Wiggins has changed his goals after starting with hopes of overall victory
Team Sky's Bradley Wiggins still has his sights set on securing a top-10 finish in this year's Tour de France despite a difficult start to the event.
The British rider was fourth last year and came into this year's Tour with serious hopes of overall victory, but lies 16th after nine stages so far.
"I'll just do my best every day," the 30-year-old said.
"I don't think general classification's over in terms of getting a respectable position. That may be top 10 for me."
Wiggins, who rode for the Garmin team in the 2009 Tour, is one of eight British riders in the Tour, only two of which are in the top 100.
He came into the event full of optimism, describing his preparation as "near-perfect".
"Without bad luck and everything I think I'll get the result I want," he said in the build-up to the Tour.
"It is a hard race but if it's going to be hard for me, you can guarantee it's going to be hard for everyone else."
But he has found the going tough and his hopes suffered a further setback when team-mate Simon Gerrans, who had been picked specifically to help Wiggins in the mountain stages, was ruled out after breaking his arm on Sunday.
"We'll just keep pushing on, see what happens, do our best and that's all we can do now," said Wiggins
"I don't want to give up, there's been so much support out there on the road, it's been fantastic.
"We put everything into it, it hasn't worked - it's not because we haven't tried. That's just the way it goes. That's life, unfortunately."
Team Sky sports director Sean Yates said it was now up to their other riders to take some of the pressure off the triple-Olympic gold medallist.

"It's obvious now where we are, we're top 15 on GC," said Yates. "It's already been a fairly successful Tour but I think we should put more emphasis on trying to pick off a stage win.
"Bradley can still move up and gain top 10, top five, you never know. But I don't think at this point we're in a position where we should put all our eggs in one basket."
One rider having an even worse time than Wiggins is David Millar, who was the last Briton to wear the leader's yellow jersey in 2000.
He finished Monday's ninth stage in 181st place, 42 minutes 45 seconds behind winner Sandy Casar, after a day plagued by a stomach problem and back spasms.
"Today represents a brand new entry into my top five worst-ever days on a bike," the Team Garmin-Transitions rider said.
"I spent 180 km by myself convinced I was going to abandon or be eliminated. At 100 km to go I was 30 minutes down on the leaders.
"All I could see in my head were the contours of the stage from the maps. I broke it up into five km climbs and kept thinking 'I have to get through this'."
