Palace gold for Jones
The meeting on July 30, comes just three weeks before the Olympics in Athens, where American Jones and Collins of St Kitts and Nevis will be among the favourites for 100m gold.
Jones, who won at Crystal Palace three times between 2000 and 2002 before taking time off to have a baby, said: “There’s always a world-class field at Crystal Palace and I’ll be looking to gain an advantage by winning so close to Athens. It should be the perfect place in which to fine-tune my form going into the Olympics.”
