Horse riding is popular in Epping Forest. Riders need to be registered with the Epping Forest conservators before they are allowed to ride in the forest. Running as a form of recreation in Epping Forest goes back almost to the birth of the sport in the 1870s, including hosting the inaugural English Championships in 1876. Orienteering and rambling are also popular. There are numerous guidebooks offering shorter walks for the casual visitor. The most important event in the ramblers calendar in the area is the traditional Epping Forest Centenary Walk, an all-day event commemorating the saving of Epping Forest as a public space, which takes place annually on the third Sunday in September.
