While Life Time is committed to planning our scheduled events in 2021, we don’t know the extent to which our lineup will continue to be impacted by COVID-19. As such we have revisited and revised our policy on entry refunds and deferrals to provide more athlete flexibility for event participation. A link to this policy will be included in the registration process, whereby participants must indicate that they understand and accept the terms.
