IntroductionThe equestrian arenas at the 2012 Olympic Games were constructed on a unique raised platform. Arena surfaces can be implicated in risk of injury and affect performance, therefore functional properties were examined to ensure preparation was appropriate for this unusual construction. The objective of this work was to assess surface hardness, load carrying capacity and uniformity during the development of a suitable surface for the 2012 Olympic Games. Data were compared from the Olympic site at a test event in 2011, pre‐London 2012 and from developmental test arenas on and off a raised platform.MethodsIn‐situ systematic sampling was used across arenas. A biomechanical surface tester quantified load carrying capacity (peak load), a Clegg impact hammer was used to assess hardness (peak deceleration) and moisture data were analysed in the laboratory. Contour maps and GLMs (applying the arena's structural features as explanatory variables where appropriate) were used to highlight surface heterogeneity.ResultsSignificant variation in peak deceleration across the surface was detected at the test event in 2011 (P<0.0001). Peak load (P<0.0001) and peak deceleration (P<0.0001) were higher pre‐London 2012, partly due to enhanced stiffness of the base layer. Higher moisture content found pre‐London 2012 (P<0.001) was considered beneficial for surface consolidation. There was no significant difference between data collected on or off a raised platform following the developmental work. Results highlight the importance of effective water management and sub‐surface construction.ConclusionsFindings from this work guided decisions made by the surface providers for the 2012 Olympic Games and advanced understanding of methods most appropriate for assessing arenas in‐situ.Ethical Animal ResearchThis study was approved by the Faculty of Science and Technology ethics committee at Anglia Ruskin University, Cambridge, UK. Sources of funding: The project was conducted as an independent assessment and consultancy for the surface providers Andrews Bowen Ltd, at Greenwich Park for London 2012.
