Former Hong Kong Sevens star Warren Warner (pictured) may have retired from rugby, but his participation in this weekend's Oxfam Trailwalker proves he's not yet ready to be put out to pasture. Along with his teammates John O'Hara (team captain), Kris Inglis and Peter Lee, Warner will be taking on the gruelling competition for the first time. Instead of wallowing in his sporting retirement and reaching for his pipe and slippers, he will be reaching for a power bar and his running shoes. 'I had a great rugby career but since I stopped playing I have completed a couple of triathlons and really enjoyed them. It seemed a natural thing to do after all those years of training,' Warner said. 'I'm not one to sit back and do nothing. It keeps you motivated. But I get a different type of enjoyment from doing triathlons. It's more of an individual achievement, while rugby is all about team effort. 'But in a way, that's why the Trailwalker is so good because it's all about being part of a team, too. There are a few former rugby players in our outfit so it will benefit us, as we'll be working as a team, keeping each other going as opposed to just looking after ourselves individually. 'We're pretty excited, but pretty nervous, too. Whatever happens we intend to enjoy every minute of it.' The event is held annually on the MacLehose Trail, a 100km hiking trail across the mountain ranges of the New Territories, starting from Pak Tam Chung, Sai Kung, in the east to Tuen Mun in the west. Teams have to finish within 48 hours. The route was formerly a military drill for Gurkha soldiers before 1986, when it was opened to the public. Warner, 35, may have appeared five times at the Hong Kong Sevens but this chapter of his life he is finding equally as rewarding. Not only has he participated in triathlons, but earlier this year he completed the Comrades Marathon in his native South Africa, an annual 90km trek between Durban and Pietermaritzburg. 'Doing something like an ultra marathon gives you a very different buzz compared to running out at the Hong Kong Sevens in front of a full house, which is absolutely electrifying,' the former Aberdeen and Football Club player said. 'But there's a huge sense of achievement when you compete in something like a triathlon or a marathon, and the Trailwalker will be no different.' Because he and his team members are experienced endurance racers, Warner has only been training specifically for the Trailwalker for the past eight weeks. 'The key thing for us is just to go out there and enjoy it. I think we'd be looking to do it in around 16 to 17 hours but so long as we all finish in one piece that's the main thing,' he said. 'We've also raised quite a bit for charity, which is big plus. Hopefully many people will benefit from our efforts.' This is probably the most salient fact of all as since 1986, more than 42,000 Trailwalker participants have raised over HK$158 million to support Oxfam's various poverty alleviation and emergency relief projects. Happy trails, you could say.
