A pedal cycle sensor arrangement comprises a sensor mount 34 having a main mounting portion attached to a front fork leg 38 of the pedal cycle. An elongate sensor boom 50 projects forwardly from the main mounting portion and an air sensor member 52 is located at the end of the boom. The air sensor member 52 is held at a position proximal to the upper edge and the front edge of a front wheel of the pedal cycle so as to be in a region of free flowing air in use. A method of deriving actual elevation data for a course (14, figure 1) traversed by a HPV (12, figure 1) is also disclosed. Ambient air pressure is periodically measured at a fixed reference location (28. Figure 1) close to the course 14 and proximal (26, figure 1) to the HPV 12 as it traverses the course 14. The reference and HPV air pressure data for the same point in time during the run is used to determine the elevation of the course at that point in time. Additionally, a low-noise pressure sensor arrangement is also disclosed (60, figure 7) which has a pair of pressure sensors, each having a pressure sensing diaphragm. The sensors are arranged close to one another with their diaphragms in mechanical opposition and the outputs of the two sensors are averaged to produce an overall output.
