and the runners had to jump into the road and then back out of it. Fence 13 & 29 Height: A plain obstacle that comes at a point when the runners are usually in a good rhythm and thus rarely causes problems. Fence 14 & 30 Height: The last fence on the final lap and which has often seen very tired horses fall. Despite some tired runners falling on the 30th and appearing injured, no horse deaths have occurred at the 30th fence to date. On the first lap of the race, runners continue around the course to negotiate two fences which are only jumped once: Fence 15 – The Chair Height: , preceded by a 6 ft (1.83 m) wide ditch This fence is the site of the accident that claimed the only human life in the National's history: in 1862, Joe Wynne fell here and died from his injuries, although a coroner's inquest revealed that the rider was in a gravely weakened condition through consumption. This brought about the ditch on the take-off side of the fence in an effort to slow the horses on approach. The fence was the location where a distance judge sat in the earliest days of the race. On the second circuit, he would record the finishing order from his position and declare any horse that had not passed him before the previous runner passed the finishing post as "distanced", meaning a non-finisher. The practice was done away with in the 1850s, but the monument where the chair stood is still there. The ground on the landing side is six inches higher than on the takeoff side, creating the opposite effect to the drop at Becher's. The fence was originally known as the Monument Jump, but "The Chair" came into more frequent use in the 1930s. Today it is one of the most popular jumps on the course for spectators. Fence 16 – Water Jump Height: Originally a stone wall in the very early Nationals. The Water Jump was one of the most popular jumps on the course, presenting a great jumping spectacle for those in the stands and was always a major feature in the newsreels' coverage of the race. As the newsreels made way for television in the 1960s, so, in turn, did the Water Jump fall under the shadow of its neighbour, The Chair, in popularity as an obstacle. On
