You don't have to push it to the limits. You might perhaps just go for a relaxed walk, or do a nice and easy bike ride.
Or do you prefer something more active? Than you simply go for some more intense road cycling or mountain biking. Or perhaps a game of golfing? And of course there is also the possibility to do some water sports. Either on a lake or at the coast.
Maybe you prefer something slightly more extreme? You could go canyoning, rafting and even mountaineering.
