I am starting to ride with a bunch of cyclists doing on average 40 to 50k. My personal average is around mid 30s to 45k/hr. Aside from proper training, exercise and leg muscles, what food do you recommend to give you a quick energy boost to be able to keep up with the bunch? I was told Mars Bars are quick energy sources, but high in the bad stuff. Any other more natural recommendations? Thanks

    The traditional food is bananas. They work well, if you like them. They come in a handy container too - bite off the top and squeeze from the bottom. – andy256 Aug 28 '14 at 1:54

Some personal thoughts/opinions:

  • If you're not riding much longer than an hour or so, you might not need much. Perhaps a sports/electrolyte drink that contains sugars will suffice and be convenient.
  • I use mainly cheap gel bars for a sugar hit, but they get quite boring and eat away at your teeth. Flapjack, oats, etc are good for a bit of variety but perhaps more appropriate for longer rides as they release energy slower.
  • Cereal bars can be quite dry and difficult to get down especially if you're a bit dehydrated.
  • Something with caffeine may be of benefit (caffeine on its own doesn't have energy, but it can give you a boost). I'd drink some strong coffee before the ride. Caffeine has a half-life of approximately 5 to 6 hours.
  • Trial and error is key!
  • Welcome to Bicycles. The OP was asking about foods, not drugs. Caffeine cannot supply energy. – andy256 Aug 29 '14 at 9:22

    Ridiculous. You down-voted my answer because I suggested "something with caffeine" as just one part of my answer? "Something" referred to a caffeinated gel or similar. Caffeine gives you a boost, which is what the OP is looking for and therefore a relevant part of my answer. It's not like I suggested injecting an amp of caffeine during the ride instead of ingesting something. – adey_888 Aug 29 '14 at 9:50
  • Look on the bright side: I explained why I down voted, so you know what to improve. Other people may not think the same as me and upvote. – andy256 Aug 29 '14 at 10:39

    The bright side is that your "explanation" demonstrated that you did not read my post in its entirety. Other people are very welcome to go ahead and upvote - there is nothing wrong with my answer. – adey_888 Aug 29 '14 at 10:58
  • I see someone else agrees with you. That's how it works. You can check out examples of good answers in almost anything written by Kibbee, Batman, mattnz, or Mσᶎ. – andy256 Aug 29 '14 at 11:43

I am not sure you are after "The quickest Boost food" - seems the problem you have is likely to be over an extended period. If your problem is say "they leave me behind up big hills" then maybe a "boost" is what you are after, but if its just keeping up over the duration of the ride, quick boost food is not good.

The problem with the likes of Jelly beans, honey etc is the quick boost is followed by an energy crash - often of disproportionate proportions to the boost you got. These sources have a place - but generally should only be used when the finish line is in site and only when you know how the affect you.

Bananas, energy bars and gels are usually better as they have more complex carbs that release the energy over a longer time and reduce the effects of the low sugar crash. These should be used before you feel the need for them, so the energy is there when its needed, and ideally consumed regularly in small amounts - if needed set a repeating timer and eat when it beeps - every 10-20 minutes.

As everyone is different, the best advise is to try different foods and choose one you like, and different frequencies and amounts - most people do better on small and often. Do this before you need it - some gels make me want to vomit when working hard, others work really well for me. If you have one that disagrees with you, best its not when you are not trying to keep up with a bunch.

  • when the finish line is in site speaking figurativevly, right? I feel that a chocolate bar provides energy for at least an hour. – Vorac Aug 28 '14 at 16:19
  • Chocolate is high in fat with a bit of sugar - the fat keeps you going longer, the sugar gives you a boost - so chocolate does not fit into the Jelly bean (simple sugar) food group. – mattnz Aug 28 '14 at 20:37

What are the other cyclists in your group eating? I go out for similarly long rides, and most people don't eat anything on the ride. I would say to make sure you are well fed (but not overly full) before the ride starts, and you probably won't feel the need to eat something for the ride. 50 KM at an average speed of 35 km/h will mean that the ride is over in an hour and a half. Bring a bottle with Gatorade or similar to keep your electrolytes up, and possibly another bottle of just water for those times when you feel like just having water.

Also, if you are going to eat something, eat small amounts on a regular basis, and don't wait until you feel like you need more energy. By that time it's already too late. The same goes for water. Drink before you start to feel thirsty. Get to know your own body and how much water/food you're going to need for a particular length and difficulty of ride so that your body doesn't end up with a deficit during the ride.


Mars Bars are not that great for cycling. Yes, they have quite a lot of calories, so will give you some energy. But most of that is simple sugars, so it may be a quick energy boost, but soon followed by an energy crash. Also Mars Bars have quite a lot of fat (about 17g per 100g), so this can not be easily digested while cycling hard - it could just make you sick.

Mars Bars are not very practical either. On a warm day, a bar in your back pocket will probably melt, so become rather messy and difficult to eat.


Energy gels such as GU Energy gels are a pretty common quick acting energy source.

For a more natural source, you could try honey

  • My understanding is that GU Gels take longer than jelly beans for example because of their dissolving factor. Being a gel, they simply take longer to dissolve in your system and act more like pasta than anything else. Honey is a great idea though! – Fandango68 Aug 28 '14 at 1:53

It's about keeping your energy up NOT about somehow generating 5kmph more from food. You'll go faster through training but it won't help if you bonk half way through a ride. I tend to "fuel" up before a ride then eat as I go along; usually rice cakes or cereal bars. For a bit of emergency energy if I'm flagging I'll go with a gel (some give me cramps tho) or something like shot bloks. However I can say with confidence that if I'd eaten properly as I rode, I'd never have needed them.

As an aside, if your AVERAGE speed on a solo ride is 35-45kmph, I'd start racing pretty; that is pretty quick.

  • My average is around 40 to be more precise. Yes that's fast by most average rider standards, but a lot of the guys here are faster believe me. I have not asked them yet what they eat though, but that is a good start. – Fandango68 Sep 1 '14 at 3:51
  • Given the average speed of a pro peloton on a flattish stage is around 40-45kmph that's impressive. – atlaz Sep 2 '14 at 7:30

Skratchlabs has made a series of youtube videos for lots of types of food for different types of energy. You may want to thumb through them in order to find something which works for you (your stomach may not agree with everything).

One thing I particularly like about the Skratchlabs videos is that they have a nice way of packaging real foods in foil so you can eat while riding.

Cliff makes Cliff Shot Bloks and companies make similar energy gel type products which you may want to try as well.


I typically eat Powerbars or gels like GU if I need more intake on the bike. Additionally, I have a electrolyte mix like Cytomax in my water bottles which keeps me ingesting salts and calories. Bananas are also great, though I eat so many post-ride that I typically don't eat them on the bike unless it's a really long ride.

If you're slowly eating throughout the ride, I see no reason to need a "quick boost".


I find that on a longish ride, if I grab a chocolate milk at a quick stop at a convenience store, it keeps me ahead of the dreaded bonk.
