Diane Roy was disappointed after her silver-medal victory in the 5,000-metre wheelchair race on Friday at the Paralympics in Beijing.

The Canadian had won gold in the same event four days earlier, but had to give it up when officials determined the race would be repeated because of a crash that sent several competitors to the hospital.

But Roy didn’t have time to dwell on that disappointment. She had to turn her attention to other events; her schedule at the Beijing Paralympics is gruelling.

Just 11 hours after the demanding 5,000, Roy lined up for the 400-metre (T54) final. She finished third, two spots behind teammate Chantal Petitclerc.

But the Games are far from over for the native of Hatley, Que. Of the six races she has entered in Beijing, four remain.

Next on her list is the 800 metres (T54). She will compete in the heats on Saturday and, if she qualifies, in the final on Sunday.

The 37-year-old athlete will tackle the 1,500 metres (T54) next, competing in the heats on Monday and, if she does well, in the final on Tuesday.

Also that day, she could end up competing in two other races – the 4x100 relay (T53/T54) heats and final.

Roy, who is competing in her fourth Paralympics, will finish with a flourish on Wednesday, squaring off against her rivals in the marathon.

Though it’s gruelling, the event is one of Roy’s strongest. Last November, Athletics Canada awarded her the Fred Begley Memorial Trophy as the country’s top marathon athlete.

She started last season with a victory at the 2007 Canadian Wheelchair Marathon Championships and she later broke the Canadian wheelchair marathon record while competing in the Swiss Racing Series.

Roy was exhausted after the 5,000 Friday morning in Beijing, but a cold bath and a one-hour nap helped her recover in time for the 400. The question remains, however, what will it take for her to recover between each of her remaining races?
