The aim of this study was to assess the reliability of a novel field test of critical running speed (CS). Ten trained

athletics track. Each trial consisted of three distances (1200, 2400 and 3600 metres) that were selected to produce

in the fastest time possible. Participants rested for 30 minutes between efforts. Data were modelled using the linear

(s), and ARC = anaerobic running capacity (m). Results demonstrated a coefficient of variation (CV) of 2.0% (95%

significant difference in CS (m·s-1) across trials (P<0.05). The limits of agreement were ±0.27m·s-1 of the measure

39.9%) for trials 2–1 and 9.8% (95% CL: 7.0–19.6%) for trials 3–2. Although the assessment of ARC is less reliable,

CV data are similar to those reported previously during laboratory-based testing.
