cross course वाक्य

It took two years of coaxing as well as a certificate from a Red Cross course before Marina Varshavsky of Lexington, Mass . finally spoke the words her 13-year-old daughter, Julie Minevich, was dying to hear : " OK, I think you're ready to baby-sit ."
The most plausible, although still speculative reason, was an early resemblance of the racing courses for mountain bikes with the cyclo-cross discipline, with a major difference : the mountain bike racing track was significantly longer ( a cyclo-cross course has 2.5 3.5 km versus 4 + km for a XC track ) and free of artificial obstacles.
