The "Momentum Big Heart 750: run for a purpose" is an epic charity event which is currently taking place, and all money raised will go to the Heart and Stroke Foundation of South Africa.

The “750” in its title is derived from the route length: a muscle-crunching 750km from Centurion to Durban. Needless to say, this is a mammoth event, but what makes it even more challenging is the fact that eight average men will complete the relay run.
The participants, who are all Momentum employees, started this gruelling challenge on Monday 19 June and will finish in Durban on Friday 24 June. These brave men wanted to rise to this challenge not only to make a difference to their own lifestyles, but also to those of all South Africans.
MapIT, the leader in digital mapping, which has also provided support for the runners and the spectators of other major athletic events, has proudly made its online mapping service available to The Momentum Big Heart 750 Challenge.
“MapIT is very proud to supply this vital logistical support. Its benefits will be felt by the runners, organisers, and even the fans,” says the company’s MD, Etienne Louw.  
The interactive online map will not only allow runners to familiarise themselves with the route, kilometre markers and daily stops, but will identify refreshment stations and parking zones, in addition to co-ordinating the routes of the support teams, keeping them up-to-date on meeting spots or service "hot-spots".
The map also allows "zoom in" functionality, so that all details are laid bare, and nothing is left to guess-work. The map is already available on the Internet.
The zoom in-or-out tool can be found in the top left-hand corner of the map, and by keeping the mouse left-clicked over the map, users can shift it around within the window. To the left of the map, users will see the colour-coding for each day’s route.

The “750” promises to be a gruelling route for the runners; there’s little doubt about that. They should take comfort, however, in the knowledge that technology is on their side.
