She received multiple calls on her mobile phone, but declined to answer them because the number was unfamiliar.
So imagine Ms Beverly Lim's surprise when she received a text message informing her that she had won a three-night weekend cruise for two from Chan Brothers Travel.
The RCI Voyager Cruise, worth $2,436, was the 23-year-old law undergraduate's prize for winning the early bird draw for The Straits Times Run.
Those who registered for the May 22 run before March 9 were eligible to enter the draw.
"I was totally surprised when I found out I had won the cruise. I will be going with my sister, since I can bring only one person and I cannot choose between my parents!"
Ms Lim is an avid runner who has been taking part in half-marathons since 2014. However, she began running 10km races at the beginning of the year and will be doing that distance at the ST Run.
"Initially, I found 10km races more tiring than half-marathons because you have to maintain a faster pace," she said. "However, the training duration and intensity is less for a 10km race. Since the Sundown Marathon (which she has entered) is the week after the ST Run, I felt that taking on the 18.45km category would be too tiring."
For fellow winner Maureen Lim, 53, it is perhaps a story of beginner's luck as this is the first time that the IT consultant has entered a race.
"I usually exercise in the gym," she said. "However, I was looking to try something new and the ST Run came along at the right time. I saw an advertisement for it a few days before registration opened and decided to sign up."
The cruise is a small consolation for the fact that her children will not be running with her. "I wanted to use this opportunity to have a family activity. But my daughter is overseas for her schooling and my son is not free on that day," she said.
"However, I will still be running with my husband. I hope to be able to have fun and challenge myself."
Registration for the ST Run is still open. Those who sign up before next Wednesday stand a chance to win a Mobot glider worth $1,499. Two Mobot Kenetic eBikes worth $1,499 each are also up for grabs.
