Brian Cookson, president of the UCI, cycling's governing body, has expressed frustration at the lack of bidders for the 2015 Track Cycling World Championships and preceding Track World Cup series, but claimed that hosts will be announced shortly.
With the 2013 Track Cycling World Championships in Cali, Colombia having ended yesterday, attention has now turned to the 2014-15 calendar, which looks ominously blank.
The first of three World Cup series events is scheduled for November 7 to 9, with subsequent stages in December and January 2015, ahead of the world championships from February 18 to 22. But none of these events have host cities yet.
It is understood that Melbourne, which staged the 2012 world championships, and Aguascalientes in Mexico, host of leg two of the 2013-14 World Cup series, are potential hosts for the showpiece event in 2015.
There is greater concern surrounding hosts of the World Cup series, which offer qualification points for the world championships and the Rio 2016 Olympic Games.
Speaking on the sidelines in Cali, Cookson said: "We have a number of proposals now on the table and we'll be making a decision very shortly. It's not ideal, but it's a real-world problem. The real-world problem was that there weren't any bidders coming forward.
"The ones that were interested originally had withdrawn, so we are now proactively looking and talking to people and I'm optimistic that we'll get a solution in time so everyone will be able to book their flights."
Cookson, who was elected as UCI president last September, said he will meet with the track commission to potentially review the bid process for the World Cups and world championships, "where we seem to have had a problem of getting sufficient people interested."
London has already been awarded the 2016 Track Cycling World Championships, which will be staged at the city's Olympic Velodrome.
The UK last hosted the UCI Track Cycling World Championships in 2008, in Manchester.
Minsk in Belarus staged the 2013 event.
