Liam Killeen. Liam Killeen is a rising star in cross-country mountain biking. He has raced since he was 12 and has had both successes and disappointments in that time. His worst moment so far was during a recent World Championship. His front tyre started to lose air in the last part of the race and he finished fourth. This was not the first time he'd been unlucky. In a previous race, it was raining heavily and he crashed his bike just minutes after the start. He often gets nervous before a race but thinks that this is a good thing. 'Nervous energy makes you go faster and on the day, it's all about winning. The important thing is to stay positive." Liam likes a hard race with steep climbs. 'They make all the difference. You have to be really fit to get ahead'. He also enjoys entering competitions at top levels as there are fewer riders in the race and this makes the start easier. You can get into the front group more quickly.' Liam has been chosen to go to the Olympic Games and one day he would like to win a medal. 'I'm still quite young and expect to be riding until my mid-thirties so I've got enough time to achieve my dream. I know the Olympics are hard and I'll have to produce my best performance yet. But I feel confident.' Liam trains for 30 hours a week - always outside and he reaches speeds of 65 kph. He thinks that cycling professionally is the best job in the world and would recommend it to anyone. His advice to people starting to race is, 'Be prepared for some hard work. If the training was easy, it wouldn't make you faster'.
