What's in the bundle
Two fuels. One bottle.
Going the distance? Give your engine the fuel it needs to keep firing.
The Rocket Fuel Bundle combines our HICARB drink mixes with Lactate Shuttle to help fuel longer efforts and support sustained performance. It's the perfect combination for endurance athletes looking to keep the tank topped up when the miles start to stack up.
Carbohydrate fuel. 1:0.8.
HICARB
50g carbohydrate per sachet
HICARB uses a 1:0.8 glucose-to-fructose ratio, so it uses two transporter pathways and your body can process more carbohydrate per hour.
Choose Mango or Peach for your 10-pack.

How to use them together

Practise in training
Try HICARB and Lactate Shuttle in your longer training sessions first, so you know the amounts and timings that suit your gut. Always follow the rule: Nothing new on race day.
-
Fuel before you start
Take 1 HICARB sachet 30 to 60 minutes before a hard session or race, mixed with 300 to 500 ml of water.
-
Keep fuelling during
For efforts over 60 to 90 minutes, take 1 to 2 HICARB sachets per hour, and use your bodyweight serving of Lactate Shuttle as your second fuel source once per effort.
