Most athletes fall into one of three traps. Some burn through carbohydrate far too early in a race because they haven’t trained enough time below aerobic threshold, so their body never properly learned to run on fat at moderate effort \u2014 carbs get used at a rate their training didn’t prepare them for. Others fuel aggressively to avoid bonking and end up with GI distress, because they’re taking in more than their gut can actually absorb while running or riding hard. And a lot of athletes just fuel at the maximum recommended rate as a blanket strategy, without ever finding out that better-targeted training could reduce how much fuelling they need in the first place \u2014 and let them race faster on less.<\/p>\n
This service is built to find out which of those is actually happening to you, and fix the right one.<\/p>\n
Who this is for<\/p>\n
Endurance athletes \u2014 single-discipline or multisport \u2014 who want a race fuelling strategy built from real physiological data specific to each sport they race, not a generic carbohydrate target applied the same way regardless of what your body’s actually doing during the effort.<\/p>\n
What’s included<\/p>\n
– CPET testing (running and cycling) \u2014 resting metabolic rate and threshold testing in each discipline you race, with particular attention to what’s actually happening at your specific target race pace or power, not just a generic threshold number.
\n– Swimming \u2014 resting metabolic rate is still measured, but a lactate test protocol in the pool replaces CPET, since a gas-exchange mask isn’t practical in the water. Same rigour, adapted to what the discipline actually allows.
\n– For multisport athletes, this means testing across all disciplines you race \u2014 a genuinely more complex analysis than a single-sport fuelling plan, and treated as such rather than simplified down.<\/p>\n
What the model does<\/p>\n
Your results feed into a proprietary model that profiles your energy expenditure at race effort, and your starting glycogen and fat availability \u2014 separately at the muscle groups actually doing the work, and in the liver, since these deplete differently and play different roles during a race. From that, it determines what you genuinely need to fuel during racing, capped at up to 90g of carbohydrate per hour \u2014 the established practical ceiling for absorption \u2014 and then adjusted down further for how much of that target realistically can’t be absorbed while the relevant muscles are also working and competing for blood flow. This isn’t a fuelling number handed down from a general rule; it’s built from what your body can actually do.<\/p>\n
What this is honestly missing: the effect of accumulated fatigue on fuelling \u2014 how your fuelling needs and tolerance shift as you fatigue over the course of a long race isn’t captured here. That gap is addressed by our separate Fatigue Resistance Test, which is worth adding if you want the complete picture rather than a snapshot at fresh effort.<\/p>\n
What you get<\/p>\n
A fuelling strategy that doesn’t just tell you what to eat \u2014 it tells you whether your target race pace is genuinely sustainable for the full distance with sensible fuelling, and if it isn’t, what needs to change in training to make it achievable. For most athletes, that’s the real finding: not a bigger fuelling plan, but a clearer picture of whether the problem is fuelling at all, or training that’s left them dependent on more carbohydrate than they should need.<\/p>","protected":false},"excerpt":{"rendered":"
Most race fuelling advice is generic \u2014 “take 90g of carbs an hour” \u2014 and ignores what your body can actually absorb while the muscles doing the work are competing for the same blood supply your gut needs. This service measures your real metabolic demand in every discipline you race, models your actual glycogen and fat availability at the muscle and in the liver, and builds a fuelling plan capped at what you can genuinely absorb under load \u2014 not just what a generic number says you should eat.
