These are just brilliant at giving a quick, tasty hit of energy.

I love Voom and use them for cycling and running. I get stick of gels and alternate liquids with these bars, the flavours are great and I use the caffeine ones towards the end of ultra races when I need the extra oomph. There are enough favours not to get bored and I always have these in my race pack in case I have a dip as they work quickly and without any side effects.

I used the raspberry and blackcurrant throughout my race (South Downs way 50) and managed to keep my hydration levels exactly where I wanted them to be! I walked away with a podium finish!!

Amazing

Was introduced to these at the great north 5k swim and really helped give me the extra boost I needed for the final lap! Have also been using for triathlon training and they are so easy to digest and not sticky

Game changer

I genuinely think VOOM bars have been a changer for me. They're tasty, they contain the nutrients and energy I need and they're so much easier to eat than a gel. Absolutely brilliant!

The best fuel for serious runners

The best fuel for serious runners. I'm slowly upping my mileage as I am marathon training, and these Voom bars have really helped me. I take 1-2 cubes at 5km, 15km, 20km, 25km and 30km and slowly working towards running that marathon!

Flavour and ingredients

Love how these bars have real active ingredients. Beetroot has got to be one of my favourite foods, and this bar tastes like a grown up chocolate bar, love it

Banging product

Genuinely love this bar - hits the spot for near instant energy, tastes great, easy to digest during high performance, good beta alanine boost as an extra.

Your Personal
Nutrition Calculators.

Five free calculators that turn your weight, event and effort into an exact race-day plan — dose, timing and all.

Bicarb Lactic buffer Nitrate Oxygen efficiency Electrolyte Hydration Carbohydrate Energy & fuelling Protein Recovery

Sodium bicarbonate buffers the acid produced in high-intensity efforts, delaying that burning-legs feeling in events from 1–10 minutes or with repeated hard bouts.

  • Personalised dose from your body weight
  • Capsule count & split-dose plan
  • Optimal timing before your event
Get my bicarb plan

Dietary nitrate from beetroot boosts nitric oxide, improving blood flow and muscle efficiency — hold the same pace at a lower oxygen cost.

  • Daily nitrate target for your body weight
  • Loading protocol for race week
  • Timing your final dose before the start

Sweat rate and sodium loss vary hugely between athletes. Match your fluid and electrolyte intake to your conditions, duration and sweat profile to beat cramp and fade.

  • Fluid & sodium targets per hour
  • Adjusted for heat, duration & intensity
  • A practical race-day drink plan
Build my hydration plan

Your muscles only store around 90 minutes of glycogen. Fuelling with 30–90g of carbs per hour maintains blood glucose and delays fatigue — under-fuelling is why so many fade late in a race.

  • Carbs per hour for your duration & intensity
  • Whole-session fuelling & energy totals
  • Adjusted for a trained, high-carb gut
Build my fuelling plan

Protein taken soon after exercise provides the amino acids to repair and rebuild muscle — around 0.25–0.4g per kg of body weight maximises muscle protein synthesis and speeds recovery between sessions.

  • Post-session protein target from your weight
  • Matched to easy, standard or hard sessions
  • Carb pairing & 30-minute timing window
