The Story
Brussels, Belgium. Olympic-distance triathlon. The 1500m swim sends you into cold open ocean at 15°C — bracing — the kind of cold that sharpens focus. The bike covers 40km of gently rolling terrain with 190m of climbing — enough to test your legs without breaking them. A 10km rolling run through Brussels that punishes anyone who left their legs on the bike. Humidity sits around 75% — the air itself feels like resistance. What makes it memorable: Art Nouveau facades, waffle-scented air, a bilingual crowd that cheers in both French and Flemish. It's a race that rewards fitness and grit in equal measure.
"The swim in Brussels wakes you up. The bike tests you. The run shows you who you are."
What It Feels Like
A olympic course that reflects Brussels: EU-capital formality hiding a chaotic heart. It suits a wide range of athletes — accessible enough for a strong first-timer, honest enough to challenge a veteran. Race it once and you'll understand why people return.
🏊 The Swim
A 1500m ocean swim in cold saltwater at 15°C. Shore break can add a physical challenge on entry and exit. Sight off the buoys — the open water offers few reference points.
🚴 The Bike
40km of rolling terrain with 190m of climbing. Short rises break your rhythm; descents reward those who corner confidently. It's a bike course that asks for constant attention — no long steady stretches to zone out.
🏃 The Run
A 10km rolling run through Brussels. The undulations are gentle but relentless — each small rise costs more than it should on tired legs. Keep your cadence quick on the ups and let gravity help on the downs.
💡 Insider Tips
- → Water temperature averages 15°C. Acclimatise with cold-water swims in training — your first 200m will set the tone for the entire race. A neoprene cap under your swim cap makes a real difference.
- → Winds averaging 18 km/h are common. On the bike, ride steady power rather than steady speed. The headwind sections will slow you; the tailwind sections will reward patience.
- → Ocean conditions can change on race morning. Practice dolphin-diving through shore break and body-surfing to shore on the return. Sight frequently — ocean swells can push you off-line without you realising.
