Fuel for the first hours. Fuel for the road.
One system covers the whole session: Power Fluids in your bottle for steady carbs and salt, pastilles in your pouch for fuel you actually look forward to. Together, roughly 1,600g of carbohydrate — 20+ hours of properly fuelled training.

Your first box lands

Train. Fuel. Repeat.
Mix the fluids, load the pouch, go long. The kit is reusable — the fuel is the only thing that runs out.

Reloads arrive on schedule

"FTP Endurance Fuel was built to create a better fuelling experience — simple, effective, and designed for real endurance athletes."— Rob Lawrie, Founder, FTP Endurance Fuel
The System is the box packed for FTP's own long sessions: the exact fuel, bottle and pouch, reloaded on schedule so the cupboard is never the reason a long run goes short. Not for elites — for the person doing their long run at six in the morning because it's the only gap in the day.
Questions, answered straight
What exactly recurs, and what's one-off?
Every reload is the fuel: Power Fluids 900g + 1kg Energy Pastilles for £59.99. The Adventure Pouch, bottle and taster are free gifts in your first box only — they're reusable, so you only need them once.
Can I change flavour, skip a box, or cancel?
Yes — all of it, from your account, in a couple of clicks. Swap Tart Cherry for Mixed Fruit, push a delivery back a fortnight before a taper, pause for the off-season, or cancel outright. No calls, no forms, no guilt trip.
Is 6 weeks the right frequency for me?
A reload holds roughly 1,600g of carbs — about 20–25 hours of fuelled training. Training 3–4 fuelled hours a week? 6 weeks is right. Marathon block? Pick 4. Ticking over? Pick 8. You can change frequency anytime.
How much fuel is it per session?
Power Fluids mixes to your bottle at race strength, and the pastilles run about 60g of carbs per serving. Most athletes fuel 60–90g per hour on long sessions — see our fuel guides for the full protocol.
What if I only want it once?
No problem — buy the System one-time for £69.99. You won't get the Welcome Kit or the reload price, but the fuel is identical.
