Dominique Mayho endured a torrid time-trial at the Pan American Continental Championships in Mexico yesterday, failing to finish the course because of mechanical problems.

Mayho, whose own time-trial bike was damaged in transit to Mexico, was forced to use his team-mate Mitchell’s bike, but withdrew from the under-23 race after the first lap, uncomfortable with the change in equipment.

Mitchell enjoyed better fortunes in her women’s time-trial, finishing 13th out of 18 starters in a time of 29min 07sec, 2:40 behind race winner Evelyn Stevens, of the United States.

“I am very happy with my performance today and I think that it is largely due to my overseas training the last few months,” Mitchell said.Peter Dunne, the president of the Bermuda Bicycle Association, added: “Mitchell’s average speed of 40.7kph was amongst the best she has ever turn in and, considering the challenges which the altitude present for those who live at sea level, this should be taken as a positive sign.”

Mayho and Mitchell will compete in the road race in the Puebla tomorrow.
