Melbourne Cup winner Vow And Declare and South Australian Derby winner Russian Camelot will add some star power at a winter meeting at Geelong when they head to the course for a gallop between races.

Trainer Danny O'Brien said the pair would work between races on Friday as part of their build-up towards the spring.

"We're taking Russian Camelot and Vow And Declare into Geelong races tomorrow and they'll have a gallop between races there," O'Brien told RSN927.

"And then we've got a set of trials at Flemington on the 10th of August where a lot of our spring horses will have their first little stretch of their legs then."

Both Russian Camelot and Vow And Declare are pencilled in to begin their spring preparations in the Group One Makybe Diva Stakes (1600m) at Flemington in September.
