 The brook on the landing side of Becher's was filled in and, after the 2011 race which also saw an equine fatality at the obstacle, the incline on the landing side was levelled out and the drop on was reduced by between 4 and 5 inches (10–13 cm) to slow the runners.Other fences have also been reduced in height over the years, and the entry requirements for the race have been made stricter.Screening at the Canal Turn now prevents horses being able to see the sharp left turn and encourages jockeys to spread out along the fence, rather than take the tight left-side route.
