Equestrian sport is well known worldwide. It is Sweden’s second largest sport and the only Olympic sport where all competitors compete at the same terms regardless gender and age. Equestrian surfaces are a debated topic, vital for the safety of both horse and rider, and there are several different ways of how to construct an arena. Actually, two courses with the same construction can act differently depending on the used material and its properties. A problem regarding footing is people´s lack of knowledge about the ingoing parameters. Choice of material, conditions in the ground at construction site, choice of foundation, choice of top layer, maintenance and discipline will all affect the outcome. Another problem is that the assessments almost always are subjective, which does not give a proper idea about the footing. The purpose of performing this study was to investigate different materials and evaluate if there are any similarities between different foundations with the same top layer and vice versa. This was done in two steps, a laboratory test and a practical test. The laboratory test was done in order to look closer at the materials and find possible deviations from the specification, this by doing a sieving and a Camsizer test. The practical tests where done by constructing test areas, at a field on a farm close to Gothenburg, with different foundations and varying top layers in the measurements. By using measurement equipment, called OBST, developed to measure equestrian surfaces the characteristics of each test area could be collected as data from which any similarities and differences could be evaluated. In the outcome from the laboratory test a big deviation were seen, some of the materials that were ordered as the same fraction differed a lot from each other. The data from the practical test with the test areas showed that the foundation has a role in the footings properties since the areas with the same material were shown to have very varying characteristics. Moreover, the top layer does influence as well, which were seen by different values on the functional properties were the top layer of sand mixed with fibre got the highest grip meanwhile the top layer with a fraction of 0- 8mm got less cushioning.
