Challenging playing conditions greeted the golfers on Thursday, as the European Tour returned to Danish soil for the first time in over a decade for the "Made in Denmark" event.
Thomas Bjorn, playing on his home turf, is one of three golfers topping the leaderboard, shooting a 66, good for five under par.
"I drove the ball really really well today and that gives you opportunities on this golf course. So I'm happy with the day, happy with the start. It was pretty solid all the way round and there are just a couple of holes out there that you've got to be careful with and happy to walk off with pars but I put in a nice effort today."
A win would boost Bjorn's chances of making Europe's Ryder Cup team.
He currently shares the lead with Welshman Bradley Dredge and Chilean Felipe Aguilar.
Fellow Dane Thorbjorn Oleson shot 69 and is three back of the leaders
