Training With What You’ll Race With: Why Precision Fuel & Hydration Matters for Ironman Ottawa

February 11, 2026

If you’re racing Ironman or Ironman 70.3 this summer, you already know that fitness is only half the battle. The other half? Getting your fuelling and hydration right — without upsetting your stomach on race day.

That’s why it matters that Precision Fuel & Hydration (PF&H) will be the on-course hydration at Ironman races, including right here in Ottawa. For triathletes, this isn’t just industry news — it’s a chance to train smarter and reduce one of the biggest risks on race day: gastrointestinal distress.

Race day is not the time to experiment

One of the most common mistakes we see is athletes showing up to a race and using hydration products they haven’t trained with. Different sodium levels, flavours, or formulations can all cause issues — bloating, cramps, nausea, or worse — especially under race-day stress.

If you’re planning to rely on on-course hydration at Ironman Ottawa, you should be training with those same products now. That’s where Precision Fuel & Hydration comes in.

Why sodium matters (especially for long-course racing)

PF&H’s PH 1000 electrolyte drink is designed for long, hot, sweaty days — exactly what Ironman racing demands. It contains a higher sodium concentration than many standard sports drinks, helping athletes better replace what they lose through sweat over several hours of racing.

For long-course triathletes, managing hydration isn’t just about drinking more fluid — it’s about maintaining sodium balance so your body can actually absorb what you’re taking in.

Hydration and fuelling: separated, on purpose

At Ironman races, hydration and calories are handled separately. PF&H provides electrolytes, while carbohydrates come from a different source. This allows athletes to fine-tune their intake — adjusting fluids and sodium based on conditions and sweat rate, without being forced to take in extra calories they don’t need.

In training, this separation gives you more control and helps reduce the risk of gut overload on race day.

The big takeaway for Ottawa triathletes

If Ironman Ottawa is on your calendar, now is the time to:

Practice with the hydration you’ll use on course
Dial in how much fluid and sodium you need
Stress-test your nutrition plan during long rides and brick workouts

Race day should be about execution, not guesswork.

We carry Precision Fuel & Hydration products in-store, and our staff are always happy to help you think through hydration strategies for long-course racing — whether it’s your first Ironman or your tenth.

Train with what you’ll race with. Your stomach will thank you as your running past Parliament towards the finish.
