Olivia and the rest of the Go Green Racers are headed to Bunchgrass Hills Conservation Area, a beautiful grassland in British Columbia. For this leg of the race, they need to investigate a creek and figure out why it’s drying out.

Having studied this in school, Olivia feels ready for the challenge, but Ryan, who thinks science is for boys, is sure he’ll leave Olivia in the dust. Can Olivia prove him wrong?

This episode was made in collaboration with Nature Conservancy Canada and was proudly supported by Teck.

The Go Green Race heads back to Canada, where the final four racers arrive at a local, organic farm outside Vancouver for a high-stakes cooking challenge. The racers must forage for ingredients and create a dish worthy of a celebrity chef. 

Olivia thinks she’s finally got the perfect recipe, but things don’t always go according to plan. Will she be able to adapt, or will she be sent home?

In this leg of the Go Green Race, we head deep into the rainforests of Suriname, where racers must track down the animal “engineers” that help keep the forest healthy and thriving. 

But with a surprise double elimination looming and Ryan pushing her buttons, Olivia has an even bigger challenge: figuring out what kind of racer she wants to be. With only a handful of racers left, Olivia’s about to take her biggest gamble yet.

The Go Green Race moves on to the bustling city of San José, Costa Rica, where the racers must prove that green claims are actually true – because anyone can slap a label on something. Olivia heads to a vibrant market to track down real evidence of sustainability, but she quickly picks up an unwanted shadow who copies her every move. 

Between a tongue-wagging rival, a scarlet macaw with sticky fingers and an overturned fruit cart, the market is anything but a break from the jungle. But just when Olivia finally starts making decisions for herself instead of reacting to everyone around her, one impulsive choice could change everything – and Ryan saw the whole thing.

The race swings to the Monteverde Cloud Forest in Costa Rica, where the racers must zipline in, tread lightly, and photograph three examples of how this rare ecosystem holds itself together – without leaving a single trace they were ever there. One wrong move and you're out on the spot, no second chances! Olivia is already rattled before the challenge even begins, thanks to a certain someone on the zipline platform, and when she decides to get even, the consequences ripple further than she ever expected.

Friendships are tested, tempers flare and deep in the mist of the cloud forest, Ryan lets something slip that changes how Olivia sees him entirely. Some places have a way of making people get honest – whether they're ready to or not.

Just when Olivia thought her race was over, a cheating scandal turns everything upside down! The remaining racers head to Ranganathittu Bird Sanctuary in Mysore, India, where the challenge is all about feeding the birds – but only if you can figure out exactly what they eat and where they find it.

With the animal shelter back home on the line and the finish line finally in sight, Olivia has never had more reason to get it right.

The race lands in India's Molai Forest – a forest planted single-handedly by one man over decades – for a plant-tracking challenge that takes a sharp turn when Hugo wanders straight into Bengal tiger territory. Olivia has to choose between her own race time and going after him, all while a mysterious shoe-swapping Ivy keeps popping up in places she shouldn't be able to reach. 

And just when Olivia thinks her race might be over, news from back home makes winning matter more than ever before.

The race lands in Kenya's Loisaba Conservancy, where the stakes just got enormous – literally. With only 20 racers left and just 10 markers hidden across the savannah, half the field is about to go home. Olivia follows a herd of elephants across cracked, dry ground to track down her marker, while Ivy's mysterious field researcher advantage raises more questions than it answers. 

The grand prize is finally revealed, and it's worth racing for. But is Olivia imagining things – or is something a little strange going on with Ivy?

Olivia arrives in Neustadt, Germany with chicken feathers in her hair and a lot of explaining to do. The Go Green Racers tackle a high-stakes recycling challenge inside a real sorting facility, where one wrong item can ruin an entire batch. And one distracted racer ends up trapped in a fenced compound with a very confused wild boar. And Ryan. 

When Olivia and her least favourite rival find themselves cornered together, they're forced to ask a question neither saw coming: what if they've been assuming the worst about each other all along?

Olivia arrives in Amsterdam – a city built around outsmarting water – and discovers that sometimes the key to staying afloat is just going with the flow. Literally. When the racers tackle a series of floodgate checkpoints, Olivia loses her phone to a canal (thanks, Emma) but gains a new friend mid-panic attack

Will her streak of accidental brilliance carry her to the finish line – or will the city that's spent 800 years holding back the sea finally teach her when to let go?

The Go Green Race rolls into Copenhagen – a city so obsessed with bikes it practically has wheels instead of sidewalks. The challenge: follow cycling routes through eco corridors, crack clues about Denmark's national bird and make it to a protected canal zone before a drawbridge cuts off the finish line. For good!

There's just one problem. Olivia really does not want to get on a bike.

Can she find her rhythm in time – and can a new ally, a very showboaty Ryan, and a tight deadline lead to one of the most dramatic finishes yet?
