World 1500 metres silver medallist Hannah England has admitted she is taking a risk with her Olympic hopes after confirming she will miss this weekend's trials in Birmingham.
England suffered a spike to her Achilles in Hengelo three weeks ago and will not race again until the Aviva London Grand Prix at Crystal Palace in mid-July, just three weeks before the athletics programme gets under way in London.
"Of course I'm disappointed to miss the trials, last year I won there and it was the start of an incredible season," said England, who won the surprise silver in Daegu last year.
"But I have to be sensible, if I run too early I could ruin my season. So I have to take a risk that my early-season form and multiple A standards will be enough to gain selection."
The first two athletes in each event at the trials will gain selection for the Olympics, providing they have an 'A' qualifying standard, but a further place is available at the discretion of selectors.
"I'm in a tough event with strong competition, but I know I'm selectable as things stand now and I know I can compete at the highest level if given the chance," England said.
European silver medallist Chris Thompson will join England in sitting out both the trials and European Championships in Helsinki next week as he continues his recovery from a back injury.
He is also considered selectable (for the 10,000m) under the UKA 2012 selection policy.
