"He needs the fitness work to be spot on for the National Trot and he might as well be racing as trialling or doing it at home," says Dickie.
"So that is the way we are going to prepare him this season, less hard work at home but racing him to keep his fitness up."
That is very much the method of many US harness trainers, who because of the searing mile times there keep their horses fresh between races and let the racing do the bulk of the fitness work.
Dickie was thrilled with how the now six-year-old Speeding Spur came through his comeback race, with no signs of the two injuries which have badly affected his career in the last 18 months.
"He gets a lot of vet checks and so far so good and we are optimistic that will remain the case.
"But being an older horse now he is very big and strong and that is another reason he will race there this Sunday, to keep him going forward."
Speeding Spur is the $2 futures favourite for the National Trot, after which Dickie wants to take him back to Victoria to try to win the Great Southern Star for the second time.
Speeding Spur taking on Temporale, Lemond and southerner Bordeaux will be one half of a huge Cambridge highlights package this Sunday as Vincent and Star Galleria are set to clash in the $50,000 Four and Five-Year-Old Futurity.
The race doubles as an automatic qualifier for the A$200,000 Chariots Of Fire in Sydney in February, a race for which fellow Kiwi stars Ultimate Machete and Jack's Legend are also chasing invites via other lead-up races.
