Waikato dairy farmer Paul Ryan won't forget this summer in a hurry.

Ryan has seen In Style and Surpass, two horses from a family he's had for 30 years, win a number of black-type races, capped off by In Style's Group One victory in the Railway Stakes (1200m) at Ellerslie.

In Style used her barrier speed to good advantage under jockey Leith Innes, took the lead at the top of the straight and had just enough in the tank to hold off Whosyourmaster and veteran Durham Town.

"You can buy horses at the sales, but to breed them and then win races with them is something else, especially when you have limited numbers," Ryan said.

"We've got four in work now and it's usually only one or two, so this is something to remember. We've only had one Group One runner before."

In Style capped off a rare treble in the Railway after having previously won the two main lead-ups in the north of the North Island, the Listed Counties Bowl and the Group Three Concorde at Ellerslie.

The Railway was also a first Group One win for trainer Danica Guy, who has quietly earned a good reputation from her boutique stable in Matamata.

"I've had horses for 10 years but I've only been training seriously for about three to four years," she said.

Since taking training more seriously she has had good horses like Eclipse Stakes winner Gobi Ranger and honest handicapper Capone, but In Style has been the best to date.

Guy will now set her sights on winning both New Zealand's Group One 1200-metre open sprints, though her main chance for the Telegraph Handicap at Trentham on January 17 is Tomorrowland.

In Style is also entered in the Telegraph but Guy said she wasn't sure the Fast `N' Famous mare would contest it.

Ryan nearly made it a double in the Group Two City of Auckland Cup with Surpass, whose dam is also the granddam of In Style, but the Waikato Cup winner was just beaten by Delago's Secret.
