The course

A walk through the plan for the River Falls building

A warped wall, swinging rigs, a climbing wall and bleachers for the parents, all under one steel roof.

Four ways to play

One course, four ways to use it. Every visit starts with a warm-up and ends with a run you couldn’t do last time.

4+

Classes start at age four, and grown-ups get a course too.

Classes

Weekly classes grouped by age and level. Coaches break each obstacle into small goals, and kids earn them one at a time.

Birthday parties

The course to yourselves, a coach running the games and a room for cake. Pick your date online.

Open gym

Drop-in hours to run the whole course, practise one move or bring a friend.

Camps

Day camps when school is out: course time, games and a long lunch.

Grip, footwork and nerve: the same skills our classes build in small steps. Every clip here is Jacob.

Why we’re building it

Small goals, big walls

Bee and Scott Furlong watched their boys, Finn and Brooks, grow braver one obstacle at a time. They love this town, they spend their weekends outdoors, and they want every kid here to get that feeling without a long drive.

That is the whole idea of the gym. Coaches split every obstacle into mini goals you can tick off: hang for five seconds, then swing, then reach. Kids leave each class with one thing they couldn’t do when they walked in, and parents get to see it happen.

Frog Run

Get the frog across the course and up the wall. Hop with the arrow keys, or swipe on a phone. Every gap you clear is one more lane, the same way our classes work.

Save your spot on the wall

When do you open?

We’re fitting out the building in River Falls now. People on the waitlist hear the opening date first and get first pick of class times.

What ages can climb?

Classes start at age four and run by age group through the teens. Grown-ups have their own classes and open gym hours.

Does my kid need any experience?

None. Every class starts with a warm-up and every obstacle has an easier version. Coaches set each kid a goal that fits.

What should we wear?

Clothes you can move in, with no zips or buckles. Most people climb barefoot or in clean, flat-soled shoes. Bring a water bottle.

Is there a waiver?

Yes. A parent or guardian signs one waiver per athlete online before the first visit. It takes about two minutes, and you can opt out of photos there too.

Can we book a birthday party?

Yes. Parties get the course to themselves with a coach running games, then a room for cake. Booking opens online when we do.

Can parents watch?

Yes. There are bleachers along the course, so you can watch every run.
