For tonight's benchmarking task, we asked each team for a short summary of their benchmarking experience.

Max and Paul Kelly: We found a cluster of benches, hit the motherload! They were at 'mental region skinny' (what three words).

Chloe and Nikki: We had a stream that was meant to be a path, didn't have wellies.

To condition check the benches, we just gave them a kick!

Val and Deborah: We went round in circles. We were meant to find somewhere called fairway, it was faraway!

Mitch and Emma: We found a bench shaped like a dragonfly, a bench shaped like a butterfly and a bench shaped like a snail.

Ben and Alaya: It was perfect conditions for running, which was good because we only had one bench.

The Barretts: There are a LOT of benches along the river.

Mel and Debs: We had to kick Vicky and Gary out of our area because they were trespassing. We also took a selfie at Mitch's house. We also ranked highlighters in order of colour preference (blue is last).

Craig and Louise: I'm glad Craig was navigating, I would have got us lost.

Vicky and Gary: I really like benchmarking, it makes running much more fun (Gary).

Amy T and Paula: Amy is a top navigator (Paula), Paula is the queen of the switchbacks (Amy).
