Abstract: Indoor riding and training facilities allow for horses to be worked no matter the weather conditions which prevents downtime that could result in lost profits. Research on these facilities has been limited so during the summer of 2018, an anonymous online survey was conducted to begin to characterize indoor arenas. Respondents, grouped by designations of owners, managers, and riders, were asked common questions regarding the region they were from, their main discipline and riding interest, their preference of riding indoors or outdoors, how often they rode, and the average duration of their rides. These questions were analyzed for associations or trends based on whether the respondents were owners, managers, or riders. While many of the respondents were riders at facilities and did not own or manage an indoor arena, trends were visible in the data. All respondents favored riding outdoors rather than in an indoor arena and tended to ride for 30 minutes to one hour on average. In regards to disciplines, most of the managers and owners tended to prefer riding disciplines with a flat emphasis, while riders were evenly split amongst eventing, a flat emphasis, and a flat and over fence emphasis. Examining how often the respondents rode yielded unsurprising results as most respondents who identified as owners and/or managers rode multiple times per day while those who identified as riders typically rode multiple times a week. Understanding how the respondents use and interact with an indoor arena facilitates better opportunities to develop future research as well as allows for programming and publications that can help build and manage facilities that work best for those in the industry using them.
