O'Sullivan won two silvers in last year's European Championships
Sonia O'Sullivan believes she is on track to be ready for the new athletics season.
The Olympic silver medallist is also confident that she will be at her peak when the World Championships begin at the end of August in Paris.
O'Sullivan was forced to pull out of this month's World cross-country championships in Lausanne because of an Achilles problem.
The 33-year-old mother of two is at present having treatment in Albuquerque from world's leading sports injury therapist, Gerard Hartmann.
O'Sullivan travelled to America from Australia last week when an MRI scan revealed a tear on the troublesome tendon.
''I am receiving twice daily treatments from Gerard Hartmann and spending an hour a day with my foot in an ice bucket,'' O'Sullivan told the Irish Examiner newspaper.
''I am continuing to train in the swimming pool with some aqua jogging and some gym work afterwards.
''Hopefully when I return to Ireland soon, a new scan will be positive and I can get back to some light running.
''Then I will be going full out in the build-up to the summer track season and the world championships in Paris.''
