Money stuck in escrow account after bankruptcy filing

Grand Slam Track athletes have still only received 50% of their earnings nearly 15 months on from the collapse of Michael Johnson’s ill-fated venture.

Many of the Grand Slam stars are at the Ultimate Championships in ­Budapest, where they are competing for a $10m (£7.4m) prize fund, the richest in the sport’s history, with first prizes of $150,000 (£111,000) for individual events.
