The 29-year-old struggled at the physically demanding Cadwell Park circuit, only taking two points as his fitness problems continued, and he hopes to use the Leicestershire outing to show boss Paul Bird he is worthy of a ride next year.
The three-time BSB race winner’s season has been hampered by a series of injuries and operations, and so far a solitary podium at Oulton Park is all he has to show for his efforts.
Though it is still mathematically possible, it would require remarkable circumstances and at least one trip to the podium for Easton to steal a Showdown place this weekend – which Easton is happy to admit is not a realistic aim given everything he has been through this season.
“I’m still struggling physically and Donington is as challenging as Cadwell in some areas, it’s tough on braking in a lot of areas,” he said.
“It’s tough for me at the moment because I’m not where I want to be in terms of fitness.
“Cadwell was poor, there’s no denying that. I need to be better Donington and a finish in the top eight would be fantastic – nothing is confirmed for me next season so I guess I need to prove to the team I’m worthy of a ride next year.
“I raced there in 2009 but missed out in 2010 and 2011, but I’ve won there before in my career and I know what to expect.
“The pace of the bike is really good so it’s just down to how quickly I can get back to my best.”
While much of the focus will be on the remaining Showdown places and the season finale, Easton is raring to go for a triple-header of his favourite circuits – and believes a strong result at Donington will set him in good stead for his favourite part of the calendar.
“We’ve got Assen and Silverstone back to back and they are great circuits, and then the season-finale at Brands Hatch so it’s a really exciting part of the season,” he said.
“The level of competition is going to be higher than ever starting this weekend and I really enjoy that environment so I can’t wait to get racing again.”
