endurance Gel 24-Pack is best used to fuel effort rather than fix a bonk that's already happened, so most riders start taking it around 45-60 minutes into a ride and continue at regular intervals through longer efforts. Always try new nutrition like this on a training ride first, never for the first time on race day, so you know how your stomach handles it.
- Is the GU Roctane Ultra Endurance Gel 24-Pack suitable for vegans or those with dietary restrictions?
- Check the ingredients label on the GU Roctane Ultra Endurance Gel 24-Pack for full allergen and dietary information, as formulations can change between batches. GU Energy Labs lists allergen and dietary suitability directly on the packaging, and our team can help you find an alternative if the GU Roctane Ultra Endurance Gel 24-Pack doesn't suit your needs.
- How long does the GU Roctane Ultra Endurance Gel 24-Pack keep, and how should I store it?
- The GU Roctane Ultra Endurance Gel 24-Pack keeps well when stored in a cool, dry place away from direct sunlight, with a shelf life typically printed on the packaging by GU Energy Labs. Once opened, single-serving formats like this are best used within the ride they're opened for rather than saved for later.
