Tour de France 2015: Rohan Dennis dons yellow in Utrecht heatwave

    Australia's Rohan Dennis is the first man to don the yellow jersey in the 2015 Tour de France.

    (CNN)Australia's Rohan Dennis set a pace as blisteringly hot as the sweltering heatwave in the Dutch city of Utrecht to don the first yellow jersey of the 2015 Tour de France with a record-breaking ride.

    The BMC rider upset more fancied contenders to clock 14 minutes 56 seconds for the 13.8km individual time trial, his average speed of 55.45kph, the fastest in Tour history for a stage of this type.
    He finished five seconds clear of former world time trial champion Tony Martin (Etixx-Quick-Step), with another famed performer against the clock, Fabian Cancellara (Trek Factory Racing) in third, a further second adrift.

      Heat factor

      A bitterly disappointed Martin complained that the heat, topping 30 degrees Centigrade, (86 degrees Fahrenheit) and a lack of breeze with so many spectators lining the streets of the built up city, had compromised his effort.
      Dennis, an earlier starter, had set a time which proved unbeatable as the temperatures soared.
