Allergen Information:
No major allergens declared; manufactured in a facility that handles common allergens – check packaging for sensitive individuals.
Who it’s for:
Perfect for runners, cyclists, triathletes, or anyone needing steady carbs on the go – without the mess or funkiness of gels.
What it does:
Delivers rapid, dual-source carbs for energy, customisable sodium for hydration balance, and optional caffeine for focus – all in a compact, chewable cube.
How I’d use it:
Pop 3 chews 15 minutes before activity, then another serving every 30–45 minutes during long sessions – paired with sips of water to keep digestion smooth.
The Science:
Raisins & Sport Chews Improve Carbohydrate Oxidation and 5km Time Trial Performance
Study: A randomised trial in trained runners compared the effects of ingesting raisins, commercial sport chew products, or water during an 80-minute run at ~75% VO₂ max, followed by a 5km time trial. Metrics tracked included carbohydrate oxidation, blood glucose levels, and performance outcomes.
International Journal of Sport Nutrition & Exercise Metabolism (Too et al., 2012)
https://pubmed.ncbi.nlm.nih.gov/22704463/
Both sports chews and raisins significantly elevated carbohydrate oxidation rates and enhanced time-trial performance (≈1 minute faster) compared to water. Gastrointestinal discomfort remained minimal, making chew-style carbs like Clif Bloks a proven endurance fuel option.
Meta-Analysis: Carbohydrate Supplementation Enhances Endurance Performance
Study: A meta-analysis of competition-based trials comparing carbohydrate supplementation (typically 6–8% concentration) against placebo or no supplementation, on time-to-exhaustion and mean power output during prolonged endurance exercise in trained male cyclists.
Journal of the International Society of Sports Nutrition (Pöchmüller et al., 2016)

Carbohydrate ingestion during endurance exercise significantly improved performance – reducing time-to-exhaustion and increasing power output compared to no supplementation – lending strong support to using Clif Shot Bloks as an effective fueling strategy during prolonged training or racing.
