The researchers referred to the service quality scales proposed by Brady and Chang (2002), Cronin (2001), and Ko (2000) for developing the Service Quality Scale of Racing. 454 adult runners in the Terry Fox Run participated in this research as the surveyed subjects for verifying the validity and reliability of the scale. The data analysis was conducted by the statistic software of LISREL8.54. The findings showed that the service quality scale of races has passed the extrinsic quality test with the overall fit measures of the measurement model as the following: X2=273.93, GFI=0.93, RMSEA=0.05, SRMR=0.07, CFI=0.92, NNFI=0.91, PNFI=0.73, CN=203.51, X2/df=3.19. The test result of the intrinsic fit measures of the model, from the construct reliability of the overall race service quality, 0.80, revealed high reliability. In terms of the convergent validity, all the observed variables and latent factors have been significant. This indicated that the model has convergent validity. As for the discriminant validity, it showed that the correlation of the latent variables could be discriminated, and the discriminant validity of this scale was supported. Therefore, the foregoing findings identified good validity and reliability of the service quality scale of racing.
