Two-time Olympic gold medallist Mo Farah will not be given any financial incentives to take part at next year's IAAF World Half Marathon Championships.
The event is due to take place in Cardiff and a number of elite athletes are expected to compete as part of their preparations for the Olympic Games in Rio.
"At the moment we're definitely not talking about financial inducements," organising committee member Matt Newman is quoted as saying by BBC Sport.
"What we're talking about I guess are emotional and practical inducements to make sure the event does fit into his agenda in an Olympic year.
"It's for him really to an extent to give something back to the public of the UK as well."
Last weekend Farah broke the two-mile indoor world record in Birmingham.
