Sebastian Coe has tipped his hat at West Ham's bid to move to the Olympic Stadium after the 2012 Games. West Ham and Tottenham are battling to move to the venue but only the Hammers would retain the running track.
The Olympic Park Legacy Company (OPLC) will make a decision before March and Coe, who has no part in the decision-making process, said: "We made a commitment to track and field to be a part of the legacy of the stadium so, as vice-president of the IAAF, it's not going to come as a huge shock that I am going to defend and help my sport.
"We are told that West Ham are happy to play football within a track and Tottenham have clearly said they are not.
"Conclude from that what you want.''
He added: "It [West Ham's proposal] lives with the commitment we made in Singapore.
"We have had assurances that the tenders will be underpinned by the recognition that commitments were made to the IOC and to the international federations about a track and field legacy, and we have no reason to believe the OPLC will do anything to contradict that.''
