Tidal Force Ultra 100

Last Tide Standing Backyard Ultra

Is an Ultra for Anyone and Everyone!

Think you can't do an ultramarathon? The 6.7km loop is designed to be achievable, even for beginners, as long as you're consistent. It’s the ultimate, forgiving endurance event—you’re only ever an hour away from your crew, your chair, and your food.

Its Simplicity is its Charm

The format is simple, every hour, on the hour, a bell rings. You have 6.7km to get back, or you're out. It’s not about speed; it's about consistency, pace, camaraderie and endurance. It’s a race with no predetermined distance or finish line. It only ends when there is one person left standing.

A Location Like No Other

Located in the heart of the Maritimes, the course is Atlantic Canada’s first true 6.7km “Loop” Backyard Ultra! Situated in both the town of Riverview & the city of Moncton, the trail circles a section of the mighty Petitcodiac River. On the Riverview side there are loads of amenities. While the Moncton side is just you and nature. While running this course, you will traverse two bridges, two parks, two boardwalks, one beer garden and a world-famous river, all while being afforded an almost unobstructed view of the whole course. Which means your crew, family and friends can follow your progress from almost any viewpoint.

Nowhere Else on Earth

It’s the only place in the world where you can participate in two races at the same time. You can be running the backyard ultra while racing the tidal bore at the very same time! And if that’s not enough, It’s the only Backyard Ultra in Canada, where the entirety of the course forms part of the world’s longest trail, the TCT (Trans Canada Trail). We would argue that it's one of the most Canadian of all Canadian Ultra courses! But don't take our word for it, come decide for yourself.

Because in our Backyard -

It’s easy, until it’s not.

À PROPOS DE LA COURSE DE NUIT ÉLECTRISANTE

La Course de nuit électrisant est une activité annuelle au profit du Centre de santé du sein du Centre hospitalier universitaire Dr-Georges-L.-Dumont. Chaque année, environ 550 participants costumés se rassemblent. Ensemble, ils marchent et courent pour la cause de la santé du sein qui leur tient particulièrement à cœur.

Toute la communauté est invitée à s’inscrire et se joindre à la 12^e édition de la Course, qui aura lieu en nouveauté au Parc Rotary St-Anselme à Dieppe, le vendredi 4 juin 2027.

Les fonds recueillis sont utilisés pour financer l’amélioration des services offerts aux patientes du Centre de santé du sein du Centre hospitalier Dr-Georges-L.-Dumont de Moncton.

Le Centre offre un programme complet pour la santé du sein, incluant la prévention, le dépistage et le diagnostic précoce pour toutes les femmes référées. Grâce à une approche intégrée, les patientes bénéficient de services offerts par une équipe multidisciplinaire œuvrant ensemble, sous un même toit, dans un environnement à la fois accueillant et innovateur.
