Alana Barber has no qualms with the tough road laid out for her to qualify for Rio.
The race walker has reached the Athletics New Zealand B standard for the Olympics once in the 20km event and will aim to do it again at a World Cup race in Rome next weekend.
Barber says she's throwing all her eggs in one basket but knows once she qualifies she will be on track for a good showing.
She says once she gets the qualification standard she can concentrate on a top-12 finish at Rio.
Barber hopes competing alongside elite race walkers next week will lift her to a second B standard.
She has had physiology tests to determine how far she can go and says the tests showed she's capable of doing the A standard if conditions go her way.
Barber says it'll be a very strong field and she's doing that event to help push her to a good time.
