Aileen Morrison (31) is a professional triathlete, and she represented Ireland at the London 2012 Olympics. She says:
'My dad had us doing all sorts of sporty, outdoorsy stuff when I was little, so exercise has always been a way of life. It's something I see myself continuing in the future and passing on to my own kids.
"Since joining with a new coach last year, I'm doing things a little bit differently. My old coach allowed me one day off a week but my new coach has recovery days instead, so I'll have an easy swim or run, but still train everyday.
"Each day is different and in a week I'll usually have six swims, four or five bike sessions, six runs and three gym visits with physio and massage as well.
"Because I'm training for up to six hours a day, I have to make sure I get enough grub, but it's important to make sure that grub has the correct nutritional content.
"Chips, chocolate and alcohol are pretty much out, but most of the time I don't want them anyway. I like eating healthy food and, if I've had a hard session, I'll have an Optimum Nutrition bar or I have emergency chocolate peanut butter bars hidden in my car.
"Sometimes I find myself craving a big pain au raisin from M&S, but if I'm training hard, I do allow myself a treat."
