In African wildlife safari lingo, the Big Five animals are the rhinoceros, lion, elephant, leopard and cape buffalo, all of them awe inspiring sights for tourists. In the marathon world, we have the Big Six of world marathons, the New York, Boston, Chicago, London, Berlin and Tokyo Marathons. Some Mumbaikars ran the prestigious Boston Marathon virtually on Saturday.

The virtual marathon could be held any day from September 7 to 14. Virtual running means you run the full marathon course of 42.2km, wearing a satellite watch. The distance and timing is recorded via the satellite watch, connected to the race organising centre. The timing is emailed to organisers. Once satisfied with the fair completion of the race, the runners are mailed their certificates.
