As if wandering around the Angkor temple complex wasn't exhausting enough for most people, those with more energy than sense can help to raise funds for Cambodian children by taking part in the annual Angkor Wat International Half-Marathon and Bike Race in partnership with Hearts of Gold, a Japanese organization working to assist land mine survivors, and Village Focus International. The races will take place this December 16 (Bike Race) and 17 (Half-Marathon) on a course that will wind through the temple complex. All proceeds will benefit land mine survivors and VFI child protection projects in the country. Just in case you are keen to put yourself through this extreme fitness program for a good cause - its 21 kilometres for the half-marathon and 85 kms for the bike race - go to the VFI website here. And good luck.
