What I'm looking out for in Doha
This weekend's indoor event in Doha is first time that an athletics World Championships of any sort has been held in the Middle East and with the inaugural 2010 IAAF Diamond League meeting here in May, all concerned are looking for a good show.
This is not just a big weekend for the host nation, who have been on a huge promotion drive drumming up excitement in the local neighbourhoods and have spent a lot of money on marketing.
It is also a big weekend for some of the world's best athletes and biggest world indoors, in terms of participation, since the first, in .
So which athletes are likely to please the fans - and the organising committee - in the Aspire Dome in Qatar's capital?

I'm Katharine Merry, former world 400m number one and an Olympic bronze medallist at Sydney 2000. I'm now a mentor to junior athletes as well as working in radio and TV, and as a trackside presenter at major events. I'll be aiming to give you a behind-the-scenes insight to the world of athletics.
