Nothing gets in between Christina Kui and her running. Not even breast cancer. A month after undergoing surgery in 2011, the energetic Kui ran the Tokyo Marathon. If she'd run just 14 seconds faster than her four hour, 13 second finishing time, she would have qualified for the Boston Marathon.
It is not, however, results that motivate Kui, but the desire to keep moving. The executive assistant is taking part in the Hong Kong Marathon next month for the fifth time, when she'll run the half marathon. It may not be her best performance - she's been experiencing joint pain from a change in medication - but it certainly won't be her last.
Exercise, she claims, helps to speed up her recovery. She runs up to four times a week and swims every other day. Besides, she says, her running training is practical too. If she's late, she can run for the bus or ferry without breaking a sweat.
I have been swimming for some 20 years now, but I find distance running is an amazing skill to have. Plus, it keeps me very fit.
about 10 years ago when I signed up for the 2004 Ironman New Zealand in Taupo. I didn't even know what an Ironman was before I said "yes" to taking part. (It was a 3.8 kilometre swim, 180.2 kilometre cycle and a 42.2 kilometre run.)
