24 Hour Obstacle Course Racing World Championships

Friends of ioMerino, Michael and Scott, tackled the 24 Obstacle Course Racing World Championships earlier this year. Michael is an Ear, Nose and Throat surgeon but he is also a very keen ultra competitor. He has competed in the Ultra Trail Australia three times and ran the Ultra-Trail du Mont-Blanc in Italy. Michael was looking for something different to test himself.

Scott is the founder and principal trainer at Fitness Habitat. He has set up an obstacle course in his gym and accompanied Michael on the OCR event. They competed as a team of 2 but everyone else was a team of 4 so had an upward battle. We asked Scott to tell us about his experience.

"Thanks to ioMerino founder and owner, David and our other amazing support crew, we managed to complete the full 24hrs (which has eluded me, due to teammate injuries in the prior two 24hr events I have competed in). 

This year the event only had the solo and 4 man teams, with no duo teams. In my experience, the solo usually ensures a pretty slow pace unless you are in the top 10% of the athletically gifted. The 4 man teams have enough rest, to go at the course like you're only doing it the once. Michael and I chose to run a duo team to test ourselves with pace and endurance, so we were gauging ourselves against the previous years' duo winners. Despite an old calf injury that resurfaced after my first few laps, we were fortunate to match last years duo winners lap record.  

Fitness Habitat group fitness gym in Marden SA is a fully equipped obstacle racing gym, so I felt I was fully prepared for the course obstacles. As long as you put the kilometres, hrs and right fuel and recovery methods in, I believe most will survive the distance.

Weather is something we have no control over, and in previous years that the Sydney area has been wet, cold and foggy. So if you don't show up with the right kit, in my opinion, you will not survive the race. The past few years I have always elected to race in wool, as it wicks water and keeps you warm when you are wet (and getting wet is a definite, in a race like the 24hr True Grit).

Growing up in New Zealand, we Kiwis all know that Merino wool is the best of the best when it comes to wool products. So once Michael introduced me to the ioMerino website, I was all over purchasing the items I knew would hold me in good stead for the race. Thankfully the delivery time was ridiculously fast, so I received everything in time, despite ordering so close to race day. The items I ordered definitely lived up to their reputation, at no time did I feel under equipped for the event. The kit endured the rigours of the race and remains my obstacle racing super suit for continued training and event days. Even the summer events, you will see me in it. I almost felt sorry for the guys wearing regular cotton and other gear during the event, but I was also happy to have that advantage. No doubt, they will all wise up eventually."

Fabric Guide

While Merino is an amazing natural fibre, not all Merino fabrics are created equal. At ioMerino, we make our own fabrics, using only the best quality fibres, and to very specific specifications that make the most of the natural benefits of Merino. All of them are 'Merino rich’. No cheap blends passed off as Merino. No cheaper scratchy fibres or synthetic substitutes to save money. No unethical production. And each fabric is made for a specific purpose. So if you see something with a small amount of elastase or nylon added, you can be sure it absolutely needs to be there to enhance the natural stretch and durability. 

It took every bit of our 140 years of experience in the wool industry to perfect our fabrics, but we think you’ll agree the end result was more than worth the effort.
