CLIF Bloks Energy Chews

Taste great and easy to digest. Prefer them to gels.

I bought these as I did a Marathon at the end of last year and just find they are easier to use whilst running. It can be tempting to eat them like sweets too but I wouldn't reccomend it 😊

Great taste and easy to have mid-workout, and very easy on the stomach. I tend to take one every 10mins during a long run.

Brilliant for marathons and long training runs.

I’m obsessed with Clif Energy Blocks! These little gummies are a game-changer for my long runs, especially marathons. They taste amazing, more like a treat than something I *have* to eat while running. The flavors are so good that I actually look forward to having them during my races.

I've made them a key part of my nutrition strategy for runs over 21km. My routine is simple: one gummy every 5k, and it keeps me motivated and energized the whole way. I've never hit the dreaded “wall” thanks to these. These gummies keep my glucose levels steady, and they sit really well in my stomach, which is a huge win when you’re pushing your body for hours.

If you’re looking for a fuel option that's effective, easy to eat, and actually enjoyable, Clif Energy Blocks are a no-brainer. They've become a staple in my running gear, and I wouldn't tackle a marathon without them!

Clif Bloks are horrendously expensive at approximately 42p per blok (there are 6 bloks in each individually wrapped packet, and this box includes 18 packets, so a total of 108 bloks), but they are great quality and just right for a boost during long duration activity. We have ours for long cycle rides and in the past I have used them in marathons and marathon training. When you need a boost they are great for easily digestible and fast absorbing sugars, and the caffiene included really helps too. Each blok is chunky but a suitable size to eat, and they are smooth and easily chewable. The flavour is not strong - which is perfect for when you don't necessily feel like eating but need some rapid fuel. We keep these for the very special training sessions or events where a boost is needed.

Very handy for training & getting through the marathon

Easy to pack and eat while riding. US made so I guess they’ll be stung with a tariff

Hit the spot make a difference straight away easy to chew easy to carry

I like these energy blocks but not enough to use £45 worth in 1 month! When the package arrived the use by date on them all was the following month. This should have been clearly listed on the description.

Very good thank you , I would buy again

Work well for me during the marathon

The box we ordered came open and had less packets than stated. Be careful ordering this item!

Compact, tasty and effective

Love these for marathon training but for a box of this quantity I expected longer than 3 month shelf life. Gave half the box away to my running club as I'd never use them all in time.

Good stuff. Kept my partner going for his half Ironman

My older children use these for tennis tournaments and swear by them. They don't like gels or drinks, so these suit them well.

Perfect for long runs. Easily digestible and great taste.

Only energy supplement that didn't make me sick

Decent price & fast delivery as always

With regards to gels - this is a personal thing and these might not work for you, but for me are easy to digest and seem to give me a shot term boost quickly…

bought these loads of times would buy again. taste great and a good caffeine kick

I use these regularly as part of my marathon training. They are a fantastic alternative to gels which I just can't take.

I use these on my long rides, alternate between a bar and one of these every half hour and I can go all day. When I'm starting top flag a little, one of these 5-10 mins before a climb and you notice the difference.

Also used them for a 200km overnight ride, where the caffeine is a bonus
