It brought a screeching halt to a career that should have been about to skyrocket.
Bolt For Brilliance had won a Jewels as a two-year-old and four-year-old, the Jewels not being run during his three-year-old season because of Covid.
In those races he beat arch-rival Muscle Mountain and in May last year he won the Rowe Cup by six lengths over a true champion in Sundees Son.
Now he is back, facing a 50m handicap in a small field.
So can a horse who was that powerful return to such heights after 10 months on the sidelines or has his confidence, so crucial for trotters, been dented?
“I am sure he can get back to that level and he might be even better,” says Herlihy, New Zealand’s most successful harness racing horseman on the track and not one for hype off it.
“A break like that is not disastrous in that once it heals, you shouldn’t have any problems there again, touch wood.
“That is how he feels and looks. He is a happy horse and his work has been good, he seems very sound and his winter coat is coming away.
“So we are training him like the injury isn’t an issue.
“He had been not quite right before he fractured it, so he could even come back better.
“I am really happy to have him back. He is a pretty special horse,” says Herlihy.
Comeback races are often tricky, more so off a 50m handicap.
The sectional times and what sort of drag Bolt For Brilliance can get into the race may determine whether he can win on Friday as much as his undoubted talent.
But a better Bolt For Brilliance is what New Zealand trotting needs as Muscle Mountain was dazzling at Addington last Friday and is will dominate New Zealand’s open class ranks unless his old mate can reignite a rivalry that would make their every clash appointment viewing.
Fans of the trotter, who can be zealots for their beloved gait, may not have to wait long for the next round of Bolt versus Muscle.
“As long as all goes well on Friday night, I have him booked on a flight to Christchurch next week and he could race at Addington next Friday night,” says Herlihy.
“It is not how I would usually start a campaign but two good races will bring him on nicely for Ashburton [October 23] and Cup week and he has had the grounding to handle it.”
With a $650,000 trotting slot race now near certain for Cambridge on The Race night on April 12, a parochial north-south rivalry with a couple of Victorians such as Just Believe and Aldebaran Zeus thrown in could start a new golden era for trotting here.
But before all of that a very good horse will be back doing what he was born to do on his home track on Friday night.
