The first Old Mutual Om Die Dam was run in 1991 and has grown into one of the finest ultra-marathons in South Africa, offering a great family day out with it’s diversity of four different race distances, it is a race for everyone. Only an hour’s drive from Johannesburg, or around 40 mins from Pretoria, a trip to the Hartebeespoort Dam is always a pleasure, and if that wasn’t enough the magnificently scenic routes will have you wanting to do a second lap when you reach the finish.

The start is in the road at the entrance to Hartbeespoort Holiday resort in a south-easterly direction on the R513. After approximately 3,5km runners will turn left onto the R104 main road towards Scott street, passing under the Arch de Triumph and crossing the Dam wall. Then you will be taken on a scenic loop through the suburbs of Schoemansville and Ifafi and alongside the water front to Meerhof and towards the R511 main road. After this the route heads on past Jasmyn Farm Stall towards Saartjies Neck which is the first of the significant hills and encountered at approximately 16 kilometers.

 

But Beware Saartjies!

On the other side of Saartjies Neck the route turns right crossing the N4 toll road and right again before continuing straight onto the R104 past Pelindaba towards Broederstroom where the R104 joins the R512. The route continues on the R512 towards Pecanwood Golf and Country estate. After a while, still on the R512, the route will go right across the westerly point of the dam and right again towards Commando neck, the second of the significant hills at around 42,5 kilometers.

Once over the hill the route goes onto the R513 at Damdoryn and back to the finish at Hartbeespoort Holiday resort.

At Meerhof  be sure to look out for the children at Meerhof School, one of our official charities, who will be handing out traditional ‘melktert’ to the exhausted runners. The half marathon and shorter races run mainly around the suburbs of Hartbeespoort and are generally flat, easy and fast.

It can be hot in Harties at this time of the year, but the event is renowned for its superb refreshment stations, with 19 in total on the ultra route, spaced every 3km for the first half, and then every 2km from halfway. Besides water and Coke at all stations, some also offer potatoes, bananas, chocolates, jelly sweets and other ‘morale lifters’. The organisers know how to look after tired runners! That attention to detail is just part of what makes this race one of the benchmark races on the South African race calendar. See you there!
