Monday's meeting at Leicester has been abandoned due to a waterlogged track.
Despite passing a Sunday afternoon inspection, the situation became untenable after 20 millimetres of overnight rain.
Clerk of the course Jimmy Stevenson, who called off the meeting after another early-morning check, said: 'We've abandoned because of the relentless rain.
'We'd only had two millimetres (of rain) up to the inspection yesterday and we were raceable.
'But it never stopped from then on and now we are basically underwater.'
