The Marathon des Sables run for charity (MDS) (Marathon of the Sands) is a six-day, 254 km (156 mile) ultramarathon, which is the equivalent to five and 1/2 regular marathons. The longest single stage (2009) is 91 km (55 miles) long. The event is held every year in the southern Moroccan desert. It is considered the toughest foot race on Earth.
Tom Armstrong, one of our energetic young teachers at St Joseph’s College, set out on this race, to raise funds for his chosen charity. He made it!! and raised nearly $10,000 in the process to help change lives for children in a village in Africa.
