Things are more stately in the dressage, with riders trotting their stick horses with intricately decorated stuffed heads before the discerning eyes of the judges.
Some 260 riders from 22 countries – mostly women and girls aged between 10 and 20 – turned up to compete at the 11th annual Finnish championship held in the town of Seinajoki.
But despite its vast international reach, from the Arctic to Argentina, hobby horsing is a sport that dares not speak its name.
Despite its soaring popularity, it is not officially recognised as a proper sport in its birthplace.
“We have faced so much bullying and judgment,” rider Nara Arlin, 24, says.
“We know what everyone in the hobby horsing [world] has been through … I think that is the main thing that pulls us together.”
Invented in Finland more than a decade ago, hobby horsing has taken off at a gallop across the globe.
“It is growing every year,” says Julia Mikkonen, the chair of The Finnish Hobbyhorse Association.
This year’s championship was “the biggest we have had so far”, she adds.
Beyond the whimsy, great strength and skill is required to jump the obstacles while holding the hobby horse. Some top competitors could give elite hurdlers or gymnasts a run for their money.
“If you jump over obstacles, your hip mobility has to be absolutely insane,” says Mikkonen, 20, with some fences up to 110cm (3.6 feet) tall.
She estimates there are around 10,000 hobby horsers globally. “Of course we are all dreaming of having a world championship one day.”
Jojo Hanninen, 19, sits down after her dressage event. “I am still a bit breathless but I am happy with my performance,” she says.
To succeed in the sport you have to channel your inner centaur, she says.
“In hobby horsing, my legs are the horse … I am both horse and human,” she says.
Hanninen’s hobby horse is a grey called Toope, with glittery reins and pink ribbons adorning its white mane.
Competitors go to great lengths with their horses – which are also exhibited and judged – modelling and sewing the heads and adorning them with decorations.
“Hobby horses are art,” says Arlin, who makes her own.
With the cheers of the crowd still ringing in her ears after an impressive show-jumping round, she hailed the sport as “the best hobby ever”.
“You are doing so many things with your hands, brain and the whole body.”
Like many of her peers, Arlin found hobby horsing through play as a child.
“But the older I became, it became more serious,” says the rider, who trains by riding real horses, working out in the gym and doing pole dancing.
Rainbow flags in the arena reflected the tolerant values underpinning the community.
“Horses are mostly seen as a girls’ sport, but that is not correct. Anyone can come no matter what gender,” Mikkonen says.
Every enthusiast spoken to praised the welcoming community that kept them devoted to hobby horsing despite the scornful attitudes all encountered at some point.
“We have each other’s backs,” Arlin says.
