Described herein is a coaster having a pair of longitudinally-extending and laterally-spaced flexible sled runners which support and define a path for the coaster along a ground surface. The coaster includes forward, intermediate, and rearward lateral struts extending between the flexible runners. The flexible sled runners extend forward from the forward lateral strut to leading rail ends. A longitudinally-extending body support board is mounted above the runners in sucha manner as to allow it to pivot or tilt, relative to the flexible sled runners,about a longitudinal axis. A steering handle is operably connected to the leading rail ends to laterally displace the leading rail ends and to thereby arcthe flexible sled runners. Interlinkage between the steering handle and the bodysupport board pivots the body support board in response to turning the steering handle. Gearing associated with the body support board and the intermediate lateral strut laterally displaces the intermediate lateral strut relative to theforward and rearward lateral struts in response to pivoting the body support board relative to the flexible sled runners. This displacement further arcs the flexible sled runners and thereby curves the path of the coaster.
