Llangollen on the River Dee hosts white water Slalom canoeing and kayaking, being host to International and UK events. The International Canoe Federation (ICF), the European Canoe Union (ECU) and the British Canoe Union (BCU) all hold events in Llangollen. Cricket, football and rugby union teams play at Tower Fields, which overlooks the town and the International Eisteddfod field and pavilion. Thermals rising up the valley sides to the south of the town are used for paragliding. Mountain bikers enjoy the hills. Llangollen was the starting point of the first massed-start cycle race held on British roads, on 7 June 1942. The 59-mile Llangollen Wolverhampton race was organised by Percy Stallard in defiance of the sport's governing body, the National Cyclists' Union, but with approval from all police chief constables through whose districts the event ran.
