An ice rink is provided having a thermal storage reservoir arranged to regulate the temperature of the ice rink. The ice rink includes a sheet of i ce and a sub-floor for supporting the sheet of ice thereon. The reservoir is mounted adjacent a bottom face of the sub-floor. The reservoir is substantially larger in volum e than the sheet of ice, being filled with particulate material having a high heat capacity. A fluid surrounds the particulate material having a freezing point which is below th at of water. Cooling pipes extending through the reservoir and the sub-floor are arranged to have cooling fluid pumped therethrough for freezing the sheet of ice mounted thereon.
