Abstract: 
Background: Test-retest reliability of performing 1-2 bouts of a 30 s Wingate (30WanT) has 5 been shown to improve by averaging 2 bouts. Objective: To investigate whether adding a 3rd 6 bout enhanced or decreased reliability. 7 Methods: On three occasions, 13 triathletes performed three 30WanT’s on a cycle 8 ergometer. Peak power (PP), mean power (MP) and fatigue index (FI) reliability across bouts 9 (Intra-session) and days (Inter-session) were tested. Mean and % change between bouts, 10 typical errors of measurement (TEM) and intra-class correlation co-efficient (ICC) were 11 compared between consecutive pairs of bouts and 3 bouts. Single (1 & 2), averaged 2 (Σ 12 1+2) and 3 bout (Σ 1+2+3) between days using TEMs and ICCs were also compared. 13 Results: Intra-session ICCs for 2 and 3 bouts for PP, MP and FI showed very strong 14 reliability (> 0.7). Three bouts had lower TEM for MP, but 2 bouts had less TEM for PP and 15 FI. Inter-session reliability ICCs were > 0.90 for PP, 0.94 for MP and 0.82 for FI for the 1, 2 16 & 3 bouts with no clear difference between. 17 Conclusions: Performing 1, 2 and 3 bouts showed high to very high reliability, with a 3rd 18 bout not clearly reducing TEM, and in some cases introduces more variability
