Grand National to knock off. Some of the jumps carry names from the history of the race. All 16 are jumped on the first lap, but on the final lap the runners bear to the right onto the run-in for home, avoiding The Chair and the Water Jump. The following is a summary of all 16 fences on the course: Height: Often met at great speed, which can lead to several falls, the highest being 12 runners in 1951. The drop on the landing side was reduced after the 2011 Grand National. Height: Prior to 1888 the first two fences were located
1849 Grand National the third fence on the second circuit, which resulted in several competitors being knocked out of the race. The custom among riders at the time would have been to continue in the race unless impossible to do so, regardless of how many times they had met with mishap. Therefore, many of the competitors would have been remounted once or more during the race, or put to fences again after refusing. Only those horses that had been injured, run loose after falling, persistently refused an obstacle or had riders too injured or fatigued to continue would not have completed the course.
