NICOLE Han, 20, is hoping to win the battle of the sexes and do her bit for charity at the same time.

Together with her sister Merliza Lim, 24, the pair are pounding the roads as part of Nike's Guys vs Girls Challenge.

'It's for a good cause and I get to spend some quality time with my sister. Hopefully more girls will get involved and we can show the boys who's the fitter sex,' said Han.

The girls, led by Hype Records' artiste Rui En, are supporting The Straits Times School Pocket Money Fund while the guys team, led by Media- Corp artiste Tay Ping Hui, will run for the World Wildlife Fund.

The group who clock the longest distance for each week from now until the Nike + Human Race 10km run on Oct 24 will win a portion of the $50,000 total for their chosen charity.

Due to high demand, an additional 500 registration entries for the 10K race will be released on Wednesday at 11am at Nike's flagship store at Wisma Atria. To date, about 9,000 people have signed up for the race.
