RIO DE JANEIRO (AP) -- The BMX track for next year's Rio Olympics hosted its first test event on Sunday but received a poor grade from riders.
The two-day test event was reduced to one day after some of the world's top riders declined to race on Saturday, citing dangerous jumps and curves.
Rio Organizers tried to modify the track for Sunday, but both men and women wound up using the women's circuit as the men's course was deemed too risky.
Rio Mayor Eduardo Paes and Carlos Nuzman, head of the Rio organizing committee, both said problems should be blamed on the world governing body of cycling, which they said had approved the track.
Officials promised both layouts will be ready in 10 months when the Olympics open.
