Get Adelaide Marathon Ready

I will always remember lining up for my very first Adelaide Marathon way too many years ago now, and I turned to the runner next to me and asked if he had any last minute advice.

“If you’ve done the training you’ll be fine” he said.
Narrator: And it was not fine. Not even close.

Outsider and nature photographer tells us about his recent adventure in Far North Queensland. And yes, he absolutely wore io every. single. day. Cold? io. Warm? io. Humid? io. Daytime? io. Night time. io.

Safari In Botswana With Outsider Jodie

About this time every year, we start changing our tune from “io is great in the cold weather” to “io is great in the warm weather” and we know some of you will be sceptical. How can one product do two different things that are literally the opposite?

Celsius Tank

Cute

I ordered one size up as advised in the product description and it fits perfectly. I love the stripes. Have not yet worn it on a run due to weather but I love wool and expect it to perform well.

Perfect T

I’ve not worn a T in my life that works like the IO. From Exmouth to Adelaide this T worked as described by the company

Universal Tee - Austrailio

Raglan Tops - Outstanding Value

Great for a cold weekend away (at Wonderland), or smart to wear at work with a Pinnacle Top. Such good quality, I bought 2 if each. The colour has not faded after 3 years wear.
