Mansfield which competes as Nova Centurion. The Sherwood Swimming Baths adjacent to the former Sherwood Colliery was refurbished and opened in January 2010 as the "Rebecca Adlington Swimming Centre". The 25-metre pool was widened at the expense of losing the tiered public seating and has a new, small, endless stroke-improvement training pool with variable-resistance water flow. The complex uses a ground-source heat pump backed by a biomass boiler burning wood pellets prepared from waste by a local wood yard, to reduce its carbon footprint. At the Beijing 2008 Olympic Games, a Mansfield contestant, Rebecca Adlington, won two gold medals, for 400
Sport in the United Kingdom World Championships, seven of them gold, and nine gold medals at the 2008 UCI Track Cycling World Championships in Manchester. The investment paid off in the 2008 Olympics; British cyclists brought home gold medals in seven events, most notably Chris Hoy who became the first British Olympian to win three golds at one Olympiad, earning him a knighthood. Other successes include Rebecca Romero and Victoria Pendleton. Success at road racing was also limited, with the United Kingdom being the only major nation not to have a Tour de France champion, until Bradley Wiggins' victory in the 2012 Tour de France.
