Triathlons push athletes' bodies to the limit, especially competing internationally. Add the chance of suffering an epileptic seizure and the task seems almost impossible.
But former half-ironman champion Michael Poole refuses to let the condition, which he's had since he was 18, hold him back.
Poole is back in the saddle after suffering a grand mal seizure during Chicago's Life Time Tri Series triathlon in August last year.
The incident shot the 24-year-old's confidence and made him question his future in the gruelling sport.
"It took me quite a while to get my confidence back and want to push my body, I was quite fearful," he said.
