Fuel you'd put in your body every day for 20 years.

I'm Greg Collins. I'd built my training around the long game — Oura-tracked sleep, daily aerobic and anaerobic work, sauna for recovery, eating well most days. It paid off in competitive rides and runs with friends. The one thing that didn't fit was race-day fuel: every gel I picked up was an ingredient list I wouldn't touch the rest of the week. I don't go to a lab for my daily food — why would I make an exception for the rides that mattered most?

I went looking for something that wasn't engineered in a beaker and landed on maple syrup. The catch: the maple-based products on the shelf weren't built for performance. So I built one that was — with Karine, Rachelle, and Max, who joined to take it from an idea I had on a long ride to a product on the shelf.

— Greg Collins, Founder. Sève Endurance — natural fuel that performs.

Sève was born from a simple frustration: most energy gels prioritize short-term performance at the expense of long-term health. As endurance athletes ourselves, we wanted fuel that respected both.

We looked at the ingredients in traditional gels — maltodextrin, artificial flavours, chloride-based salts — and asked a different question: what if we could create fuel that worked with your body, not against it? That question led us to maple syrup. Canadian maple isn't just a sweetener — it's a complex carbohydrate source with natural minerals and antioxidants. Pair it with citrate-based electrolytes and magnesium malate, and you get a formula that's both effective and clean. Something fundamentally different.

So we built it ourselves. A team of four, working directly with athletes, testing every batch until we got it right.

Canada produces 71% of the world's pure maple syrup. Quebec produces nearly all of that. It's the most iconic agricultural product of the place we live, and the foundation of every Sève formula.

Our maple is sourced from Quebec producers who've been perfecting their craft for generations — sugar shacks tapped by families who've been doing this longer than the gel category has existed. Single-origin, grade A, traceable from the tree to the pouch. When you train on Sève, you're fueling on Quebec maple — not a global supply chain of corn-starch derivatives.

We're proud of where it comes from. We think you'll taste the difference.

The athletes who keep coming back are the ones who pay attention. Marathoners chasing PBs. Trail runners who've blown up at hour four on a synthetic gel and refuse to go back. Cyclists doing 200-km gravel weekends. The kind of people who read ingredient lists and ask hard questions.

“Sève helped me PB at Boston by 3 minutes.”

The gels are smooth, the electrolytes don't upset my stomach, and I felt strong the entire race.
— Angela Shoniker, Boston Marathon (3:11 PB)

“Easy to take down, even at hour four.”

I actually look forward to my long runs now because I know I won't be fighting my stomach.
— Emily C., marathoner

“Caffeine without the crash.”

Did a long trail hike with Focus and stayed sharp the whole way through.
— Gayle Fransham, trail runner

Performance and health aren't trade-offs. The best athletes aren't just fast — they're resilient. They train for decades, not seasons.

Every decision we make at Sève is guided by one principle: would we want to put this in our own bodies every day for the next 20 years? Natural ingredients. Science-backed formulations. Complete transparency. No compromises.

Sève is for athletes who think beyond the next race. You're training for decades of performance — marathons at 50, ultras at 60, centuries at 70. You care what goes into your body because you know it compounds over time.

You read nutrition labels. You ask questions. You're skeptical of marketing hype and want products backed by real science and real ingredients. You're as likely to track your HRV as your pace. You'd rather pay more for fuel that won't wreck you in a decade than save five dollars on the same maltodextrin everyone else is selling.

If that's you, Sève was made for you.
