When it comes to using new technology I always believe that you need to leave your preconceptions at the door and try and look at a new product with an open mind. The thought of placing a device in my nose is not something that I had ever tried before and to be honest I was a little apprehensive. I am very much a free runner and try and limit the amount of equipment I take out on the trail with me.
Now this is not a new company, Rhinomed have been around for quite some time and have a great following in the cycling world. Their products have been endorsed by world champion triathletes all the way to yellow jersey winners so this is not a gimmick. They are proud of these products and they proclaim to allow you to take in 38% more air per breath.
