Top tips for Energy & hydration on the Bike during the Fred Whitton challenge

You're about to hit 113 miles and 3,000m of elevation on the most grueling hills in the UK. To make sure you feel and perform your best it's important to fuel your body by eating the right foods. Especially on tough rides like this. Fuelling right during the race is all about balance and thinking ahead. Checkout some of our top tips below and you can download our full fuel guide.

1. Breakfast / Healthy Balanced Diet is Key! 

Our advice would be to eat 2-4 hours before you start. This should be predominantly carbohydrate based. Fruits, porridge, oats, toast, pancakes and other complex carbs. Some Protein is also important found in yoghurts and eggs. Avoid black pudding, sausages and bacon. Our simply delicious superfood cereal Bar makes for a great addition at breakfast with 40g of Carbohydrate and 5.6g Protein here.

2. How many carbs per hour for the Fred Whitton?

During exercise: 30-60g of Carbohydrate per hour for rides over an hour. Energy Bars, Gels and bananas are all great options.
top-tip! Try using an Isotonic sports drink such as KMC ISO MIX which provides energy and hydration every time you drink. It's much easier than trying to eat on the go.

3. Hydration & electrolytes strategy (before + during)

Start Early, even before you get on the bike keep drinking regularly every 10-15 mins. Once you're on the bike, do the same thing. Little & Often! You can follow our article on why hydration is so important and how to measure it here. Our sports drink KMC ISO MIX, mixes easily with just 500ml of water to provide you with all four essential electrolytes required by the body.

4. Try Energy Gels 

They're designed to be easy to open and use - just like fluids, you should be able to consume your fuel with your gloves on mid ride. Energy gels are an ideal functional product for this purpose and provide more than just an instant energy boost. They provide longer-lasting energy and hydration with essential electrolytes. KMC NRG GEL's can last up to 90 minutes.

5. Caffeine for big climbs (when to take it)

Coffee, or should we say Caffeine, actually has many proven benefits. Research shows that it can help improve muscular endurance and strength, as well as it's well known benefits in reducing fatigue and drowsiness. If there's a big hill coming up or if you need something to get you going pre-ride you can grab a caffeine gel. KMC NRG GELs (caffeinated ones) contain 100mg of caffeine. Or you could try our fresh roast coffee here.

6. Recovery after the Fred Whitton (carbs + protein)

Post-workout nutrition is just as important for glycogen re-synthesis and muscle recovery, especially if you're aiming to go again the next day! Start re-fueling as soon as you can post exercise, recovery drinks such as the KMC PRO MIX provide an ideal blend of fast acting carbohydrate and proteins in this case. You can also opt for things such as milk, cereal, bagel and cheese, sandwiches with spreads such as peanut butter. 

Example Schedule:

It's important to ask yourself these questions and remember these top tips:

  • How am I going to feel in 20 mins time?
  • Big hill coming up in 10 mins? Take onboard some Caffeine Gels! 
  • Look at your route, the climbs, the descents, think about how your body will react and build a fuel plan around it.
  • Be pro-active not reactive and remember, Little & Often!

How to fuel The Fred Whitton Challenge

FAQ's

Q: How many gels do I need for the Fred Whitton Challenge?

A: It depends on how you’re hitting your carbs-per-hour target. A solid approach for the Fred Whitton is to aim for 60–90g of carbohydrate per hour (if you’ve trained your gut for it). If you use gels as your main fuel, that often works out at roughly 1–2 gels per hour. Most riders do better with a mix: ISO MIX in bottles + gels + a bar, so you’re not relying on gels alone.

Q: How many carbs per hour should I aim for on The Fred Whitton Cycling Sportive?

A: For a long, hilly sportive like the Fred Whitton, most athletes should aim for:

  • 60–90g carbs per hour if you’ve practised it in training
  • 40–60g carbs per hour if you’re newer to fuelling or have a sensitive stomach

The key is start early and go little-and-often. If you wait until you feel empty, you’re already behind.

This can come from Bars, Gels and KMC ISO MIX.

Q: What should I eat for breakfast before the Fred Whitton?

A: Keep it simple, high-carb, and low in anything that upsets your stomach. A good target is 2–3 hours before the start:

  • Porridge with honey/banana
  • Toast/bagels with jam
  • A banana + yoghurt (if you tolerate dairy)

Avoid going heavy on fibre, spicy foods, or lots of fat, which can cause gut issues later. Many riders also take a gel 10–15 minutes before the start to top up energy right before the rolling begins.

Q: Is ISO MIX enough or do I still need gels?

A: ISO MIX helps a lot because it provides carbs + electrolytes while you sip — so your bottles aren’t just water. But for the Fred Whitton’s duration and climbing, ISO MIX alone usually isn’t enough unless you’re drinking a lot and your bottles are strong. Most riders perform best using:

  • ISO MIX in bottles (steady carbs + hydration)
  • Gels for quick top-ups (before/after big climbs)
  • Bars for variety (especially early on)

Think of ISO MIX as your “baseline fuel”, and gels as your “on-demand boost”.

Q: Should I use caffeine gels on Hardknott Pass?

A: If you tolerate caffeine well, it can be a smart move — but don’t try it for the first time on the Fred. The best strategy is:

  • Save caffeine gels for the final third of the ride, or
  • Take it 20–30 minutes before a key climb (so it’s kicking in when you need it)

If caffeine makes you jittery or unsettles your stomach, skip it and focus on consistent carbs from gels + electrolytes instead.

Q: What should I eat after the Fred Whitton for recovery?

A: Your goal is to refill energy stores and support muscle repair:

  • Carbs + protein in the first 30–60 minutes (even if you don’t feel hungry)
  • Then a proper meal later

Simple ideas:

Also: keep sipping fluids and electrolytes after finishing — you’ll often still be playing catch-up on hydration.
