Solo for various reasons. I love the outdoors with the sights, sounds and smells. I also prefer trails over roads but which are mostly not suitable for fast group rides. And I also often stop and take pictures. For me cycling is not so much about the sport but mental recreation. I love to cruise along and discover new trails or routes and the scenery along the way. Sometimes faster, sometimes slower. And on weekends I am often on the bike for a whole day.
