With the Welsh Athletics International's athletes ranks swelling up to accommodate a host of international and Olympic stars, world's number 1 in the 800m, Kenya's David Rudisha, might be the latest to join.
Rudisha is a cornerstone of the Kenyan team that will compete in London at the Games, and with Kenya having confirmed the participation of their 4x400m relay in the Welsh Athletics International, it is increasingly likely that the team will feature the superstar.
Rudisha's participation would set up a mouth-watering duel with local hero Gareth Warburton, another 800m runner set to compete in the 4x400m relay.
Furthermore, it would reunite Rudisha with his rival, Botswana' Nijel Amos, meaning the world's number 1 and 2 in the 800m would be both competing at the Cardiff International Sports Stadium.
With other Olympic stars already committed to taking part of the event, such as Kim Collins, Brett Morse, Kerron Clement (USA), Carys Parry, Mervyn Luckwell and Lee Doran, in addition to the relay teams of Australia, Brazil and St Kitts and Nevis, the Welsh Athletics International truly promises to be a festival of athletics on an Olympic scale.
