The surfaces horses train and compete on significantly affect musculoskeletal welfare, with surface characteristics directly influencing injury risk and joint health.
Surface quality is a direct welfare determinant for working horses that is frequently undervalued relative to training load management. A horse trained on consistently good surfaces throughout its career will have significantly lower musculoskeletal injury risk than an equivalent horse trained on poor or inconsistently maintained surfaces, regardless of genetic advantages. Tendon injuries that end careers and cause prolonged pain during healing are substantially influenced by surface-related cumulative microtrauma. Investment in arena maintenance and careful management of work on hard natural ground is a genuine welfare investment.
