I had the pleasure of sharing the same office with Anis not too long ago for a few years. She exercised once a while, maybe go treking thats all. Mother of a few kids etc. She said she used to cycle a bit before joining the working force.
I got a shock on KL Marathon day when Anis gave her greetings and said she completed the Marathon in 5 hrs 18 mins. That is really something. Even I can't do it. Definitely one of the greatest success stories I have come across.
