Methods for providing track condition information include receiving, at a first mobile track control station, a track condition notification. Such methods further include transmitting, from the first mobile track control station to a second mobile track control station in a network of mobile track control stations, the track condition notification. Such methods further include receiving, at the first mobile track control station from a third mobile track control station, affected track sector data regarding an affected track sector. Such methods further include transmitting, from the first mobile track control station to a first mobile track information station within a first vehicle, the affected track sector data, wherein the affected track sector data is configured to be used by the first mobile track information station to determine whether the first vehicle is within the affected track sector.

A system includes a processor configured to receive a track-creation request. The processor is also configured to initiate track recording, responsive to the request and record GPS points corresponding to vehicle movement. Further, the processor is configured to receive a track-completion instruction and store the recorded GPS points, and a line connecting the points, as representing a recorded track.

A hurdle assist includes a flexible tubular lower section comprising a first length and a first slit along the first length, a flexible tubular upper section comprising a second length and a second slit along the second length, and a flexible rod which is slidably removably coupled with the flexible upper section. Attaching the hurdle assist to a hurdle mimics a flexible hurdle for the runner to practice without fear of injury.

Disclosed herein is a portable mountain bike ramp (MTB ramp) assembly comprising a plurality of components including a foldable frame having a plurality of frame sides and a ramp surface on top. The ramp surface is capable of being folded along with the foldable frame to facilitate portability when not in use. A pair of adjustable height legs is provided that is connected to one of the plurality of frame sides using a leg lock. A pair of wheel extensions are adapted in between the pair of adjustable height legs. A rubber foot assembly is provided below each of the pair of adjustable height legs to provide a firm grip on the ground when the MTB ramp assembly is in use.

Provided in this disclosure is a portable night vision tunnel for operating a vehicle in a simulated night environment. The night vision tunnel is formed by assembling a plurality of modules on a driving surface to provide a darkened interior in which the vehicle can be driven. Each of the modules are formed of inflatable arch components each having a light-absorptive interior surface for creating the simulated night environment for operating the vehicle. A fastener arrangement connects each of the arch components to an adjoining one to form a single module. The tunnel includes a portal formed on an able arch component at a respective module proximate to the end of the tunnel. The portal admits the vehicle into the tunnel while maintaining the simulated night environment for operating the vehicle. An air circulation system ventilates and circulates air within an interior space of the tunnel.

A computer-implemented method and system for tracking a user's course using geolocation data is provided. The method comprises obtaining a set of predetermined GPS locations representing a course; tracking movements of a user using a GPS controller; authenticating the movements of the user against the set of predetermined GPS locations while the client terminal is within a predetermined distance of at least one of the set of predetermined GPS locations; and presenting consolidated timing information about the user's movements along the set of predetermined GPS locations. The system comprises a central processing server in communication with a computer network and configured to obtain information from a central database; and one or more client terminals in communication with the central processing server via the computer network, and configured to provide a graphical user interface for user interaction with the central processing server.
