This study investigated the effects of timing\u2010based interventions on sleep in 10 national\u2010level Canadian speed skaters prior to a World Cup competition in Beijing (13 time zones crossed). Athletes followed a tailored sleep schedule upon arrival and for the days preceding the competition. Total sleep time in Beijing was not different from Canada (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.254) or pre\u2010season (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.999) and was lower the night before travel (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001) due to the early flight to Beijing. When comparing data with a similar dataset presenting no intervention, bedtime was successfully delayed and resulted in later wake\u2010up time and longer total sleep time. Total sleep time increased by ~10\u2009min\/night, suggesting adjustments in sleep\u2013wake rhythm during the first days upon arrival were still present. Race performance was unaffected by travel, with no time effect on overall rank (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.74). These preliminary findings suggest that individualized timing\u2010based strategies might support sleep regulation and circadian re\u2010synchronization in elite athletes following long\u2010haul travel. Further studies are warranted to confirm these results in larger samples and explore the effectiveness of customized timing\u2010based intervention on different time changes and on performance.\n
