The International Olympic Committee wants all sports venue locations for the 2012 London Games to be finalized by March. Gilbert Felli, the IOC's executive director of the Olympic Games, said Wednesday that London organizers are still deciding on two venues -- a joint facility for badminton and rhythmic gymnastics and a location for shooting.

Mixed gender events and teams made up of athletes from several countries are some innovations the International Olympic Committee has included in the 2010 Youth Olympics sports programme, it said on Wednesday.

London 2012 Olympic Games organisers will finalise the venues for all sports by March next year, the International Olympic Committee said on Wednesday.

Dutch world half-marathon champion Lornah Kiplagat said on Wednesday she will quit track and cross country running and run on the road only.
