Four-time World Ironman champion and one of the greatest triathletes of all time explains why she joined us at 33
"I started using 33's products and wanted to team up with a company that thought the same way as me - our philosophies matched. I was sick and tired of reading a list of ingredients I didn't understand, in sports nutrition and in my daily life.
"I read a lot more about the research that had been undertaken to justify the sports nutrition people were using and I found it to be somewhat hollow. I also became increasingly concerned about the number of people who have had to go to the toilet in the bushes [during races], how many people have had cramps, how many have vomited. That's not natural, it's not normal and it's not part of sport"
